100
At this boundary, plates move away from each other.
What is a divergent boundary?
100
This layer is the outermost, thinnest, and solid rocky shell of Earth.
What is the crust?
100
Name this plate boundary.
What is transform?
100
This Earth layer has a density of 3.0 g/cm3.
What is the oceanic crust?
100
Earth is known to have many traits, but one that's important is that its curst is broken into....
What are plates?
200
These are large pieces of Earth’s crust (lithosphere) that move slowly over the asthenosphere.
What are tectonic plates?
200
This is the thickest and middle layer of Earth.
What is the mantle?
200
Name is process (not plate boundary).
What is seafloor spreading?
200
If I am 1,200 km beneath the Earth's surface (which is impossible), I must be in this layer.
What is the mantle?
200
Sinking happens not because of immensity, if a plate subducts its because of its.....
What is density?
300
This type of plate is more likely to subduct due to higher density.
What is an oceanic plate?
300
Composed mainly of granite, this type of crust is thicker but less dense than its counterpart.
What is the continental crust?
300
WHAT ARE THOSE???
What are hotspots?
300
To travel from the surface of the Earth to its center, I must travel this distance.
What is 6,378 km?
300
This process is known for pushing in an upward direction, our plates are moving due to…..
What is convection?
400
This feature forms at divergent boundaries on the ocean floor.
What is a mid-ocean ridge?
400
This layer is made mostly of iron and nickel and is fluid-like.
What is the outer core?
400
Name is process (not plate boundary).
What is subduction?
400
The Chile Ridge, a divergent plate boundary, is formed by these 2 plates.
What are the Nazca Plate and the Antarctic Plate?
400
The liquid in here is not like the shore, but our fluid layer is Earth’s…
What is outer core?
500
Changes to these two properties lead to cycling currents in the asthenosphere.
What are temperature and density?
500
As you move from the crust to the core, how does density change?
What is density increases?
500
Name this process.
What are convection currents?
500
The Mariana Trench is formed by these 2 plates.
What are the Pacific and Philippine Plates?
500
Earth’s liquid layer is hidden an concealed, but the motions there give Earth it’s….
What is magnetic field?
