I think the Arctic tundra is the coldest.
In the early 1900s, France, Spain, Great Britain, Japan, and the U.S., which claimed Pacific colonies, controlled most of the Pacific islands. Thank you
Plate tectonics are important to geoloigists because they explain how the continents make up the earths crust.
Answer:
The correct answer is A. Barrier islands are constantly moving in the direction of the longshore drift.
Explanation:
Barrier islands are islands in the form of relatively narrow strips of sand located close to and parallel to the coast of the mainland. As a rule, they are located in the form of a chain consisting of several islands, sometimes more than a dozen. The length and width of the barrier islands are related to coastal parameters, including tides, wave energy, sea level and soil composition. Some barrier islands reach a length of more than one hundred kilometers, the longest and widest is Padre Island, Texas. The shape, area and the very existence of barrier islands are variable, as they can appear and disappear in a short time on a geological scale.
These islands are formed from the longshore drift, which is forming these islands by sediment and sand accumulation. Therefore, as they are formed by this process, it is the same process that constantly moves them.
The Earth's mantle is very important. It is important for the Earth's crust evolution, as well as being the provider of thermal and mechanical forces for plate tectonics. The mantle is what covers the most part of Earth inside if it is not there, then the heat of the core will burn the Earth's crust. And the mantle does make up 84% of Earth's volume, so that wouldn't be good!
