What are landforms?
Natural features of the Earth’s surface, such as mountains, valleys, and plains.
True or False: Tectonic plates are rigid sections of the Earth’s lithosphere that move and interact.
True
Fill in the blank: The process by which rocks and soil are worn away and transported is called __________.
erosion
What is the primary cause of tectonic activity?
The movement of tectonic plates due to convection currents in the mantle.
Multiple Choice: Which of the following is NOT a type of landform? A) Mountain B) River C) Glacier D) Cloud
D) Cloud
What is the term for the boundary where two tectonic plates meet?
Plate boundary
True or False: Erosion only occurs due to water.
False
What are tides?
The regular rise and fall of sea levels caused by the gravitational pull of the moon and sun.
Fill in the blank: __________ erosion occurs when wind blows sand and dust away from the surface.
Wind
Multiple Choice: Which type of plate boundary is associated with earthquakes? A) Divergent B) Convergent C) Conservative D) All of the above
D) All of the above
A landform created at the mouth of a river where sediment is deposited as the river meets a larger body of water.
True or False: Erosion can lead to the formation of canyons.
True
What is the process of sediment being dropped in a new location called?
Deposition
Fill in the blank: The __________ is the layer of the Earth where tectonic plates float.
asthenosphere
Multiple Choice: Which landform is formed primarily by volcanic activity? A) Canyon B) Mountain C) Volcano D) River
C) Volcano
What role do tides play in coastal erosion?
Tides can increase the rate of erosion by constantly changing water levels and wave action along shorelines.
True or False: Glaciers can cause erosion by scraping the land as they move.
True
What is an earthquake?
A sudden shaking of the ground caused by the movement of tectonic plates.
Fill in the blank: The __________ effect is responsible for the circular movement of ocean currents.
Coriolis
