Earth's Layers
The lithospehere is made up of
the crust and upper mantle
When two boundaries come together they are called
convergent boundaries
The Super Continent is called
Pangea
A break in Earth's crust is called a
fault
The math property that says the order of numbers does not matter in an addition problem.
Example: 2 + 3 = 3 + 2
commutative property of addition
A hot, dense, asphalt-like layer of rock that flows causing the plates of the Earth to move is called the
mantle
When two plates come together and one plate goes under the other it is called
subduction
Earth's crust and the top part of its mantle are divided into sections. The sections are called
plates
The model that explains how Earth's moving plates create landforms is called
Plate tectonics
The property that states that the grouping of numbers in an addition problem does not matter.
Example: (2 + 3) + 4 = 2 + (3 + 4)
Associate Property of Addition
What causes convection currents in the Asthenosphere that slowly moves the Earth's crust?
Heat from the core
Earthquakes occur at what type of boundary
transform boundary
The movement of plates is called
continental drift
The slow upward heaving of Earth's surface is called
uplifting
What word means "land between two rivers"?
Mesopotamia
The hottest part of the Earth that is a solid ball made mostly of iron and nickel is called the
Inner Core
What is formed at divergent boundaries?
creation of sea floor and earthquake activity
The individual who first came up with the theory of continental drift was
Alfred Wegener
The bending upward of Earth's crust to form mountains is called
folding
Mesopotamia lies between which two rivers?
Euphrates River
Tigris River
Scientists believe that the movement of the Iron in the outer core creates
Earth's magnetic field
The entire surface of Earth, from the tops of mountains to the ocean floor, is made up of the
crust
What evidence is there to suggest that continental drift occurred?
pieces of land look like they would fit together like pieces of a puzzle
fossil records show similar plant life and animal life on different continents, suggesting they were together at one time
The process by which liquid rock flows up and outward through a narrow valley to form ridges of new crust on the ocean floor is
seafloor spreading
What present day country is located where Mesopotamia once was?
Iraq
