Plate Tectonics

The movement of the tectonic plates is caused by

• the rotation of the Earth.

• convection currents in the Asthenosphere

• the gravity of the iron-nickel core.

• the Moho discontinuity.

Subduction zones occur on Earth where dense oceanic crust dives under more buoyant continental crust. These boundaries are characterized by a deep ocean trench next to a high continental mountain range, large numbers of earthquakes and volcanoes. All of this is further evidence for the

• big bang theory.
• theory of plate tectonics.
• origin of the species.
• theory of natural selection.
  

There are three types of plate boundaries. Which choice is NOT a type of plate boundary?

• convergent
• thrust
• divergent
• transform

What geological forces might be responsible for this range of mountains?

• diverging tectonic plates
• erosion of the land by the ocean
• converging tectonic plates
• deposition of sediments by the ocean
  

The Earth’s surface is not a solid surface but is divided into

• several oceanic plates.
• continental and crustal plates.
  
• seven continental plates.
• continental and oceanic plates.
  

Pangaea is a theory where all continents began as

• one big country

• one big continent

South America and Africa look to fit together like a puzzle

• does not support the theory of Pangaea

• does support the theory of Pangaea

Fossils can also give evidence for a Pangaea theory

• True

• False

When a fossil of an animal is found on almost all continents, then it supports

• the idea of a traveling animal

• the idea of a connected original continent

• the idea of a flying animal

• divergent boundary

• convergent boundary

• transform boundary
