Geoscience Final Review

Front

What is a Transform Boundary?

Back

A tectonic plate boundary where plates slide past one another, causing earthquakes and valleys without creating or destroying lithosphere.

Front

What is Seafloor Spreading?

Back

The process by which new oceanic lithosphere forms as magma rises to Earth's surface and solidifies at a mid-ocean ridge.

Front

Define Weathering.

Back

The process by which large rocks are broken down into smaller parts due to environmental factors.

Front

What is the life cycle of the Sun?

Back

The correct order is: nebula, fusion stage, red giant, white dwarf, black dwarf.

Front

What is the nucleus of an atom?

Back

The central region of an atom, containing protons and neutrons.

Front

What occurs at a Convergent Boundary?

Back

Tectonic plates move towards each other, often causing one plate to be forced beneath another, leading to subduction.

Front

What is a Divergent Boundary?

Back

A tectonic plate boundary where plates move apart from each other, leading to the formation of new crust.

Front

Explain Erosion.

Back

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

Front

What is Plate Tectonics?

Back

The theory that explains the movement of the Earth's lithosphere which is divided into tectonic plates.

Front

What is a Black Dwarf?

Back

A theoretical stellar remnant that occurs after a white dwarf has cooled and no longer emits significant heat or light.
