Question

You will be climbing a mountain with very high elevation. What instrument should you bring along to determine the atmospheric pressure?
A. Anemometer B. Barometer C. Physchrometer D. Thermometer


Which of the following can happen to solar energy after it enters the earths atmosphere?

A. Absorbed by the earths surface.

B. Absorbed by celestial bodies

C. Reflected at the thermopause

D. Reflected by the moon


What is the relationship between air pressure and wind? ( please don't copy googles answers) open ended question



The boater is wondering if it will rain. She uses a sling phychrometer to measure the moisture content of the air relative to the temperature. She is measuring which characteristic of air?

A. air pressure

B. Precipitation

C. relative humidity

D. Temperature

Answer 1

1) b
2)c
3)None.Wind is large scale air movement to equalize horizontal pressure differences in the atmosphere. The reason for such pressure differences, as far as atmosphere is concerned, is always heat due to the radiation of the sun.//////////the pressure is more powerful than the wind itself.
4)c

Answer 2

Answer 1:

B. Barometer

Explanation:

A Barometer is used to measure the atmospheric pressure. Also, as  the height from the sea level increases the atmospheric pressure decreases. On going to a very high altitude like THE HIMALAYAS the atmospheric pressure is approx 1/3 of the pressure at sea level which will lead to the low level of oxygen in the blood and may cause nose bleeding.

Answer 2:

A. Absorbed by the earths surface And

B. Absorbed by celestial bodies.

Explanation:

After entering the Earth atmosphere, the Solar Energy cannot be reflected by the Thermopause or moon. But this energy can be absorbed by the Earth's surface and celestial bodies which will lead to the rise in the temperature of Earth surface and celestial bodies. Also some of the Solar energy is reflected by the earth surface and the celestial bodies back to the atmosphere.

Answer 3:

Both air pressure and wind are simply relative to each other.

Explanation:

Wind is the bulk movement of the air and other gases on the earth. On the other hand if we talk scientifically. Air pressure is the force exerted by the air per unit area of the earth's surface or the atmosphere. The air flows from high pressure to low pressure area which is high at sea level and low at high peaks. Simply wind is the air and other gases present in atmosphere with high air pressure.

Answer 4:

C. Relative humidity

Explanation:

The Person is finding the Relative humidity with the help of the instrument called Psychrometer. A Psychrometer have two temperature sensors: one is  dry bulb and other is wet bulb sensor. The dry bulb sensor of the instrument measures the temperature of the air and the wet bulb sensor measures the temperature of moisture present in the air.
