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 sea floor spreading?

Back

Sea floor spreading is caused by the movement of tectonic plates, where magma rises from the mantle to create new oceanic crust.

Front

What are convection currents?

Back

Convection currents are movements within the Earth's mantle caused by the heat from the core, which drives the movement of tectonic plates.

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. They can cause earthquakes and influence the formation of mountains.

Front

What is the significance of the Appalachian Mountains?

Back

The Appalachian Mountains were formed by the collision and merging of landmasses, showcasing the effects of tectonic activity over millions of years.

Front

What is the process of erosion?

Back

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

Front

What role do earthquakes play in shaping the Earth's surface?

Back

Earthquakes can cause sudden shifts in the Earth's crust, leading to the formation of new landforms and altering existing ones.

Front

What is the difference between oceanic and continental crust?

Back

Oceanic crust is thinner and denser than continental crust, which is thicker and less dense.

Front

What is tectonic plate movement?

Back

Tectonic plate movement refers to the shifting of the Earth's plates due to convection currents in the mantle, leading to geological activity.
