What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's crust that move and interact with each other, causing geological activity such as earthquakes and the formation of mountains.

Front

What is the difference between convergent and divergent tectonic plates?

Back

Convergent plates move towards each other, often causing one plate to be forced below another, while divergent plates move apart from each other, creating new crust.

Front

What is the composition of Earth's crust?

Back

Earth's crust is primarily composed of rocks and minerals, including silicates, which are made up of silicon and oxygen.

Front

What happens to particles in a solid?

Back

Particles in a solid vibrate side to side and are tightly packed together, which gives solids a definite shape and volume.

Front

What are the subatomic particles found in the nucleus of an atom?

Back

The nucleus of an atom contains protons, which are positively charged, and neutrons, which have no charge.

Front

What role does gravity play in the formation of the Solar System?

Back

Gravity caused surrounding dust grains to collide and stick together, forming larger bodies that eventually became planets.

Front

Which planet has a lower gravitational pull than Earth?

Back

Uranus has a lower gravitational pull than Earth, meaning you would weigh less on Uranus.

Front

What is the definition of gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

What is the significance of the Himalaya Mountains in tectonic activity?

Back

The Himalaya Mountains are formed by the collision of two convergent continental plates, which causes uplift and geological activity.

Front

How do scientists study tectonic plate movements?

Back

Scientists use seismographs to measure earthquakes and GPS technology to track the movement of tectonic plates.
