Rapid chemical weathering can be caused by a type of rain combined with pollutants. What is this type of rain called?

Humus makes soil rich in nutrients that plants need to grow. What is soil called when it is rich in nutrients?

Wind Weathering

River Weathering

Acid Rain

Lichens producing acid on rocks

Dark organic material in soil

Which environment causes weathering to happen faster?

pH is the measure of _____.

____________________ weathering occurs when abrasion and other natural agents physically wear away rock.

Rocks that are _____________ are full of connected air spaces and weather more easily.

Earthquakes most often occur

Which station was closest to the earthquake's epicenter?

This type of wave travels along Earth's crust and can be very destructive.

Second waves to arrive in an earthquake

What is the minimum number of seismograph stations needed to locate an earthquake epicenter?

Measures the magnitude or size, of an Earthquake

Transform boundaries have shearing stress and _______________________ faults.

In these faults, the block above the fault slides down relative to the other block.

Convergent boundaries have compression stress and ___________________ faults.

A force that acts on rock to change its shape or volume.

Which is an example of a transform plate boundary?

When does a divergent plate boundary form?

What is Pangaea?

What happens as the seafloor spreads apart?

Which can be used as an indicator of past climate?

What is the best definition for lithosphere?

Who came up with the theory of Pangaea?

When one layer of crust (usually oceanic) sinks back into the mantle because of differences in density, it is called:

At this type of boundary, plates move away from each other

At this type of boundary, plates slide past each other

At this type of boundary, plates collide with each other

This causes plate tectonics

This forms at a divergent boundary on land:

When two plates meet at a convergent boundary and subduction does NOT happen, it tends to form

What type of boundary is shown

The evidence is in ______________________, where coastlines and mountain ranges appear to fit together like a puzzle all over the world

Other evidence include __________________ that plate tectonics does occurr in the crust of the Earth.

The __________________ are chains of undersea mountains.

A theory explaining the structure of the earth's crust is called _________________
