What is an example of a geological event?

• Tsunami

• Earthquake

• Volcano Erupting

• All of these answers are geological events.

How are tsunamis formed?

• The ocean is heated by the Sun and expands the water.

• An underwater disruption such as an earthquake.

• Something large forcing the water onto shore.

• Unusual tides

What is the most common cause of an earthquake?

• Unusual movement of the Earth's tectonic plates.

• Volcanoes erupting shake the Earth's surface.

• Cracks in the Earth's surface (called fault lines) move and break under stress casuing vibrations.

• Tsunamis

What is drought?

• An area that typically does not receive much rainfall.

• An area receiving an unusually low amount of rainfall for a long period of time.

• When it rains a lot.

Which is NOT a part of a volcano?

• Nitrogen

• Magma

• Lava

• Ash

• Crater

Where is an earthquake most likely to happen?

• Near the ocean

• Along the edge of tectonic plates

• Near the equator

What is the Richter scale?

• It shows the temperature of the ocean.

• It measures the pressure of a volcano.

• It measures the strength of an earthquake.

• It measures how rich somebody is.

Cyclones happen in the tropical regions of Australia.

• True

• False

When can a volcano be classified as extinct?

• When the volcano is cut off from its magma supply.

• It has become cold on the inside.

• The top of the volcano is sealed over.

• Water from rainfall fills the inside of the volcano so it can no longer erupt.
