CRUST
Pieces of crust that are separated by cracks all over the Earth
What are TECTONIC PLATES?
As you move towards the center of the Earth the temperature ____________.
What is "increases" or "gets higher?"
The layer of the Earth that we live on.
What is crust?
The type of rock created by the cooling of magma or lava.
What is igneous rock?
The supercontinent that was all the continents connected together 200-300 million years ago.
What is Pangea?
What is continental and oceanic crust?
This molten rock is located under the ground in the mantle and underneath the base of volcanoes or ocean ridges.
What is magma?
The layer of the Earth that is the only liquid layer.
What is the outer core?
The type of rock that is created by pieces of sediment being pushed together by compaction.
What is sedimentary?
This scientist came up with the idea of continental drift when he observed that the continents fit together like puzzle pieces. Sadly he dies before the theory was completely proven.
Who is Alfred Wegener?
You would find this type of rock on the crust after many years of layers of sediment and fossils are pushed together by the pressure of the ground.
What is sedimentary rock?
This molten rock is located above ground and flows out of volcanoes.
The layer of the Earth that is soft and bendable because of the heat of the Earth's core.
What is the mantle?
The type of rock that is created by both heat and pressure in the lower crust and mantle.
What is metamorphic rock?
When pieces of crust push together towards each other, they can create landforms such as these.
What are mountains?
The shaking of tectonic plates (pieces of crust) back and forth can cause these motions in the ground.
What are earthquakes?
Magma comes up into the surface of the crust at the base of the ocean at these underwater mountain chains which create a huge crack in the crust.
What is a mid-ocean ridge?
The layer of the Earth that has the most pressure.
What is the inner core?
When pieces of rock are broken off by wind or water and moved to different locations, these rock pieces are called _____________.
What are sediments?
When pieces of crust pull apart and cause dips or cracks in the land, they can create landforms such as these.
What are valleys or mid ocean ridges or volcanoes?
When crust sinks back down into the mantle because it gets too heavy, this process occurs.
What is subduction?
The PROCESS which moves the continents on tectonic plates because of heat movement underneath in the mantle.
What is sea-floor spreading?
The TWO layers of the Earth that are made up of iron and nickel.
What are the inner core and outer core?
Two processes that can cause rock to change are ___________ and __________.
What is: melting, cooling, weathering, erosion, pressure?
Name two pieces of evidence for Wegener's theory of continental drift.
Fossil evidence
Puzzle Pieces
Mountain ranges
Glacier/climate matchup
