Tectonic plates

Describe the most likely relationship between these mountains and nearby tectonic plates.

• The mountains are probably formed by earthquakes

• The mountains are probably formed by the movement of glaciers

• The mountains are probably located near the edge of 2 tectonic plates.

• The mountains are probably formed by running water.

Is there a pattern to the locations of earthquakes and volcanoes around the globe?

• No, earthquakes and volcanoes are random.

• Yes, earthquakes and volcanoes usually occur near the boundaries of tectonic plates.

• yes, earthquakes and volcanoes usually occur in the middle of tectonic plates.

• No, earthquakes and volcanoes usually occur under water.

The Ring of Fire is an area where a large number of earthquakes and volcanic eruptions occur. What claim can be made about the Ring of Fire from this information?

• It is the only place on Earth where earthquakes can happen.

• The edges of the tectonic plates are moving in this area.

• It represents the areas where tectonic plates are the thickest.

• It has been getting larger since Earth first formed.

A force caused the continents to drift apart over time. Once scientists figured out what that force was, the theory of plate tectonics was born! The image above shows what Geologists think the Earth looked like millions of years ago. What name was given to this land mass.

• Plate Tectonics

• Oceana

• Pangea

• North America

Tectonic plates float on top of the ________

• Crust

• Mantle

• Inner Core

• Outer Core

the place where two different plates have contact.

• Pacific Plate

• Mountains

• Earthquakes

• Plate Boundaries

the process in which a denser plate is pushed downward beneath a less dense plate when plates converge; occurs at continental to oceanic boundaries and oceanic to oceanic boundaries

• divergent boundaries

• volcanic eruptions

• subduction

• convergent boundary

Occurs when two tectonic plates move away from each other.

• Divergent Boundary

• Convergent Boundary

• Volcanic eruptions

• Mountain building

Occurs when two tectonic plates slide past each other

• Transform Boundary

• Ocean Basin

• Spreading ridges

Name this boundary
