Forces that Shape Earth - Study Jam

Front

What is isostasy?

Back

Isostasy is the equilibrium between the continental crust and the denser mantle below, where the crust floats on the mantle.

What does 'no stress' mean in geological terms?

Back

'No stress' refers to a state where there are no forces acting on a material, meaning it is not being compressed, pulled apart, or sheared.

Front

What is uplift in geology?

Back

Uplift is the upward vertical motion of Earth's surface, often caused by tectonic forces.

Front

What is tension in the context of forces?

Back

Tension is a pulling apart force that stretches materials.

Front

What was Pangaea?

Back

Pangaea was a supercontinent that existed over 200 million years ago, where all the continents were joined together.

Front

What is compression in geological terms?

Back

Compression is a force that pushes materials together, often leading to the formation of mountains.

Front

What is shear stress?

Back

Shear stress is a force that causes parts of a material to slide past each other, often resulting in deformation.

Front

What is the role of tectonic plates?

Back

Tectonic plates are large sections of Earth's crust that move and interact, causing geological events like earthquakes and volcanic eruptions.

Front

What is the difference between continental crust and oceanic crust?

Back

Continental crust is thicker and less dense than oceanic crust, which is thinner and denser.

Front

What is subsidence?

Back

Subsidence is the sinking or settling of the Earth's surface, often due to the removal of underground support.
