MET Chapter 2 Exam

Earth's current angle of inclination (tilt angle) is:

23.5°

18°N.

Based on the analemma above, where is the sun directly overhead on August 1st?

Which of the following correctly describes the equinoxes?

Days and nights are equal in length in all parts of the world.

The 90° angle rays strike the Tropic of Capricorn on:

December 21.

Arctic Circle.

Identify the name of the indicated parallel of latitude labeled "D."

The length of daylight gets progressively longer going NORTH from the equator on:

June 21.

Early in January the Earth is CLOSER TO THE SUN than at any other time of the year. This position is termed:

perihelion.

The Earth receives energy from the Sun by:

radiation.

The primary factor which determines what type and how much radiation an object emits is its:

temperature.

Which of the following is a measurement of the average kinetic energy possessed by the atoms or molecules in a substance?

temperature.

If an in balance occurs between incoming and outgoing energy at the Earth's surface:

temperatures either increase or decrease.

Most of the solar energy absorbed by planet Earth and its atmosphere is absorbed by:

the Earth's surface.

Clouds play an important role in the Earth's energy budget because they:

- absorb longwave radiation & reradiate it towards the surface. -reflect solar energy. (Both A & C)

40°.

Using on the analemma above, calculate the approximate noon sun angle for a latitude of 40°N on October 20th. Choose the correct answer below.

The atmosphere is heated primarily by:

absorption of Earth's longwave radiation.

The atmosphere is strongly _______ with respect to terrestrial radiation.

absorptive.

The Earth emits terrestrial radiation:

all the time.

In meteorological terminology, the primary difference between convection and advection is:

convection represents vertical heat transfer and advection represents horizontal heat transfer.

Of the following choices, the surface with the HIGHEST albedo is:

fresh snow.

The absorption of longwave radiation by certain gases in the lower atmosphere is responsible for the:

greenhouse effect.

Most of the radiation emitted by the Earth and its atmosphere is in the category of:

infrared.

Which of the following does NOT happen to solar radiation as it passes through the atmosphere?

intensification.

Scattering:

is responsible for the redness of sunsets.

The energy associated with motion is called:

kinetic energy.

The primary cause of Earth's seasons is:

tilt of Earth's rotation axis, which causes sun angles and daylight length to vary.

The atmosphere is highly _______ with respect to solar radiation.

transparent.
