Earthquakes (Manolo 4 - SS Q4)

Earth's crust is made up of huge slabs of solid rock called _______________, that are always in motion.

• Plates

• Faults

There are breaks or cracks where these plates come together. These cracks are called _______________.

• Plates

• Faults

In some places, Earth's plates can slide slowly past each other along a fault. In other places, plates can push together, move under or over each other, or even move apart from each other.

• True

• False

In some places, Earth's plates can slide slowly past each other along a fault. In other places, plates can push together, move under or over each other, or even move apart from each other. This type of plate movement causes ______________ to occur.

• earthquakes

• fires

These are movements in Earth's crust that are caused by a sudden shift of Earth's plates.

• Earthquakes

• Fires

• Drought

• Hailstorm

Explain how earthquakes occur.

Answer explanation

The constant movement of Earth's plates put stress on rock that is on both sides of a fault. As plates grind against each other, energy builds up in these rocks. When this energy is released, the crust shakes, vibrations reach Earth's surface, and an earth occurs.

This is an area where many earthquakes occur. This fault line sits between a continental and oceanic boundary.

• The San Andreas Fault

• The Philippine Fault Zone

• Juan de Fuca Plate

Most earthquakes happen along the edges of ocean and continental plate boundaries.

• True

• False

There is an area around the Pacific Ocean where a number of Earth's plates meet. This area is known as the "________________".

• Ring of Fire

• Ring of Earthquakes

• Ring of Plates

• Fault lines

How did the Pacific Ring of Fire get it's name?

• Because many earthquakes and volcanic eruptions occur here

• Because it's very hot here

• Because it's shaped like a ring
