In this lesson, we are going to be learning about why tectonic plates move, what an earthquake is and why they occur.

Quiz:

Intro quiz - Recap from previous lesson

Before we start this lesson, let’s see what you can remember from this topic. Here’s a quick quiz!

Q1.An active volcano has had at least one eruption in the last 10,000 years.

True False

1/4

Q2.Volcanoes are formed… (choose two options)

Select two (2) boxes

when tectonic plates move around each other.. when tectonic plates collide and one plate is pushed beneath another. when tectonic plates remain still. when tectonic plates move away from one another.

2/4

Q3.Which of these describes a Stratovolcano?

Lava does not flow as far. Many layers of hardened lava build up a steep volcano after repeated eruptions. Lava flows easily so a broad volcanic mountain is built up over time by repeated eruptions.

3/4

Q4.Which of these describes a shield volcano?

Lava does not flow as far. Many layers of hardened lava build up a steep volcano after repeated eruptions. Lava flows easily so a broad volcanic mountain is built up over time by repeated eruptions.
