Pangea and Plate Tec #2

Most geologists think that the movement of Earth’s plates is caused by _______

• convection.

• continental drift.

• subduction.

• conduction.

The place where two plates come together is known as a _______

• transform boundary.

• divergent boundary.

• convergent boundary.

• rift valley.

Below is a picture of sea-floor spreading. How are the ocean crusts moving?

• Converging

• Diverging

• Sliding

• No movement

What type of event will occur at this boundary?

• Earthquake

• Volcano Eruption

• Tornado

• Mountain Building

What is evidence for Pangea?

• Fossils of plants and animal found on different continents.

• Rock formations found on many different continents.

• The continents look like puzzle pieces.

• The magnetic field.

The thin, solid, outermost layer of Earth; made of less dense silicates and is either continental (landmasses) or oceanic (ocean floors)

• mantle

• crust

• pangea

• earthquake

What is Plate Tectonics?

• movement of the Earth in space

• movement of the oceans against Earth's land

• movement of the Earth around the sun

• movement of the pieces of Earth's crust

What is represented by the picture? 

• Sea-floor spreading
• Pangea
• How the continents are arranged today
• Volcanoes

Which piece of evidence was use to prove continental drift?

• The shape of the continents
• Similar fossils found on separate continents
• Tree fossils found in odd places
• All of the above

This piece of evidence that Alfred Wegener used to prove the continents were once connected involved finding remains of once-living organisms on different continents.

• jigsaw evidence

• fossil evidence

• rock evidence
