This layer of earth contains large quantities of molten rock and is the primary source of the magma for hot spots
Mantle

A large slab of rock comprised from earth's lithosphere.
Techtonic Plate

Three types of folds are
Anticline, Syncline, Monocline

the ridge in the middle of the atlantic ocean where magma is released.
Mid Atlantic Ridge

An explanation of the formation of the solar system, in favor of a dust cloud being compressed and fused into the sun, with eventual planets forming
Protoplanet Hypothesis
200
This is the name of the superconteinet that existed 240 million years ago, and perused its eventual separation into the continents we know today
Pangea

These are a few types of evidence used to support the claim of the existence of tectonic plate movement
Fossil Evidence, Plant Evidence, Mountian evidence
200
A fold in the earth where rock is compressed into a downward parabolic shape
Syncline Fold
200
The oldest rock samples in the mid ocean ridge are towards the ______ due to seafloor spreading in the center creating new rock
Coastal areas

After earths initial formation these three sources of energy contributed to its heating
Gravity, Chemical reactions, friction
300
These are the three chemical layers of the earth
Crust, Mantle, Core
300
The three main types of plate boundaries and the corresponding forces are...
Divergent- Tension Covergent- Compression
Transform- Shearing
300
The three types of faults and their corresponding forces are
Normal- Tension Reverse- Compression
Strike slip- Shearing
300
A location of volcanic activity not near a plate boundry is a
hot spot

These are the structural layers of the earth
Crust, Lithosphere, Astenosphere, Mantle, Outer core, Inner core

Magnetic reversals are thought to be...
Random or Unpredictable
500
This force caused molecules to differentiate into layers
Gravity
500
P waves move in a tangent formation and can pass through solids and liquids while these waves move in a curvery pattern and can only pass through solids
S waves

The distance between Hawaii and kaholawe is 129 KM. The age of kaholawe is about 1 Million years old. Utilize the given information to calculate the speed per year at which the pacific plate moves over the hot spot. Put your answer in centimetres (Speed = distance / time)
The plate moved at a speed of 12.9 CM per year
