8.9A, 8.9B, 8.9C Earth Science Review

Earth's layer composed of crust and upper-most solid mantle.

Which discovery supported the Theory of Continental Drift?

Occurs at a convergent boundary where continental plates cause large amounts of land to lift as the plates collide.

A phenomenon by which magma from Earth’s mantle comes up at the mid-ocean ridge and creates new oceanic crust.

On a topographic map, the steepest slope of a moutain is the area where the contour lines -

A tectonic plate boundary when a dense oceanic plate moves below a continental plate or another oceanic plate.

Deep and narrow depressions in the seafloor where the subducted plate moves into the asthenosphere.

Plotting which of the following events on a map could provide information on the location of tectonic plate boundaries?

Which of the following features is likely to form where two continental plates push toward each other?

The difference in elevation between two adjacent contour lines on a map.

In which layer of the Earth are tectonic plates found?

Which plate is the subducting plate at the Aleutian Trench? (circled in yellow)

Photos or images taken of Earth from space.

Parts of Earth’s surface that show evidence of the natural processes of weathering, erosion, and deposition of sediment

The Mid-Atlantic Ridge supports Plate Tectonic Theory because as you move away from the ridge the rocks-

The Dead Sea Fault off the coast of North Africa is an example of which kind of plate boundary?

A fence at the San Andres Fault shows an offset of 3' from one side of the fault to the other. Why?

Deep and narrow depression in the seafloor where the subducted plate moves into the asthenosphere.

Name the boundary type between two plates that slide past one another; known for sudden shifts resulting in earthquakes.

Hotter and more fluid layer of the mantle where convection currents occur.

Which type of tectonic plate movement results in the formation of mid-ocean ridges?

Evidence that supports the Theory of Plate Tectonics is the discovery of what in both South America and Africa?

Two surface features that can occur at continental to oceanic convergent boundaries.

The process by which gravity, water, wind, and ice transport sediment from one place to another.

A circular movement of fluids caused by the rising of hotter, less dense fluid and the falling of cooler, denser fluid.

A map showing changes in elevation of Earth's surface.

The theory that continents were once connected but have drifted apart.

In which direction is the river flowing?

A line on a map that connects points with the same elevation.

Patterns of rock found on opposite sides of the Mid-Atlantic Ridge are the same age and polarity. This is evidence of-

Which boundary creates rift valleys on land and mountainous ridges on the sea floor, both from plates

The four "agents of erosion" are: wind, water ice, and _________.

The disctance above sea level.

The highest peak represented by the topographic map can be found in which quadrant?

The process by which gravity, water, wind, and ice deposit weathered and relocated sediment.

Theory that the lithosphere is divided into tectonic plates that slowly move on top of the asthenosphere.

Subduction is when a less dense oceanic plate is pushed downward beneath a denser plate when plates converge.

The most recently formed crust on Earth would be found where –

The boundary between two tectonic plates moving toward each other when a denser plate moves below a less dense plate.

4In 1596, Abraham Ortelius theorized that the continents were once joined together. What led him to this idea?

The four agents of erosion are: wind, water, ice, and fire.
