Answer:
1. Tectonic movement
2. Erosion
3. Volcanic eruptions
4. Glaciation
Step-by-step explanation:
✔️ Tectonic movement: This describes the movements of the earth lithosphere - solid rock over a geologic time. Seismic activities (like earthquakes) is most associated with tectonic. When the tectonic plates move, their jagged edges actually slip out and then it causes earthquake.
✔️ Volcanic eruptions: These are explosive or effusive eruption of molten magma which comes from the earth's mantle and forms on the earth surface as lava. When the eruptions occur, a combination of silica and dissolved gas are formed which determine the type of eruption and shape of volcano.
✔️ Erosion: This is the process whereby rock, sediment and soil are carried away by agents of erosion. This physical process changes the landform, loss of soil and the damage of ecosystem.
✔️ Glaciation: Glacial actions have shaped much of the landscape in the arctic and sub-artic regions. Glaciers are usually eroded through the process of plucking and abrasion. During the plucking process, glacier flows over bedrock and softens the blocks of rock that were brought into the ice.
