Density is the measure of ________ of a material

Compactness

100

Convection is the movement that transfers heat in __________

Fluids (anything that flows; liquids, gases, liquid rock)

100

Which layer of the Earth is the LEAST dense?

Crust

100

Give an example of a natural resource AND give an example of a synthetic product

Natural resource: any materials from the Earth that are used to support life and the development of civilization

Synthetic product: any man-made materials that are made with natural resources

200

Warm fluids are (more/less) dense than cold fluids, so they (float/sink)

Warm fluids are LESS dense than cold fluids, so they FLOAT.

200

In a house with 2 floors, which floor will typically be the warmest?

The 2nd or top floor

200
Which layer of the Earth is made up of continental and oceanic plates?

The crust

200

Define "renewable resource"

A renewable resource is consistently available or can be replaced in a short amount of time.

300

Which is the MOST dense? Solid, liquid or gas?

Solid

300

Which layer of the Earth has convection currents that drive plate motion?

The mantle

300

Which layer is made of liquid rock, better known as magma?

The mantle

300

Define "non-renewable resource"

A non-renewable resource cannot be replaced easily and it would take millions of years for the Earth to form them again.

400

What are the correct units for density?

g/cm3

400

State an example of convection that happens in real life.

Ocean currents, air currents, lava lamps, liquid rock in the mantle, heating water in a pot, etc.

400
Even though the inner core is hot enough to melt and become a liquid, why is it solid instead?

The inner core has more pressure being exerted on it than any other layer. It bears the weight of the outer core, the mantle and the crust.

400

What are the THREE reasons why natural resources are unevenly distributed on our planet?

1. Geological processes

2. Earth's history

3. Climate

500

Why are gases and liquids considered to be fluids, but solids are not?

Solids have particles with no spaces between them to allow them to move. Therefore, solids cannot flow like liquids and gases can. 

500

How do changes in density create convection currents?

When a material heats up, it becomes less dense and rises. Once it cools down, it becomes more dense and sinks.
500

If continental crust and oceanic crust meet at a convergent plate boundary, which plate would be subducted and WHY?

The oceanic plate would be subducted because it is more dense than continental crust

500

What are 3 major effects on humans due to the uneven distribution of natural resources?

1. Locations of homes

2. Jobs people have

3.Trading with other countries

4. Going to war with other countries

5. Economic impact
