2-3 Earth's Formations Review

Front

What is coastal erosion?

Back

Coastal erosion is the breakdown and removal of land along the coastline due to the action of waves, currents, and tides.

Front

What are divergent boundaries?

Back

Divergent boundaries are tectonic plate boundaries where two plates move away from each other, often resulting in the formation of new crust, such as mid-ocean ridges.

Front

What is the theory of Plate Tectonics?

Back

The theory of Plate Tectonics states that the Earth's lithosphere is divided into tectonic plates that float on the semi-fluid asthenosphere and move slowly over time.

Front

What geological feature is formed at divergent boundaries?

Back

Mid-ocean ridges are formed at divergent boundaries where tectonic plates move apart.

Front

Where does volcanic activity typically occur at convergent boundaries?

Back

Most volcanic activity at convergent boundaries occurs along the continental margins, where an oceanic plate subducts beneath a continental plate.

Front

What is mass-wasting?

Back

Mass-wasting refers to the movement of soil and rock down a slope due to gravity, which can occur rapidly or slowly.

Front

What are convergent boundaries?

Back

Convergent boundaries are tectonic plate boundaries where two plates collide, leading to subduction or mountain formation.

Front

What is tectonic uplift?

Back

Tectonic uplift is the process by which the Earth's crust is raised due to tectonic forces, often resulting in the formation of mountains.

Front

What is erosion?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface and transported to another location by natural forces such as wind or water.

Front

What is the asthenosphere?

Back

The asthenosphere is a semi-fluid layer of the Earth's mantle located beneath the lithosphere, allowing tectonic plates to move.
