Multiple Choice

An example of a gradual change in the Earth is:

• Earthquakes

• Volcano eruptions

• Erosion

• None of the above.

Multiple Choice

The layer of the Earth in which we find ALL living things is:

• The inner core

• The outer core

• The mantle

• The crust

Multiple Choice

An earthquake in Japan registers on a seismograph in Winnipeg, Manitoba. This occurs because

• seismographs anywhere will record all earthquakes

• the Earth's crust is solid, allowing the surface waves to be recorded anywhere.

• seismic waves travel through all the layers of the Earth.

• the core of the Earth is liquid.

Multiple Choice

In 1935 Charles Richter developed a scale that helped geologists understand about the strength or magnitude (intensity) of an earthquake. The scale he developed starts at 0 and each increase of 1 indicates an increase of 10 times the amount of

• damage

• seismic waves

• ground movement

• fault movement

Multiple Choice

Minerals can be identified by certain clues. The clue that identifies the color of the powdered form of the mineral left behind when it is rubbed against a rough surface is called its

• streak

• lustre

• colour

• cleavage

Multiple Choice

Allison and Rachel were investigating the banks of the river and discovered a large section had been eroded away. They could see layers of different soil types. These visible layers are called

• cementation

• sedimentation

• calcification

• stratification

Multiple Choice

Metamorphic rock is rock that has changed form. Is it usually formed

• below the Earth's surface

• on the Earth's surface

• when rock is heated

• when rock is cooled.

Multiple Choice

Which of the following phenomenon are typically responsible for weathering, erosion, and deposition.
