Compression and erosion of rocks are responsible for the creation of

The correct answer is - landscapes.

Both the compression and the erosion are processes that contribute to the shape and form of the landscape. They are different from one another and create different types of landscape forms. The compression is the one that creates hills, mountain ranges, highlands, and it does that by creating a lot of pressure on the land which gradually lifts it upwards. The erosion, on the other hand, is a process that has the opposite effect. The erosion has a tendency to flatten the landscape. It moves away the sediments broken down by the weathering and gradually makes the landscape flatter. Also it creates numerous interesting shapes in the nature, especially on the places where the wind and the water are the ones responsible for the erosion.

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above

c- cold periods in earth's history during which glaciers covered much of the surface.
