Density is the measure of ________ of a material
Compactness
Convection is the movement that transfers heat in __________
Fluids (anything that flows; liquids, gases, liquid rock)
Which layer of the Earth is the LEAST dense?
Crust
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
Warm fluids are (more/less) dense than cold fluids, so they (float/sink)
Warm fluids are LESS dense than cold fluids, so they FLOAT.
In a house with 2 floors, which floor will typically be the warmest?
The 2nd or top floor
The crust
Define "renewable resource"
A renewable resource is consistently available or can be replaced in a short amount of time.
Which is the MOST dense? Solid, liquid or gas?
Solid
Which layer of the Earth has convection currents that drive plate motion?
The mantle
Which layer is made of liquid rock, better known as magma?
The mantle
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.
What are the correct units for density?
g/cm3
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.
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.
What are the THREE reasons why natural resources are unevenly distributed on our planet?
1. Geological processes
2. Earth's history
3. Climate
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.
How do changes in density create convection currents?
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
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
