Question 1: Temperatures decline with increasing altitude in which atmospheric layers?

Stratosphere and thermosphere

Tropopause and stratopause

Mesosphere and thermosphere

Troposphere and stratosphere

E-Troposphere and mesospher

Question 2: Choose the correct answer

A-Latent heat is heat that you can measure with a thermometer.

Sensible heat is heat that is stored, and potentially could be released as latent heat.

B-Latent heat is heat that is stored, and potentially could be released as sensible heat.

Sensible heat is heat that you can measure with a thermometer.

Question 3: Over the course of a year, the equator's heating from the sun is:

(Hint: consider the pattern of the subsolar point movement in relation to the equator over the course of a year).

A-Uniform, due to the uniform solar insolation angle year round.

B-Has one distinct peak, as in the midlatitudes.

C-Has two distinct peaks associated with the subsoloar point crossing the equator twice.

D-Has four distinct peaks, associated with the two equinoxes and two solstices.

E-Has 64 distinct peaks, associated with the phases of the moon.

Question 4: If you were at the north pole on the northern hemisphere summer solstice, what would be the pattern of the sun's movement in a 24 hour period?

A-The sun would be below the horizon for the entire 24 hours.

B-The sun would be above the horizon for exactly 12 hours, though it would never be very high in the sky.

C-The sun would be directly overhead for the entire 24 hours.

D-The sun would move in a large circle around the sky, and there would be 24 hours of daylight.

E-The sun would be above the horizon for exactly 12 hours, and would be directly overhead at noon.

Explanation / Answer

1. E-Troposphere and mesosphere

Explanation: The troposphere is the layer where most of the world's weather takes place. Since temperature decreases with altitude in the troposphere, warm air near the surface of the Earth can readily rise, being less dense than the colder air above it. In fact air molecules can travel to the top of the troposphere and back down again in a just a few days. Such vertical movement or convection of air generates clouds and ultimately rain from the moisture within the air, and gives rise to much of the weather which we experience.

Temperatures in the mesosphere drop with increasing altitude to about -100C. The mesosphere is the coldest of the atmospheric layers. In fact it is colder then Antarctica's lowest recorded temperature. It is cold enough to freeze water vapor into ice clouds. You can see these clouds if sunlight hits them after sunset. They are called Noctilucent Clouds (NLC).

2. B-Latent heat is heat that is stored, and potentially could be released as sensible heat.

Sensible heat is heat that you can measure with a thermometer.

Explanation: SENSIBLE HEAT is the heat absorbed or given off by a substance that is NOT in the process of changing its physical state. Sensible heat can be sensed, or measured, with a thermometer, and the addition or removal of sensible heat will always cause a change in the temperature of the substance.

LATENT HEAT is the heat absorbed or given off by a substance while it is changing its physical state. The heat absorbed or given off does NOT cause a temperature change in the substance- the heat is latent or hidden.

3. C-Has two distinct peaks associated with the subsolar point crossing the equator twice.

Explanation: The summer solstice occurs at the moment the earth's tilt toward from the sun is at a maximum. Therefore, on the day of the summer solstice, the sun appears at its highest elevation with a noontime position that changes very little for several days before and after the summer solstice. The summer solstice occurs when the sun is directly over the Tropic of Cancer, which is located at 23.5° latitude North the sun is at its highest point in the sky and this is the longest day of the year.

The winter solstice marks the shortest day and longest night of the year. In the Northern Hemisphere, it occurs when the sun is directly over the Tropic of Capricorn, which is located at 23.5° south of the equator and runs through Australia, Chile, southern Brazil, and northern South Africa.

4. D-The sun would move in a large circle around the sky, and there would be 24 hours of daylight.

Explanation: The June solstice marks the longest daylight period of the year and the start of astronomical summer in Earth’s northern hemisphere. At 5:04 UTC (1:04 a.m. EDT) on June 21, the sun can be seen straight overhead along the Tropic of Cancer, while the North Pole reaches its maximum annual tilt toward the sun. As the planet rotates on its axis, areas within the Arctic Circle see the sun circle through the sky for 24 hours.
