Plate Tectonics Quiz Review

Plate Tectonics Review

Lessons 1 - 3

Density

Formula for density is  $\frac{mass}{volume}$  .

** Found on Page 1 **

Density Triangle

Density = Mass / Volume

Mass = Density x Volume

Volume = Mass / Density

Multiple Choice

Practice:

(Density)

Frank has a paperclip. It has a mass of 9 g and a volume of 3  $cm^3$  . What is the density of the paperclip?

•  $\frac{1}{3}$ cm^3/g

• 3 g/cm^3

• 27 g/cm^3

Multiple Choice

Practice:

(Volume)

If Mary's textbook has a mass of 60 grams and a density of 5 g/cm^3, what is the volume of the textbook?

• 300 cm^3

• $\frac{1}{12}$ cm^3

• 12 cm^3

Why would a metal nail sink to the bottom of a glass filled with syrup but a grape would float on top?

Layers of the Earth

Properties & Characteristics

Inferred Properties of Earth's Interior

ESRT - page 10

Relationship of Temperature, Pressure, and Density To Depth

• The closer the layer is to the inner core, the higher the temperature. * The inner core is theorized to be as hot as the surface of the Sun! *

• Layers increasing in depth also increase in pressure.

• Densities of each layer increase as the depth increases.

Multiple Choice

Using the graph on page 10, which layer has a pressure equal to 2 million atmospheres?

• Outer Core

• Inner Core

• Mantle

• Lithosphere

Multiple Choice

Using the graph on page 10, which layer has a temperature of 3,500 $\degree$ C ?

• Outer Core

• Plastic Mantle

• Stiffer Mantle

• Lithosphere

Multiple Choice

At which depth does the density of that layer equal 12.9 g/cm^3?

• 4,650 km

• 5,000 km

• 5,250 km

• 6,200 km

Poll

The outermost layer of Earth is the ________.

• Crust

• Mantle

• Core

• Asthenosphere

Poll

Which layer is made of liquid?

• Mantle

• Outer core

• Inner core

• Lithosphere

Multiple Select

Check which two (2) layers are considered the lithosphere.

• Crust

• Asthenosphere

• Rigid Mantle

• Outer core

• Inner Core

Plate Tectonics

Slabs of the lithosphere that float on the mantle.

These "pieces" are constantly moving (about 1-5 cm/year) and create new landforms.

There are 10 major plates and several minor plates.

Evidence of Plate Tectonics

• Pangea - Shorelines fit like a puzzle

• Identical fossils in different continents

• Rock layers of same ages/compositions in different continents

• Seafloor spreading

• Alternating magnetic polarity

Two Types of Crust

Oceanic - Thinner, basaltic, MORE dense (3.0 g/cm^3)

Continental - Thicker, granitic, LESS dense (2.7 g/cm^3)

Movement of Tectonic Plates

Convection cells are theorized to be the cause of tectonic plates moving.

Multiple Choice

The ______ plate boundary is where two plates come together.

• convergent

• divergent

• transform

Multiple Choice

The transform plate boundary is where two plates ________.

• spread apart.

• come together.

• slide past each other.
