Science 8 - Quarter 2

It is caused by shaking or trembling caused by the sudden release of energy.

• Earthquake

• Volcano

• Typhoon

• Tsunami

• Landslide

Answer explanation

It occur when rocks along a fault suddenly move.

It is a force that squeezes a rocks together, stretches or pulls them apart, or pushes them in different directions.

• Epicenter

• Seismic Waves

• Stress

• Fault

• Focus

Answer explanation

As tectonic plates move, they cause stress in the crust, which in turn produces faults and folds.

It is a break in the Earth's crust along which significant movement has taken place.

• Epicenter

• Seismic Waves

• Stress

• Fault

• Focus

It forms as a result of tension.

• Normal Fault

• Fault

• Reverse Fault

• Strike-Slip Fault

Answer explanation

The rock layers in the Earth's crust are pulled apart, and gravity causes one section to move downward in relation to the other.

It forms as a result of compression.

• Normal Fault

• Fault

• Reverse Fault

• Strike-Slip Fault

Answer explanation

The rock layers in the Earth's crust are squeezed together, and the force pushes one section upward in relation to the other.

It forms when the rock layers on opposite sides of a fault slides past each other horizontally.

• Normal Fault

• Fault

• Reverse Fault

• Strike-Slip Fault

Answer explanation

This type of fault is sometimes called as tear, wrench or transcurrent fault.

What are the three types of fault?

• Tension Fault, Compression Fault, Shearing Fault

• Normal Fault,

  Reverse Fault, Strike-Slip Fault

• Normal Fault,

  Reverse Fault,

  Compression Fault,

• Normal Fault,

  Tension Fault,

  Shearing Fault

How do faults produce earthquakes?

• Energy from inside the Earth make the ground move.

• Doing nothing

  produce earthquakes

• Jumping on the ground produce earthquakes.

• All of the above

Answer explanation

Every time a FAULT slips or moves, it's EARTHQUAKE

Where does an earthquakes start?

• Epicenter

• Seismic Waves

• Stress

• Fault

• Focus

It is the place where the first break happens, where the fault starts to slip, where first movement takes place.

• Epicenter

• Seismic Waves

• Stress

• Fault

• Focus

Answer explanation

It is the starting point of the earthquake.
