The column of mercury in the barometer is lowest when the barometer is ion location 4. Atmospheric pressure measured by the barometer decreases with an increase in altitude. Atmospheric pressure is caused by the column of air above the ground level at any given point on the earths surface thus an increase in altitude leads to a decrease in this column leading to a decrease in atmospheric pressure.
Answer:
Hi, so the Great Plains are made of sedimentary rock and were subducted and melted to magma which cooled to igneous rock, was uplifted and then formed the Rocky Mountains.
Explanation:
Basically it melted then cooled into igneous rock then was lifted and formed the rocky mountains!

Structure is a better indicator of shared ancestry than function. When species share the same structure despite not needing similar structures functionally, it shows that there was almost definitely a common ancestor.
Constants never change.
Controls typically don't change or they are done by standard means
(like in an experiment where you water plants with sodas, the plant you use water with is the control)
Dependent variables are the outcome of the experiment. This is the result of changing something.
Independent variables are what you are testing. A independent variable is something that is intentionally altered.
easy way to remember it is that dependent variables depend on what other variables are. so you cant change a dependent variable, but you can change the other variables.
Answer:
B. Air moves towards the poles as it cools
Explanation:
The image represent convection cell or Hadley cell is a natural phenomenon in the atmosphere that occur due to difference in the density within a body of liquid or gas. These differences in density causes rise and fall in currents.
The process in step A refers to when hot air moves up and in the step B, the hot air encounters a cold surface, it direct exchange the heat with cold surface and the air cools down and move towards the poles.
Hence, the correct answer is "B. Air moves towards the poles as it cools".
