200

Which layer of the geopshere is made of liquid iron a.) asthenosphere b.) mantle c.) inner core d.) outer core

300

Convection currents help drive the process of plate tectonics. Which part of the geopshere do these currents occur at. a.) Outer core b.) Crust c.) Lithosphere d.) Asthenosphere

d.) Asthenosphere

400

The process of the rock cycle take place in which location? a.) deep inside the geopshere b.) in the atmosphere c.) on Earth's surface d.) both a and c

d.) Both A and C on the earth surface (lava cooling and deep inside)

500

What are the two types of crust that make up the earth's surface? Which type is thinner/thicker? Which is more dense/less dense

Continental and Oceanic Crust. Oceanic crust is thinner but more dense while Continental is thicker but less dense.

Earth Systems

100

True of false: The outermost earth system is made of water?

False, the outermost system is the atmosphere

200

Which of the following is NOT one of the four systems into which scientists divide Earth? A.) Geosphere B) Hemisphere C) Hydrosphere D.) Biosphere

B) Hemisphere

300

If you are attempting to determine the main type of rock found in an area, which of Earth's systems are you studying?

Geosphere

400

Name all four of Earth's Systems and what their roles are.

Atmosphere-Air/Weather/Protection Geosphere- Solid Part of the Earth Biosphere- All living things Hydrosphere- Water

500

Which of the following is part of the geosphere? a.) a cloud b.) a plant c.) a deer d.) a cliff

a cliff

Plate Tectonics

100

True of False; Mid-ocean ridges are formed along lines where two plates diverge under the water

TRUE

200

Match each term with the correct statement below. a. mid-ocean ridge b. convergent boundary c. subduction zone 1. Plates move together at a(n) _____. 2. One plate is forced under another in a(n) _____. 3. A(n) _____ is like an underwater mountain chain.

1. B 2. C 3. A

300

What is the term for the large, rigid pieces of earths crust? a.) faults b.) sediment c.) mountain d.) tectonic plates

d.) tectonic plates

400

What is the theory of plate tectonics? and why is it important?

Earth's surface is broken into large, rigid, pieces that move with respect to each other. This process is powered by convection currents in the earths mantle. The theory is important because it explained much about how Earth changes over time.

500

What are 2-3 pieces of evidence that were discussed that helped support the theory of plate tectonics?

 Fossil Evidence/ Apparent fit of Continents 

Earthquakes and Volcanoes 1

100

What location does most volcanic and seismic (earthquake) activity occur in the world?

Ring of Fire

200

At what type of plate boundary do volcanoes form? a.) Convergent b.) Divergent c.) Transform d.) Nau

Convergent Boundary

300

True or false, The magnitude of an earthquake can range from less than one to at least 20? What is the tool used to measure the power of an earthquake?

1-10, ritcher scale

400

What is a fault? 

A fault is a crack in the crust where movement occurs. 

500

What are the three main types of volcanoes?

Cinder Cone, Shield, and Composite (strato-volcanoes)

Earthquakes and Volcanoes 2

100

Which statement is true? a.) melted rock under the surface is called lava b.) melted rock under the surface is called magma c.) melted rock on earth surface is called magma d.) Magma is the correct scientific term for melted rock regardless of where it is located

b.) Magma under the surface is called magma

200

In order, what are the seismic waves that effect an area that has been hit by an earthquake? a.) Primary waves, Surface waves, Secondary waves b.) Secondary waves, Surface waves, Primary waves c.) Surface waves, Primary waves, Secondary waves d.) Primary waves, Secondary Waves, Surface waves

d.) Primary waves, Secondary Waves, Surface waves.

300

What is the area called where one plate (oceanic) is forced below another plate (continental? What type of boundary occurs here?

Subduction zone; convergent boundary

400

What type of boundary is known to cause earthquakes?  

Transform 

500

How are volcanoes formed? 

Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface. At the surface, it erupts to form lava flows and ash deposits. Over time as the volcano continues to erupt, it will get bigger and bigger.
