B  Lava flows

C  Ice from an old glacier

D  Fine material that comes down in a flash flood

A  That tribes used to build giant head statues in the area

B  That ice causes large rocks to slide

C  The force of the water that comes down the canyons during a flash flood from sudden rain.

D  That glaciers used to be in the valley

E  That volcanoes hurled large rocks many miles from their craters

A  The mountains channel moisture into Death Valley, causing the great floods

B  The mountains block birds and pollen from getting into Death Valley, known as the Coriolis effect

C  The mountains block birds and pollen from getting into Death Valley, known as the anti-animal shearing effect

D  The mountains block moisture from getting into Death Valley, known as rain shadow effect

A  Lava boiled off Lake Manly giving rise to the salt we see today.

B  It occurs after snowfalls. The ice will melt leaving salt on the valley floor.

C  Rain water comes in and, the moment the water starts to evaporate, salt crystals start to form.

D  Tortoises secrete salt from their nasal glands and over millions of years it piles up to the salt we see.

A  Frequent earth tremors cause the salt to move and then settle resulting in a pop.

B  Lava flows at shallow depth cause the surface to pop.

C  No one knows.

D  The sun sucking out the last of the moisture from the surface. The salt crystals expand and contract from the heat which causes the popping.

E  About 10 square miles over 10 feet deep.

A  The direction of a meteorite impact.

B  The direction of wind flow.

C  The direction of animal tracks.

D  The direction of the lava flow.

E  The direction of water flow.

A  It shows there was once fresh water in Death Valley.

B  It shows there were once many dinosaurs in Death Valley.

D  It shows there was once an ocean in Death Valley.

A  Gold

B  Sulfur

C  Halite

D  Borax

E  Clay

A  Continental crust being pulled apart at a faster rate and magnitude anywhere on Earth

B  The ritual tea kettle pileup on the first Thursday in November

C  The birth of a new mountain chain

D  The formation of the ocean floor because it is 282 feet below sea level

A  Around the globe it averages 18 miles thick. The continental crust in Death Valley is 16 miles thick so it is a little thinner due to the stretching of the plain.

B  Around the globe it averages 16 miles thick. The continental crust in Death Valley is 16 miles thick so it is the same.

C  Around the globe it averages 25 miles thick. The continental crust in Death Valley is 16 miles thick so it is much thinner due to the stretching of the plain.

D  A round the globe it averages 20 miles thick. The continental crust in Death Valley is 20 miles thick so it is the same.

A  1 million years

B  7 million years

C  20 million years

D  13 million years

E  3 million years

A  Turtlebacks are deformed rocks that were formed at low temperature and pressure at the surface

C  Turtlebacks are shiny rocks that were formed at low temperature and pressure within the earth

D  Turtlebacks are deformed rocks that were formed at high temperature and pressure within the earth

A  Veins of uranium

B  The presence of basalt

C  The occurrence of subductionite

D  Veins of granite

A  They were frozen over by massive glaciers
