Movements of Earth

What are plates?

• in the core of earth
• Blocks of crust and upper mantle rock that fit together like puzzle pieces
• parts of the earth's crust
• top layer

What is an earthquake?

• when crust shakes
• when the earth is still
• a movement of the ground caused by a sudden release of energy in Earth's crust

What is a focus?

• the place within the crust where energy is released during an earthquake
• the epicenter
• when the top layer erodes
• to stay focused

What is an epicenter?

• point on Earth’s surface directly above the focus
• center

What is a fault?

• a break in Earth’s crust
• a break in the mantle
• a break in the epicenter

What is a Richter scale?

• how earthquake are measured
• to measure the weight of the earth
• a scale to see the size of the crust

What are the 3 types of plate movements?

• fault, epicenter
• fast, slow, medium
• divergent, convergent, and transform
• plates, mantle and crust

What does the movement of a divergent plate look like and what is the strength of the quake?

• plates sliding past each other, weak
• plates pushing together, weak
• plates pulling apart, strong

What plate movement  slides past each other?

• divergent
• convergent
• transform

What is the plate movement where plates are pulling apart? What is the strength of a quake?

• transform, strong
• Transformers
• shield
