Scientists find trilobites during a routine dig. Trilobites were common in the Paleozoic Era (540 to 245 million years ago) and went extinct during the late Permian period (248 million years ago). On another site, the scientists find ammonites. Ammonites lived during the Mesozoic Era (245 to 65 million years ago) and are not found after that period. What can be concluded about the rock layers? Choose all that apply.
A The rock layers must have formed at the same time because they both contain biozones.
B The rock layer containing the trilobites must have formed before the one containing the ammonites.
C The rock layer containing the trilobites must have formed after the one containing the ammonites.
D The rock layers must have formed at different times because they contain two different biozones.
Answer:
A and C
Explanation:
The rock layers must have formed at different times because they contain two different biozones. The rock layer containing the trilobites must have formed before the one containing the ammonites. The key thing to note here is that the Trilobites only lived from 540 to 248 million years ago. And that the Ammonites were from 245 to 65 million years ago. So there's a 3 million year gap between these 2 different creatures where neither of them existed. So the dig where the trilobites were found has to be at least 3 million years older than the dig where the Ammonites were found. So with that in mind, let's look at the options and see what makes sense.
The rock layers must have formed at the same time because they both contain biozones. * This is nonsense no matter what dates you're speaking of. In effect it claims that all rocks that indicate life were created at the same time. So this is definitely a bad choice.
The rock layers must have formed at different times because they contain two different biozones. * This is technically incorrect since it assumes that all biozones represent an unique period of time which is incorrect. However, since the biozones represented by the presence of Trilobites and Ammonites don't overlap, it is true that these these rock layers were formed at different times. I would have preferred if this option said "non overlapping biozones". But on the balance, I'd consider this option to be true, so it should be selected.
The rock layer containing the trilobites must have formed before the one containing the ammonites. * This is definitely true since the last Trilobite died about 3 million years before the first Ammonite lived. So this is a correct choice.
The rock layer containing the trilobites must have formed after the one containing the ammonites.
* This is the opposite of the previous option. And since the previous option was true, this option must be false. So this is a bad choice
Which must be true for metamorphism to occur?
A. The parent rock must be in liquid form.
B. The parent rock must be igneous.
C. The process must take place underground.
D. The grain size must become smaller.
The parent rock must be in liquid form, must be true for metamorphism to occur. Hence, option A is correct.
What is parent rock?Parent rock is the fundamental rock that something else was produced from. It is mostly applied in the context of soil formation, where the parent rock typically has a significant impact on the final soil's composition.
Sandstone, shale, and limestone fall within this category. Metamorphic rock is the last type of parent rock. Extreme heat or pressure have resulted in the formation of metamorphic rocks. As a result, igneous or sedimentary rock changes in composition.
Thus, option A is correct.

Explain how scientific knowledge is developed when people make observations about the natural world.
Answer:
Scientific knowledge is developed only when you make an observation about the natural world because without an observation, you will not question anything which mean there will be no scientific knowledge about the world around us. Scientific knowledge is built as people come up with hypotheses and theories, repeatedly test them against observations of the natural world, and continue to refine those explanations based on new ideas and observations. Observation is essential to the process of science.

describe the difference in elevation and rock structure between a highland and a lowland
Answer:
High land is more eroded, lower land is less eroded.
Explanation:
highland has more erosion because the temperature is more on an extreme side, even though the rocks would be in well bigger pieces, in lowland there might be less elevation depending on the area, but the rocks would probably be a smaller size.
What Are the (2) most important climatic factors for the Indian people?
Answer:
Latitudinal Location and Distance from the Ocean/Sea.
Explanation:
Latitudinal Location because it is the distance from the equator. The farther away from the equator you get, the hotter it gets, and vice versa.
Distance from the ocean/sea because the ocean/sea is a heat reservoir. It stores heat, and lets it out when its cool, therefore making places near the sea have either colder or warmer temperatures depending on the time of year.

What are some advantages to an oligarchic form of government?
Answer:
Power is centralized within a leadership team, rather than involving everyone in every decision.
People can participate in activities, relationships, and work while the group in power handles the larger issues of the society.
An oligarchy strives to keep the status quo, which breeds conservatism instead of taking on risky ventures.
It can foster creativity and innovation because people are free from worries about running society.
Answer:
Oligarchy allows citizens to have the time to focus on their daily lives, more creative technologies to be created.
This is because oligarchy gives power to a group of experts which makes the government function properly .

A. The stratosphere is closest to the sun.
B. All layers of the atmosphere increase in temperature with altitude.
C. The air molecules are closer together in the upper stratosphere.
D. The ozone layer is found in the stratosphere
Answer:
D. The ozone layer is found in the stratosphere
Explanation:
Because warm air rises and cool air sinks, the troposphere is unstable. In the stratosphere, temperature increases with altitude. The stratosphere contains the ozone layer, which protects the planet from the Sun's harmful UV radiation.
In South China during the late Carboniferous period, was the air temperature warmer or cooler than the air temperature in the location today?
-Claim 1: It was warmer than it is today.
-Claim 2: It was cooler than it is today.
- Claim 3: No difference- the air temperature was the same as it is today.
Answer:
The correct option is:
1) It was warmer than it is today
Explanation:
Caboniferous period lasted from around 360 to 300 million years ago. The term Carboniferous means rich deposits of coal. The deposits of coals occured in different region of Europe, Asia and Africa, including South China. In the start of the period, the average temperate was 20°C° which was dropped to 12° in the middle of the period. This cooling and drying resulted in Carboniferous rainforest. Hence, the temperature was warmer than it is today.

O Both Newlands and Mendeleev arranged elements according to their atomic masses, but only Mendeleev used cherr
properties as well
Both Newlands and Mendeleev organized elements into groups, but only Newlands used a table with rows and column
Both Newlands and Mendeleev organized elements into a table with rows and columns, but only Mendeleev named
different groups of elements.
The correct answer is B. Both Newlands and Mendeleev arranged elements according to their atomic masses, but only Mendeleev used chemical properties as well.
Explanation:
Both John Newlands and Dmitri Mendeleev were relevant chemists, mainly known for designing the period table, which organized chemical elements. In the case of Newlands, he designed his period table around 1865 by organizing the known elements based on the atomic masses of elements (number of protons and neutrons); also, he divided elements into groups.
On the other hand, Mendeleev designed his periodic table around 1869; in this, elements were also arranged by their atomic masses, but Mendeleev considered the properties of each element such as electronegativity, which implied some minor changes in order, as well as leaving some spaces for elements that had not been discovered, but that Mendelev could predict. Thus, the option that compares the organization in both periodic tables is B.
Answer:
B. Both Newlands and Mendeleev arranged elements according to their atomic masses, but only Mendeleev used chemical properties as well.
