The solid outer layer of the Earth where the tectonic plates are located.
What is the crust?
100
When the plates collide or push together and cause mountains and earthquakes.
What is convergent?
100
The theory that the continents have moved in the past and are continuing to move is called.
What is continental drift?
100
The Himalayan Mountains are growing because the Indian plate and Eurasian plate have this type of plate boundary.
What is convergent?
100
This type of rock is made when other rocks melt into magma then cool and crystallize.
What is igneous
200
The solid center of the Earth that is made mostly of iron and nickel. It is very dense.
What is the inner core?
200
When two plates slide side by side and create fault lines and earthquakes.
What is a transform boundary?
200
The giant landmass that gave rise to our 7 continents was called.
What is Pangaea
200
The San Anrea's Fault in Western United States is caused by this type of plate boundary.
What is tranform?
200
This type of rock is formed when other rocks are put under extreme heat and pressure and they change.
What is metamorphic?
300
This is a liquid layer that is made of nickel and iron. It is the second layer from the inside.
What is the outer core?
300
When one plate moves underneath another plate which leads to volcanoes and earthquakes.
What is subduction?
300
One of Wegener's pieces of evidence was that the edges of the continents....
What is "fit like a puzzle"?
300
The MidAtlantic Ridge gets wider every year because of this type of plate boundary.
What is divergent?
300
This type of rock is made from the erosion and weather of other rocks. The small pieces get cemented back together. Fossils are found in this rock.
What is sedimentary?
400
This is a thick semi solid layer that contains convection currents.
What is the mantle?
400
When hot magma in the mantle rises and then cools and sinks, it creates movement in the mantle called.
What is convection currents.
400
Today's evidence for Continental Drift is the discovery of sea-floor spreading and the use of this technology.
What are satellites and GPS?
400
Mount St. Helen's and many of the volcanoes around the Pacific Ring of Fire are formed from this type of convergent boundary.
What is Subduction?
400
The process that new rocks are formed from old rock material is called.
What is the rock cycle?
500
The rotation of the outer core around the inner core creates this.
What is the magnetic field?
500
When plate move away from each other and cause rifts, sea-floor spreading and volcanoes.
What is divergent?
500
Besides the fossils, rocks and mountains ranges on different continents matching up, the 4th piece of evidence that Wegener used was.
What is climates?
500
Mars does not have active volcanoes and other geological events like we have on Earth. Scientists believe this is because Mars does not have ______________________ anymore.
What are convection currents?
500
All rocks can be tranformed into another type of rock under the right conditions...true or false...
