Human beings live and breathe in the ____________.

• Mesosphere

• Troposphere

• Exosphere

• Thermosphere

Barrie is located in this climate region

• Mackenzie District

• Atlantic Canada

• Northwestern Forest

• Great Lakes and St. Lawrence

"Hotspot" volcanoes occur

• on plate boundaries

• on fault lines

• in the middle of plates

• in trenches

The three types of rocks are:

• granite, basalt, and pumice
• marble, slate, and quartzite
• igneous, sedimentary, and metamorphic
• sandstone, shale, and limestone

What are seismic waves?

• Vibrations that travel through the Earth's layers

• Vibrations that travel through water
• Vibrations that travel through the air
• Vibrations that travel through space

How are earthquakes measured?

• Anemometer

• Barometer

• Seismographs
• Thermometers

What are convection currents?

• Circular motion of fluids caused by differences in pressure and viscosity in the core.

• The circular movement of the mantle as it transfers heat from the core to the crust.

• Linear motion of fluids caused by differences in temperature and density.
• Circular motion of solids caused by differences in temperature and density.

What are the four layers of the Earth?

• lithosphere, asthenosphere, mesosphere, endosphere
• crust, mantle, outer core, inner core
• troposphere, stratosphere, mesosphere, thermosphere
• crust, outer mantle, inner mantle, core

What did the hypothesis of continental drift suggest?

• The continents were once underwater and have since risen to the surface.
• The continents were once separate and have since come together.

• The continents were once stationary and have since started moving.
• The continents were once joined together and have since drifted apart.

What does the theory of plate tectonics propose?

• The theory of plate tectonics proposes that the Earth's lithosphere is stationary and does not move.
• The theory of plate tectonics proposes that the Earth's lithosphere is made up of only one large plate.
• The theory of plate tectonics proposes that the Earth's lithosphere is divided into several large and small plates that are stationary and do not interact with each other.
• The theory of plate tectonics proposes that the Earth's lithosphere is divided into several large and small plates that are constantly moving and interacting with each other.
