What is convection?

Back

Convection is the process of heat transfer in fluids (liquids and gases) where warmer, less dense material rises, and cooler, denser material sinks, creating a circular motion.

Front

What is a divergent plate boundary?

Back

A divergent plate boundary is a tectonic boundary where two tectonic plates move away from each other, leading to the formation of new lithosphere, often associated with seafloor spreading.

Front

What is the B horizon in soil?

Back

The B horizon, also known as the subsoil, is a soil layer characterized by the accumulation of minerals like clay, iron, and aluminum, which leach down from the upper layers.

Front

What are tectonic plates?

Back

Tectonic plates are large, rigid pieces of the Earth's lithosphere that move and interact with one another, causing geological phenomena such as earthquakes and volcanic activity.

Front

What is subduction?

Back

Subduction is the geological process where one tectonic plate moves under another plate and sinks into the mantle, often occurring at convergent plate boundaries.

Front

What is conduction?

Back

Conduction is the transfer of heat through a material without the movement of the material itself, occurring mainly in solids.

Front

What is radiation in the context of heat transfer?

Back

Radiation is the transfer of heat in the form of electromagnetic waves, such as infrared radiation, which can occur in a vacuum.

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is a tectonic boundary where two plates collide, leading to subduction or mountain building.

Front

What is a transform plate boundary?

Back

A transform plate boundary is a tectonic boundary where two plates slide past each other horizontally, causing earthquakes.

Front

What is seafloor spreading?

Back

Seafloor spreading is the process by which new oceanic crust is created at mid-ocean ridges as tectonic plates pull apart.
