Answer:
C. Increased exposure to UV radiation.
D. Humans would be subject to more x-ray radiation from space because our atmosphere would not block it.
Explanation:
- <u>The electromagnetic radiation travels in a waveform and knows by the protons that form by the propagating electrical and magnetic fields and these protons undergo absorption as they transfer energy to atom within objects.
</u>
- These rays when emitted from the sun in the form of incoming short solar radiation reach the earth in one billionth of a second.
- Due to the absence of the ozone and other filters of the atmosphere the UV can dramatically impact the skin cells and would be more vulnerable to radiation exposure.

First, you need to find the coordinates of each point: M, T, J, and K.
M is (9, 8)
T is (-6, -1)
J is (7, 2)
K is (1, -8)
P is the midpoint between M and T.
Q is the midpoint between J and K.
The numbers in italics were derived by adding the absolute values of M + T and J + K and dividing by 2.
<em>7.5 and 4.5</em>
P is T plus the two numbers above.
P = (1.5, 3.5)
<em>3 and 5</em>
Q is K plus the two numbers above.
Q = (4, -3)
Then you just plot them on the graph and draw a line connecting P and Q.
M is the midpoint of line GR.
We know that M is at the origin, (0,0), and one of the points G is at (-8,3).
If M is the midpoint, then that means that R is the same distance away from M as G, although in the opposite direction.
Then we can deduce that R = (8,-3).
Explanation:
Effects of Wind
on forecasted temperatures
At night, the earth's surface cools by radiating heat off to space. The strongest cooling takes place right near the surface while temperatures at roughly 3000 feet are actually warmer than those at the surface. On a windy night, some of the warmer air aloft is mixed down towards the surface. This occurs because the winds are faster aloft than at the surface.
To visualize this, place one hand over the other about six inches apart. The bottom hand represents the air near the surface and the top hand represents the warmer wind higher up. Move the bottom hand slowly and the upper hand faster (to indicate the faster winds aloft). The faster air above and slower air below causes the air to overturn or spin (as in the picture below). This overturning motion is how warmer air from above is transported downward on windy nights.
