90% Answer Correctly

	O
	AO
	AB
	B

Convert 5C° to F°.

53% Answer Correctly

	-23
	37
	27
	41

Solution

To convert from C° to F° use:

\(F° = {9 \over 5}C° + 32\)

\(F° = {9 \over 5}(5) + 32\)

\(F° = {45 \over 5} + 32\)

\(F° = 9 + 32 = 41\)

The coldest point in the Earth's atmosphere is reached in which atmospheric layer?

52% Answer Correctly

	thermosphere
	mesosphere
	stratosphere
	troposphere

Solution

In the mesosphere, temperature again drops as altitude increases until the coldest point in the Earth's atmosphere, the mesopause, is reached where temperatures fall to −225 °F (−143 °C).
