Explain how scientific knowledge is developed when people make observations about the natural world.

Answers

Answer 1
We typically think of observations as having been seen "with our own eyes," but in science, observations can take many forms. Of course, we can make observations directly by seeing, feeling, hearing, and smelling, but we can also extend and refine our basic senses with tools: thermometers, microscopes, telescopes, radar, radiation sensors, X-ray crystallography, mass spectroscopy, etc. And these tools do a better job of observing than we can! Further, humans cannot directly sense many of the phenomena that science investigates (no amount of staring at this computer screen will ever let you see the atoms that make it up or the UV radiation that it emits), and in such cases, we must rely on indirect observations facilitated by tools. Through these tools, we can make many more observations much more precisely than those our basic senses are equipped to handle.

Tools like the Hubble Space Telescope, microscopes and submersibles help us to observe the natural world.

Observations yield what scientists call data. Whether the observation is an experimental result, radiation measurements taken from an orbiting satellite, an infrared recording of a volcanic eruption, or just noticing that a certain bird species always thumps the ground with its foot while foraging — they're all data. Scientists analyze and interpret data in order to figure out how those data inform their hypotheses and theories. Do they support one idea over others, help refute an idea, or suggest an entirely new explanation? Though data may seem complex and be represented by detailed graphs or complex statistical analyses, it's important to remember that, at the most basic level, they are simply observations.
Observations inspire, lend support to, and help refute scientific hypotheses and theories. However, theories and hypotheses (the fundamental structures of scientific knowledge) cannot be directly read off of nature. A falling ball (no matter how detailed our observations of it may be) does not directly tell us how gravity works, and collecting observations of all the different finch species of the Galapagos Islands does not directly tell us how their beaks evolved. 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, but it is only half the picture.
Answer 2

Answer:

Scientific knowledge is developed when people make observations about the natural world. An observation may generate a scientific question, which may lead to a hypothesis. The hypothesis can be tested through experimentation. The results of the experimentation may lead to changes in scientific knowledge.

(If two people answer, the first one to answer the question correctly will get brainliest.)

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

Answers

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.

What Are the (2) most important climatic factors for the Indian people?​

Answers

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.

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.

Answers

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.

Explanation:

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.

Answers

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

The 31 acres of water at the docks were later used by ships from the Union Castle Line, Ellerman Line, Blue Star Line and Ben Line. In the 1920s, new facilities were built for the handling of frozen meat. The export dock was badly bombed during the Second World War and filled-in. The docks closed in 1967.
