Earthly Awesome
Underneath the soil and ocean, Earth's outer layer is made of this.
What is hard, solid rock?
Two plates that move apart, rose and hardened, adding solid rock to the edges of both plates.
What is a divergent plate boundary?
Something we observe to be similar over and over again.
What is a pattern?
Plates that move together will allow one plate to go underneath and sink into the soft rock below. It is a type of plate boundary.
What is convergent plate boundary?
Earth's outer layer is made of sand and water.
What is false?
The Lystrosaurus lived together on land, and they could not swim, and now there is an ocean between the fossils. This is what the plates did.
What are move apart?
What are patterns?
A diagram showing what the inside of something looks like.
What is cross section?
The layer of soft, solid rock underneath Earth's plates.
When two plates move away from each other one will find soft, solid rock from underneath plates and then rise and harden, adding solid rock to the edges of both plates.
What is true?
Any of Earth's main areas of land, such as Africa, Asia, and North America.
What is continent?
The place where two plates meet.
What is plate boundary?
Evidence from the past, such as bones, footprints, or leaf prints.
What is fossil?
Geologists drill to study hard, solid rock. This is where they can drill on Earth to find it.
What is everywhere?
Rifting is the slow pulling apart of land that is caused by plate movement.
What is true?
Convergent plate boundary.
What are plates that are moving toward each other?
Divergent Plate Boundary.
What are plates moving away from each other?
A long, deep indentation in the ocean formed when two plates move together.
What is trench?
How often or fast something happens.
What is rate?
Rock of the same type and age formed during volcanic eruption is found on the Baja Pennisula and the coast of Mexico.
What is true?
What is be experienced (felt) by humans?
Three requirements of geologists to help them understand what is happening underneath Earth's surface.
What are investigate, gather evidence, and build models?
What is mid-ocean ridge?
Plates move very slowly, it could take this long for them to travel great distances.
What is millions of years?
The plates of Earth's outer layer do not move.
What is false?
