Describe the structural and compositional layers of Earth.

Which statement refers to convection?


Sunlight travels through space without the aid of fluids or solids.


Land and ocean absorb and re-emit heat from the sun.


Some of this energy is reflected off Earth's atmosphere.


Warm air rises and takes heat with it; eventually it cools and sinks.

Heat Transfer Lab

The following represents a lab set up for heat transfer. The cup on the left started with boiling water at 100 degrees C and the cup on the right has water at 20 degrees C. There is an aluminum bar between the two cups allowing heat to transfer from one cup into the other. The set up will be left alone for 20 minutes and temperatures of each cup of water will be recorded every minute for 20 minutes.

After you set up a fish tank, you are sure to see algae growing in it. There is plenty of light, fertilizer in the form of fish droppings, and plants or glass for algae to cling to. You may see green strings of algae in the water or green spots growing on the glass. Your whole aquarium can turn green if you don’t stop the algae. To prevent the problem, you can add algae-eating fish or microorganisms to the water. Covering the aquarium for a few days will also kill algae, which need photosynthesis to survive.

Multi-celled algae grow into larger organisms through cell division. For one-celled algae, the purpose of cell division is

Question 1: A measure of the amount of matter in an object


Question 2: the force or speed with which something moves


1.momentum
2.collision
3.exert
4.mass
5.velocity

How do you put this in your own words-

This amount depends on the latitude of the area. Latitude is the angular distance in degrees north and south from the equator. Different latitudes receive different amounts of solar energy.
