Earth's Layers
Name the three main layers of the Earth.
Crust, mantle, core
When two plates slip past each other horizontally, it is called...
Transform Boundary
Continents and Oceans
(Blank) is when pieces of the Earth are deposited, or dropped, somewhere else.
Deposition
Name two types of destructive forces.
Weathering and Erosion
The outermost solid shell of the Earth, a relatively thin layer of rock that varies in thickness and composition. It is the surface upon which we live and is broken into tectonic plates.
Crust
A (blank) boundary occurs when two pieces of the Earth move apart from one another.
Divergent Boundary
What is a mountain or hill that has magma under its surface? Some of these erupt and some don't.
Volcano
Deposition by water occurs in (blank), (blank), and (blank).
The tiny pieces that break off the rock are called?
Sediment
A layer of Earth situated between the crust and the core. Convection currents in the (blank) drive the movement of plate tectonics. In addition to the movement of plate tectonics, the (blank) controls volcanic activity as well as the formation of mountains.
Mantle
This is the name of the supercontinent that existed millions of years ago before the continents drifted apart.
Pangea
What is the landform created when the ground collapses and the bedrock gets washed away?
Sinkhole
Running water deposits (blank) where the slowing water can no longer move them.
Sediments
Erosion is when (blank) and (blank) change Earth's surface.
Wind and Water
The planets innermost layer, a dense sphere composed primarily of iron and nickel. It’s divided into a solid inner (blank) and a liquid outer (blank). The outer (blank) movement is responsible for generating Earth’s magnetic field.
Core
Who is the scientist that proved the theory of continental drift?
Alfred Wegener
(Blank) and (blank) are made from cliffs. One is a pillarlike mass that has broken off of the cliff. The other is a rock shaped like an arch that is still attached to the cliff.
Sea arches and sea stacks
Material can be deposited when (blank) changes direction or loses its strength.
Wind
A (blank) is a landform made of glacial till, which is unsorted and unstratified debris deposited by glaciers.
Moraine
Which layer of Earth do we live on?
Crust
This type of plate boundary happens when two tectonic plates crash into each other, often forming mountains like the Himalayas.
Convergent Boundary
This landform is formed when large amounts of sediment collect at the bottom of a mountain.
Alluvial Fan
Deposition by ice can occur when (blank) melt, leaving behind a feature known as a (blank), large chunks of broken rock and smaller sediment that settle at the base of the glacier when it melts or recedes.
Glaciers, Moraine
What canyon in the United States was carved by the Colorado River in the State of Arizona?
The Grand Canyon
