Geoscience Semester I Final Review

Front

What is the process called when two tectonic plates collide and create mountains?

Back

Convergence

Front

What describes the relationship between isotopes of the same element?

Back

Isotopes have the same number of protons but different numbers of neutrons.

Front

What happens when a continental plate and an oceanic plate converge?

Back

The oceanic plate will subduct beneath the continental plate, leading to volcanic activity and the formation of a mountain range.

Front

How does a neutral atom become a positively charged ion?

Back

By losing electrons.

Front

What is the remnant called after a supernova explosion of a massive star?

Back

Neutron star / Black Hole.

Front

What is subduction in plate tectonics?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle.

Front

What is the difference between a neutron star and a black hole?

Back

A neutron star is a dense remnant of a supernova, while a black hole is a region of space where gravity is so strong that nothing can escape.

Front

What is the definition of tectonic plates?

Back

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

Front

What is the significance of the mid-ocean ridge?

Back

The mid-ocean ridge is a continuous mountain range formed by plate tectonics, where new oceanic crust is created.

Front

What is the role of convection currents in the Earth's mantle?

Back

Convection currents in the mantle drive the movement of tectonic plates.
