Front

What is a heterogeneous mixture?

Back

A heterogeneous mixture is a type of mixture where the components are not uniformly distributed, and different parts can be seen and separated, such as soup.

Front

What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture that has a uniform composition throughout, such as saltwater.

Front

What occurs at a divergent boundary?

Back

At a divergent boundary, tectonic plates move away from each other, leading to the formation of new crust.

Front

What type of electromagnetic wave has the longest wavelength?

Back

Radio waves have the longest wavelength and the lowest energy among electromagnetic waves.

Front

What part of the Earth receives direct sunlight year-round?

Back

The equator always receives direct sunlight.

Front

What is the Continental Drift Theory?

Back

The Continental Drift Theory states that all continents were once part of a supercontinent called Pangaea.

Front

What is the definition of tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact at their boundaries.

Front

What is the significance of the equator in terms of climate?

Back

The equator is significant because it receives direct sunlight, resulting in warmer temperatures and a tropical climate.

Front

What are the three types of plate boundaries?

Back

The three types of plate boundaries are divergent, convergent, and transform boundaries.

Front

What happens at a convergent boundary?

Back

At a convergent boundary, tectonic plates move towards each other, which can lead to the formation of mountains or subduction zones.
