8.3 The Sun Powers Earth`s Climate System Homework - Thursday 09/06/12 pg. 329 #1-6

1. Explain how the ocean interacts with the Sun’s radiation.
The ocean interacts with the Sun’s radiation by reflecting and absorbing the Sun’s radiation. I think the ocean absorbs the radiation because depending on the season the area by the mass of water is about 1°C or 2°C difference in temperature proving the ocean does absorb the Sun’s radiation. Although it absorbs heat I also thing the ocean has a medium albedo. The ocean is light coloured/clear, and is a different form of ice which has the highest albedo. Therefore the ocean interacts with the Sun’s radiation by reflecting and absorbing the heat energy.

2. The amount of energy
4. A) Describe what happens to the Sun’s energy once it reaches Earth.
Once the Sun’s energy reaches Earth it is either absorbed by something or reflected. Objects which absorb the energy convert it into heat. Some objects like green plants take some of the energy and convert it into a stored form of energy such as sugars. This absorbed energy is what ultimately drives the climate. If the energy is not absorbed it’s then reflected back into the atmosphere. This is what happens to the Sun’s energy once it reaches Earth.

B) Describe what happens to the energy Earth emits.
The energy absorbed by the Earth’s surface affects the temperature by increasing; this is known as thermal energy, the energy present in the motion of particles at a particular temperature. After the energy is absorbed the Earth then emits mostly lower-energy infrared radiation back out.

5. A) What would you expect to happen to the temperature on Earth if the amount of energy radiated by Earth increased but the amount coming from the Sun stayed the same?
I would expect that the Earth’s temperature would drop to a cold environment. I think this because if Earth began to radiate more energy than the average amount of energy on Earth would drop, because the Sun’s radiation would stay the same. The amount of energy we constantly have is proper for a sustainable environment for all living things; if Earth began to release more energy than what
