Briefly describe what Charles Darwin observed about the finches on the Galapagos island?

Answers

Answer 1
Answer: He observed that even though the finches had the same basic ancestry and while only living a handful of miles apart they had developed very specific beaks for their differing habitats. This is where most people view him as finding the basis for natural selection and evolution.

How does groundwater cause erosion and deposition?

Answers

Answer:

When acidic water soaks into the ground, water dissolves limestone, resulting in the formation of caves.

Explanation:

Final answer:

Groundwater causes erosion through hydraulic action and solution, leading to the formation of unique landforms.

Explanation:

Groundwater can cause erosion and deposition through two main processes: hydraulic action and solution.

ydraulic action occurs when the force of moving groundwater dislodges and carries away the particles of soil and rock. This can create channels and cavities, causing erosion.

Solution happens when groundwater dissolves certain minerals and rocks, such as limestone, leaving behind deposits.

For example, when groundwater flows through a limestone cave, it can dissolve the rock, leading to the formation of stalactites and stalagmites.

These are formed through the deposition of dissolved minerals from the water.

In summary, groundwater can erode and deposit material through hydraulic action and solution, shaping the landscape and creating unique landforms.

Regarding the area labeled B, which best describes the characteristics of the ocean current in this location? A. warm, high salinity, and dense waters B. cold, high salinity, and denser waters C. warm, low salinity, and less dense waters D. cold, low salinity, and dense waters

Answers

Regarding the area labeled B, cold, low salinity, and dense waters are the best describes the characteristics of the ocean current in this location. Thus, option (b) is correct.

What is ocean?

The greatest area on earth is referred to as the "ocean." The ocean's 71% slat water has a light blue appearance. The motion of water waves is the ocean. Magnesium, calcium, and chlorine are abundant in the ocean. The ocean covers the large surface area of the Earth.

According to the characteristics of the ocean current as the given, the image was on the described. There are the based as the blue line was on, they indicate the current location. There are the cold and the low salinity, and the dense of the water. There are the labeled on the cold and the lower ocean in the location.

As a result, the area labeled B, cold, low salinity, and dense waters are the best describes the characteristics of the ocean current in this location. Therefore, option (b) is correct.

Which is a result of the emission from the use of fossil fuel​

Answers

Answer:

increase in sea levels

Explanation:

Just did this on A P E X

Answer:

Emission from fossil fuels can cause a lot of toxic air pollution. The air pollution can lead to an increase in respiratory diseases such as lung disease and lung cancer. Sulfur dioxide (SO2), for example, is emitted from burning coal and leads to an increase in acid rain. These are just a few examples of the harmful effects of fossil fuels.

Explain on a complete sentence why it is important for scientific to share information whit one another

Answers

Good Morning! From the beginning of science it has been understood that different experiments bring different results. The sharing of information, in this sense, acts on the contribution of accumulated knowledge to the subsequent production of new discoveries and innovations. Think of it this way: if the individual who created the ways of storing energy had not provided and shared his invention, would it be possible for the inventor, for example, from the radios to the pile to have succeeded? This small example illustrates the fundamental relationship between the various researches and discoveries, revealing the importance of information sharing, which also contributes to the improvement. Hugs!

Scientists share information with one another so that results can be replicated and used to develop scientific knowledge.

This is the correct answer, on e2020 at least. Hope this helps!

the top of mount everest is at about 8,850 m. What would the approximate air temperature be at that altitude?

Answers

If we speak mathematically how the temperature decreases with the altitude than the temperature at Mount Everest should be -86.73 C degrees given that the temperature at zero altitude is 0 C degrees. This is a result of the estimated temperature decrease which comes to 9.8 C degrees drop on every 1,000 meters or 0.98 per every 100 meters eliviation. So 8,850 of altitude by 0.98 C degrees decrease on every 100 meters comes to -86.73 degrees, still keep in mind that this is only if the temperature at 0 altitude is 0 C degrees and that it is only a mathematical estimate under certain conditions, in practice it is much different.

At the summit, the temperature can be 100°F below zero. But on a good summit day, a climber can expect around -15°F
