The professional name for a scientist who studies the interior of the Earth.

Geologist

100

What evidence do geologists use to study what is inside of the Earth?

Seismic Waves

What is heat tranfser? (HINT: Heat transfers from what to what?)

The transfer of heat from a warmer object to a cooler object.

How many years has Mr. Middleton been a teacher?

5 years

100

The deeper inside the Earth you go, the greater the...

Temperature AND Pressure.

200

Earth's Crust is composed mainly of these two rocks.

Continental = Granite

Oceanic = Basalt

A 7.4 magnitude earthquake occurred in California this week. Although we couldn't feel it, it helped us see what was under our feet. How were we able to pick up the seismic waves in New York?

Since California is wset of us, the seismic waves from the Earthquake could be recognized by a seismograph.


ALSO: The waves did not have to travel through the outer core.

200

The sun heats the Earth through what type of heat transfer?

Radiation (Heat transfer through open space.)

200

How long does it take the moon to revolve around the Earth?

27 days

200
The hard and rigid uppermost part of the mantle.

The lithosphere.

300

A man was driving and was almost involved in a car accident. In order to evade, he crashed into the side of a cliff. The cliff was shattered and caused rock to break down. Would this be considered a destructive force?

EXPLAIN

No. Although the rock was broken down and moved, it does not count as a destructive force as it was done by a human. Destructive forces can only be natural to Earth.

300

What are the layers of the Earth in order from outside --> to inside.

What is the largest layer?

What is the warmest layer?

Crust, mantle, outer core, inner core.

Mantle

Inner Core

300

When grilling food, you feel the heat from the stove as it is cooking the food. What two types of heat transfer are occurring?

Conduction: Cooking the food that is touching the pan (direct contact).

Radiation: Feeling the heat from the side of the stove. (open space).

300

He invented the brand Apple (iPhone, Macbook).

Steve Jobs

300

The soft layer below the lithosphere.

Asthenosphere

400

The island of Mauna Kea in Hawaii was once an active volcano. It is only 1 million years old (humans appeared 3 million years ago). How could a landform be so young if land has been around for billions of years?

The island of Mauna Kea was created because it was a volcano. The volcano is a constructive force and created an island as it erupted.
400
What is the only liquid layer of the Earth? Why is it a liquid?

Outer Core

It is extremely hot, but does not have immense levels of pressure. The temperature melts the rock/metals but the pressure does not compress them into a solid.

400

There is a pot of water sitting on a hot stove that is beginning to bubble. What heat transfer is causing the hot water to rise and bubble at the top of the pot? Why?

Convection. The hot water at the bottom of the pot rises because it is less dense. It cools off and becomes more dense.

400

This U.S. state is home to the Grand Canyon.

Arizona

400

This causes convection currents in the mantle (HINT: the heat source...)

The core (inner/outer).

500

The land we stand on sits on top of giant slabs of rock that are moved by the Asthenosphere. What are the giant slabs of rock called?

Tectonic Plates

500

What are the sizes of each layer? (MILES)

Crust: 5-30 miles

Mantle: 1800 miles

Outer Core: 1400 miles

Inner Core: 800 miles

500
The mantle is heated by the outer/inner core. This causes melted rock to become heated, rise, cool off, and fall back down. This cycle continues on and on. What do we call this cycle?

Convection Currents in the Mantle.

500

This is the number of lug nuts found on a wheel. (Car, truck, etc.)

Five

Geologists classify rocks into these three categories.

Igneous, metamorphic, and sedimentary.
