Geography Exam 3 Study Guide Questions and
Verified Answers
What are mid -ocean ridges and what occurs there? Correct Answer: The mid-ocean ridges are where
new crust forms
How do igneous rocks form? Correct Answer: Any rock that is cooled and solidified from a molten state
How do sedimentary rocks form? Correct Answer: Form from eroded materials deposited in two layers
and cemented together
How do metamorphic rocks form? Correct Answer: It forms from another rock due to heat and pressure
Be able to categorize all the rocks discussed in class. Correct Answer: Granite is intrusive igneous, slate is
metamorphic, sandstone is sedimentary
Define the term mass movement and know some examples: Correct Answer: Mass movement is the
downslope of weathered materials in response to gravity: creep, mudslide, rockslide, slump, landslide
Know the characteristics of normal, reverse, thrust, and strike-slip faults Correct Answer: Normal faults
its tension in the crusts that means pull apart and mainly vertical motion. Reverse faults are compression
and also vertical motion. A thrust fault is a low angle reverse. Strike-slip is primarily horizontal
movement.
Know some examples of plutonic features. Correct Answer: Morro Rock in Morro Bay, locales and
bacolest
What volcanoes make up the core of the Hawaiian Islands? Correct Answer: Shield volcanos
How did Crater Lake form and what is caldera? Correct Answer: 4860 BC Mountain Zamo-whatever it
was a plug dome composite cone volcano, now it's Crater Lake and that's a caldera which is a crater
greater than 1 mile in diameter.
Know the order of events of how the earth and life formed according to the scientific community.
Correct Answer: Earth cools and solidifies, then we get atmosphere, then we get the oceans, life begins in
the oceans, life crawls out of the ocean, then we get early men
What are horsts and grabens? Correct Answer: Horst is a block of crust between parallel faults that's gone
up compared to the land on either side. The grabens are a block of crust that's dropped down between
parallel faults
