The type of boundary where two tectonic plates move towards each other.

What is convergent boundary?

100

The outer, lighter, solid layer of the lithosphere.

What is the crust?

100

The type of boundary most often responsible for earthquakes.

What is a transform boundary?

100

A region around much of the rim of the Pacific Ocean where many volcanic eruptions and earthquakes occur.

What is the Ring of Fire?
100

These rocks that show ancient animals living on distantly located continents, that once in history were connected.

What are fossils?

200

The type of boundary where two tectonic plates move away from each other.

What is divergent boundary?

200

The hot, liquid, melted rock that supports the lithosphere.

What is the asthenosphere?

200

Volcanoes are formed at this type of boundary.

What is convergent?

200

This type of natural disaster is common in the capital city of Haiti, Port-au-Prince, which lies close to a transform boundary between the Caribbean and North American plates.  

What is an earthquake?

200

Rocks at these featuress are tested as younger than rocks at places like the Appalachian Mountains.

What are mid-ocean ridges?

300

The type of boundary where two tectonic plates slide parallel to each other.

What is transform boundary?

300

The solid metal sphere at the center of the earth?

What is the inner core?

300

Volcanoes are caused by this type of plate meeting a continental plate.

What is an oceanic plate?

300

Iceland is unique because it is very volcanically active, but often at low elevation with rift valleys. This type of plate boundary exists here.

What is divergent?

300

Satellite measurements of Mt Everest show the mountain doing this by 2 cm every year.

What is getting taller?

400

The name for when an oceanic plate is forced underneath a continental plate at a convergent boundary.

What is subduction?

400

The hot, liquid rock, part of the earth that has convection currents.

What is the mantle?

400

Mountain ranges in the ocean are caused by this phenomenon, lava rising up at a divergent boundary.

What is seafloor spreading?

400

California's San Andreas fault experiences many earthquakes, meaning the plates are forming this type of boundary.

What is transform?

400

This about the South American and African continents show they were connected once long ago.

What is the shape?

500

The name for where the rock breaks or shifts at a plate boundary.

What is a fault?

500

The layer of the earth that the tectonic plates are a part of.

What is the crust?

500

Mountain ranges that do not have active volcanoes are found at a continental-continental convergent boundary with this phenomenon.

What is tectonic uplift?

500

The Himalayan mountain range and Tibetan plateau have formed as a result of the collision between these two plates.

What is Indian and Eurasian?

500

Convection currents rise because warmer material at the bottom gets less dense.  Evidence that convection currents could exist in the mantle is based on the evidence that metal and rock near the core has a high this.

What is temperature?
