Answer: they are based on important events happened in earth’s history
Explanation:
Answer:
The action of the internal Earth forces results in the formation of constantly moving tectonic pates, causing constant formation and destruction of landforms.
Explanation:
Earth is an active planet. It has a core that is active and very hot, and the inner part of it influences the outer part of it. The outer core further heats up the mantle layer which is located below the crust. The mantle layer has a process called convection currents which occurs because of the difference in heat and pressure on the top and bottom parts of it.
The convection currents are what causes the internal Earth forces like the immense pressure and magma pushing through the crust. They are so powerful that they are responsible for cracking up the crust and forming numerous tectonic plates. They also manage to move the plates on Earth's surface, causing different types of interactions between them, which in turn results in the constant formation of landforms on one side and constant destruction on another side.
Explanation:
balance of trade, the difference in value over a period of time between a country's imports and exports of goods and services, usually expressed in the unit of currency of a particular country or economic union (e.g., dollars for the United States, pounds sterling for the United Kingdom).
