Waves carry out abrasion of coastal rock by transporting and grinding sediment particles against the rock surface, causing erosion and wearing down of the rock over time.

The energy of the waves, combined with the sediment load, determines the rate of abrasion. In the surf zone, where waves break onto the beach, the rate of abrasion can be high due to the turbulence and energy of the breaking waves. This area experiences intense wave impact and the grinding action of sediment can lead to rapid erosion of the coastline. However, abrasion rates can vary depending on factors such as wave energy, sediment load, and rock hardness. In other coastal settings, such as rocky cliffs or offshore reefs, the rate of abrasion may be slower due to lower wave energy or the presence of protective features, such as boulder fields or vegetation.

The rate of deformation and the temperature are determining factors for whether a rock deforms in a brittle or ductile fashion.

The manner in which a rock deforms, whether brittle or ductile, depends on the rate of deformation and the temperature conditions. At low temperatures and high rates of deformation, rocks tend to deform in a brittle manner, undergoing fracturing and faulting. This is because the stresses exceed the rock's ability to undergo plastic deformation.

On the other hand, at higher temperatures and lower rates of deformation, rocks exhibit ductile behavior, undergoing plastic deformation through processes like folding and stretching. This is because elevated temperatures allow the rock to undergo internal rearrangement of atoms and exhibit greater flexibility. Therefore, the interplay between temperature and deformation rate determines whether a rock will deform in a brittle or ductile fashion.

On the eastern side of mountains in Oregon and Washington in the western United States, the air tends to be drier and colder compared to the western side. This is because as the moisture-laden air from the Pacific Ocean rises and cools, it releases its moisture as precipitation on the western side of the mountains.

This process is called orographic lifting. By the time the air reaches the eastern side, it has lost much of its moisture, and as it descends, it warms and dries out even more due to the adiabatic heating process.

This phenomenon results in a stark difference in climate between the western and eastern sides of the mountains. The western side is characterized by a temperate maritime climate with mild, wet winters and cool, dry summers. In contrast, the eastern side has a semi-arid to arid climate with hot, dry summers and cold, dry winters. This climate difference also influences the vegetation and wildlife in the two regions, with the western side having lush forests and abundant wildlife, while the eastern side has sparse grasslands and desert vegetation.

Earth once consisted of a single large landmass and one ocean. The landmass is named Pangaea.

It is believed to have formed about 300 million years ago during the Paleozoic Era and began to break apart around 200 million years ago in the Mesozoic Era. Pangaea was surrounded by a single large ocean called Panthalassa.

The formation of Pangaea was a result of plate tectonics, the movement of large plates of the Earth's lithosphere. The continents we see today are not fixed but rather constantly moving due to the shifting of tectonic plates.

This movement is responsible for the creation of mountains, volcanoes, and earthquakes, as well as the separation and collision of continents.

As the plates moved and collided, Pangaea began to break apart and separate into smaller continents that we know today. This process is still ongoing, and the continents are continuing to drift apart at a rate of a few centimeters per year.

The separation of the continents had a profound impact on the Earth's ecosystems, climate, and geological processes.

It allowed for the development of new species and habitats, and the opening and closing of oceanic gateways influenced the circulation of the oceans and the climate of the planet.
