Earth's Crust
Any of Earth's large areas of land such as Africa, Asia, and North America.
What is a continent?
One very large section of hard, solid rock that make up Earth's outer layer.
What is a plate?
The place where two plates meet.
What is the plate boundary?
To examine in detail for a purpose.
What is "analyze?"
A sudden shaking of the Earth's surface.
What is an earthquake?
The layer of soft, solid rock underneath Earth's plates.
What is the mantle?
Plates that are moving toward the same place.
What are convergent plates?
Something we observe to be similar over and over again.
What is a pattern?
Where will you find hard, solid rock when you drill into the Earth?
What is everywhere?
What happens to the plates and mantle at a convergent plate boundary?
What is one of the plates bends and sinks underneath the other and becomes a part of the mantle.
Plates that move apart in different directions.
What are divergent plates?
A diagram that shows what the inside of something looks like.
What is a cross section?
Fossil remains of an extinct plant with large leaves have been discovered in India and Australia. All the plants were located together, but now are separated by an ocean. What could explain how these fossils got so far apart?
What is: India and Australia are parts of different plates. The plates slowly moved far apart as soft, solid rock from underneath got added to the edges of the plates over millions of years.
_________________ provide evidence that the plates of Earth's outer layer move.
What are earthquakes?
Any of the many processes (such as eruptions and lava flows) in which gas, lava, and ash are pushed out on the surface of Earth.
What is volcanic activity?
An underwater mountain range formed when two plates move apart.
What is a mid-ocean ridge?
A set of interacting parts forming a complex whole.
What is a system?
Earth's outermost layer of hard, solid rock that is underneath the soil, vegetation, and water.
What is Earth's Outer Layer?
What happens to the plates and mantle at a divergent plate boundary?
What is the plates move away from one another and the soft solid rock from the mantle comes up to form a mid-ocean ridge and add rock on to the end of the plates.
A long, deep indentation in the ocean floor formed when two plates move together.
What is a trench?
Evidence of life from the past, such as bones, footprints, or leaf prints.
What is a fossil?
