SC.7.E.6.5 Lithosphere; Mantle : Hard

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the upper mantle.

Front

What causes earthquakes?

Back

Earthquakes are caused by the sudden release of energy in the Earth's crust due to tectonic plate movements.

Front

What is sea floor spreading?

Back

Sea floor spreading is the process by which new oceanic crust is formed at mid-ocean ridges and older crust is pushed away.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other.

Front

What is convection in the Earth's mantle?

Back

Convection in the Earth's mantle refers to the movement of molten rock due to heat, causing tectonic plates to move.

Front

What is a pluton?

Back

A pluton is a body of intrusive igneous rock that has solidified from magma beneath the Earth's surface.

Front

How do faults contribute to geological changes?

Back

Faults are fractures in the Earth's crust where blocks of rock have moved, often causing earthquakes and landform changes.

Front

What is erosion?

Back

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

Front

What is the significance of the Appalachian Mountains?

Back

The Appalachian Mountains are significant as they were formed by the collision and convergence of landmasses over millions of years.

Front

What role do volcanoes play in the lithosphere?

Back

Volcanoes are openings in the Earth's crust that allow magma to escape, contributing to the formation of new landforms.
