The Rock Cycle
by _________________
The rock cycle is a process in which rocks are continuously transformed between the three rock types igneous, sedimentary and metamorphic .Conversion to metamorphic rocks requires conditions of increased temperature and/or increased pressure, conversion to sedimentary rocks occurs via the intermediate stage of sediments, and conversion to igneous rocks occurs via the intermediate stage of magma. Increased temperature and pressure occurs in subduction zones and in areas where two plates of continental lithosphere collide to produce a mountain range, while increased pressure without increased temperature is produced when sedimentary rocks are deeply buried under more sediments. Sediments are produced when rocks are uplifted, weathered and eroded, and the resulting detrital material deposited in marine or terrestrial basins. If the sediments are buried under further layers of sediment, they can become lithified to produce a sedimentary rock. Magma is produced when rocks are melted. This melting can occur when a lithospheric plate descends into the Earth’s crust at a subduction zone, or when a mid-ocean ridge opens up and produces decompression melting in the athenosphere under the ridge. When the magma solidifies, it becomes an igneous rock.
The rock cycle has many alternative pathways. The following diagram illustrates one of these and gives an indication of the plate tectonic setting where it occurs:
Which of the following undercut farmers in developing countries?
A)
competition among local food growers
B)
donations from other countries
C)
disruptions in distributions
D)
transportation of food over long distances
NOT A
Answer: Might it be B? Either B or C.
Explanation: I would suggest B since developing country farmers suffer when other countries export cheap foods to them. This creates competition and can hurt the farmers’ source of income, essentially undercutting them. If it isn’t B, it has to be C since I got D wrong :)
Answer:
B) donations from other countries
Explanation:
I got it right on Edge :)
Biomes are classified based on the type of vegetation, which is dependent on
Explanation:
Terrestrial biomes are distinguished primarily by their predominant vegetation, and are mainly determined by temperature and rainfall. Differences in temperature or precipitation determine the types of plants that grow in a given area . Regions of similar climate and dominant plant types are called biomes.
Climate is the major factor affecting the number and diversity of plants that can grow in a terrestrial biome. Climate determines the average temperature and precipitation, the length of the growing season, and the quality of the soil, including levels of soil nutrients.
The primary factor which determines a biome is the climate. Temperature and precipitation essentially determines what kind of growing season or soil quality the terrain may have,which therefore affects the growth of plants living there.
Why do different types of cells have different structures/ shapes
Answer:
Cells have different shapes because they do different things. The shapes of cells have evolved to help them carry out their specific function in the body, so looking at a cell's shape can give clues about what it does. Neurons are cells in the brain and nervous system.

Do humans have the right to colonize other planets, such as Mars? What challenges will humans have colonizing Mars?
If you take a look at evolution on Earth, 99.9 percent of all life forms have gone extinct. When things change, either you adapt or die. That’s the law of Mother Nature. We face various hazards. First of all, we have self-inflicted problems like global warming, nuclear proliferation and bio-engineered germ warfare. Plus, Mother Nature has hurled at the Earth a number of extinction cycles. The dinosaurs, for example, didn’t have a space program. And that’s why the dinosaurs are not here today.

If my starting energy at the producers is 1500 kcal, using the 10% rule, how much energy is available to the tertiary consumers?
Answer:
1.5 kcal
Explanation:
The ten (10) percent rule involves how only as low as 10% of the available energy is transferred to each organism in trophic levels. In an ecosystem, the order of trophic levels are: producer ➡ primary consumer ➡ secondary consumer ➡ tertiary consumer.
According to this question, 1500 kcal of energy is starting at the producer level. Hence;
- 10% of 1500 kcal = 10/100 × 1500 = 150 kcal will be available to the primary consumer
- 10% of 150 kcal = 10/100 × 150 = 15 kcal will be available to the secondary consumer.
- 10% of 15 kcal = 10/100 × 15 = 1.5kcal will be available to the tertiary consumer.

6 A person becomes infected with a pathogen, such as a virus. What internal stimulus most
likely takes place in order for their body to maintain homeostasis?
А
Dehydration due to lack of water
B
Their core temperature increases
с
The production of hormones is activated
D
Sweating occurs to help cool the body down
Answer:
B. Their core temperature increases.
Explanation:
Pathogens are organisms such as virus, fungi, bacteria, protozoa, worms that causes diseases to its host.
Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment ideal to enhance life and proper functionality.
If a person becomes infected with a pathogen, such as a virus. The internal stimulus that most likely takes place in order for their body to maintain homeostasis is that their core temperature increases. This is because pathogens such as a virus do not thrive or survive in a hot environment; they're naturally allergic to high temperature (heat).
Additionally, in order to reduce pathogens and prevent illness, it is very important to cook our food to high degrees of temperatures. These pathogens are usually destroyed by heat, so it's necessary and important to properly cook food to a high temperature by grilling, boiling, frying, roasting and baking. Also, a hot-holding unit can be used to store food in order to reduce pathogens.
It is an
advantage for two species to share the same niche.
Answer:
False.
Explanation:
The competitive exclusion principle states that when two species compete for exactly the same resources (thus, they occupy the same niche), one is likely to be more successful. As a result, one species "outcompetes" the other species, and eventually the second species is eliminated.

Explanation:
Explain how a carbon atoms moves From primary consumers to secondary consumers
Explain how a carbon atoms moves From consumers back to the atmosphere (2 different methods)
Explain how a carbon atoms moves From consumers to fossil fuels
Answer:
There are a few types of atoms that can be a part of a plant one day, an animal the next day, and then travel downstream as a part of a river’s water the following day. These atoms can be a part of both living things like plants and animals, as well as non-living things like water, air, and even rocks. The same atoms are recycled over and over in different parts of the Earth. This type of cycle of atoms between living and non-living things is known as a biogeochemical cycle.
All of the atoms that are building blocks of living things are a part of biogeochemical cycles. The most common of these are the carbon and nitrogen cycles.
Tiny atoms of carbon and nitrogen are able to move around the planet through these cycles. For example, an atom of carbon is absorbed from the air into the ocean water where it is used by little floating plankton doing photosynthesis to get the nutrition they need. There is the possibility that this little carbon atom becomes part of the plankton’s skeleton, or a part of the skeleton of the larger animal that eats it, and then part of a sedimentary rock when the living things die and only bones are left behind. Carbon that is a part of rocks and fossil fuels like oil, coal, and natural gas may be held away from the rest of the carbon cycle for a long time. These long-term storage places are called “sinks”. When fossil fuels are burned, carbon that had been underground is sent into the air as carbon dioxide, a greenhouse gas.
Recently, people have been causing these biogeochemical cycles to change. When we cut down forests, make more factories, and drive more cars that burn fossil fuels, the way that carbon and nitrogen move around the Earth changes. These changes add more greenhouse gases in our atmosphere and this causes climate change.
The element carbon is a part of seawater, the atmosphere, rocks such as limestone and coal, soils, as well as all living things. On our dynamic planet, carbon is able to move from one of these realms to another as a part of the carbon cycle.
Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.
Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.
Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.
Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.
Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere. Most of the remainder becomes dissolved in seawater.
Carbon moves from the atmosphere to the oceans. The oceans, and other bodies of water, absorb some carbon from the atmosphere. The carbon is dissolved into the water.
Carbon dioxide is a greenhouse gas and traps heat in the atmosphere. Without it and other greenhouse gases, Earth would be a frozen world. But since the start of the Industrial Revolution about 150 years ago humans have burned so much fuel and released so much carbon dioxide into the air that global climate has risen over one degree Fahrenheit. The atmosphere has not held this much carbon for at least 420,000 years according to data from ice cores. The recent increase in amounts of greenhouse gases such as carbon dioxide is having a significant impact on the warming of our planet.
Carbon moves through our planet over longer time scales as well. For example, over millions of years weathering of rocks on land can add carbon to surface water which eventually runs off to the ocean. Over long time scales, carbon is removed from seawater when the shells and bones of marine animals and plankton collect on the sea floor. These shells and bones are made of limestone, which contains carbon. When they are deposited on the sea floor, carbon is stored from the rest of the carbon cycle for some amount of time. The amount of limestone deposited in the ocean depends somewhat on the amount of warm, tropical, shallow oceans on the planet because this is where prolific limestone-producing organisms such as corals live. The carbon can be released back to the atmosphere if the limestone melts or is metamorphosed in a subduction zone.
