100

The type of weathering that occurs when a plant grows through a rock breaking the rock into smaller pieces (physical or chemical) 

What is physical weathering? 

100

The point on the surface of the Earth where the earthquake is felt

What is the epicenter? 

100

Magma that has reached the Earth's surface

What is lava? 

100

The type of stress that occurs at convergent boundaries

200

Made of a mixture of weathered rock particles and organic material from plants and animals

What is humus? 

200

The type of weathering that occurs when acid rain dissolves limestone (physical or chemical) 

What is chemical weathering? 

200

The point within the Earth where the earthquake originates from 

What is the focus? 
200

Thick mudflow that occurs when volcanic ash mixes with water 

What is Lahar? 

200

The type of fault that occurs along divergent boundaries due to tension stress; the hanging wall moves down relative to the footwall

300

The individual layers of soil found in a soil profile 

What are soil horizons? 

300
The type of weathering that occurs when ice expands in the cracks of a rock breaking the rock into smaller pieces (physical or chemical) 

What is physical weathering? 

300

The instrument used to detect and located earthquakes

What is a seismograph? 

300

Volcanoes that form in the middle of a tectonic plate

What are hot spots? 
300

The type of fault where rocks slide past each other horizontally; associated with earthquakes

What is a strike/slip fault? 

400

The smallest soil particle size that has high water retention and low permeability 

What is clay?

400

The process of carrying away weathered soil, rock, and other materials on the Earth's surface by wind, water, and gravity

What is erosion? 

400

The three types of seismic waves in the order they arrive on a seismograph

What are P-waves, S-waves, and Surface waves

400
The term that refers to how fast or slow a liquid moves 

What is viscosity? 

400

The three ways rocks respond to stress (The 3 Fs)

What are fold, fracture, and fault? 

500
The layer of solid, un-weathered rock that lies beneath the regolith 

What is bedrock? 

500

Mounds of sand that are deposited by wind and gravity erosion

What are sand dunes? 

500

A large wave triggered by an earthquake occurring where a slab of the ocean floor is displaced vertically along a fault

What is a tsunami? 
500

The most volcanically active zone on Earth located around the Pacific Plate 

What is the Ring of Fire? 

500

The two types of folds that occur when rock is exposed to extreme stress; the rock bends, but does not break

What are anticline and syncline?
