Meteorology Chapter 1

Ninety percent of our atmosphere lies below an altitude of about:

16 Km

Studies have shown that on average ozone depletion is greatest over this area.

Antarctica

What is true of high pressure areas?

Clockwise winds Clear conditions & sinking air

With an increase in altitude, air pressure:

Decreases at a decreasing rate

Which of the following spheres is composed exclusively of water?

Hydrosphere

Water vapor represents what fraction of the air near the earth's surface?

Less than 4%

Which of the following coordinates measure the position of a place East or West of the Prime Meridian (or location of a place relative to the Prime Meridian)?

Longitude

What is the most abundant gas in the atmosphere?

Nitrogen

Which of the following is NOT an example of a variable gas in the atmosphere?

Nitrogen

This atmospheric component absorbs damaging ultraviolet radiation from the Sun.

Ozone

The ozone layer is found in the

Stratosphere

The vertical temperature structure of the troposphere can be described by

The lapse rate

What is an example of climate rather than weather?

The record high temperature for today

In general, what happens to temperature as you go up through the troposphere?

The temperature decreases

Atmospheric pressure is caused by:

The weight of the air above

The hottest layer of the atmosphere is the

Thermosphere

Which of the following is an example of weather rather than climate?

Today's high temperature

The "weather sphere" is in the

Troposphere

The summit of Mt. Everest is found in the

Troposphere

This variable atmospheric component can exist in all three states of matter (solid, liquid, and gas) at the temperatures and pressures that normally exist on Earth.
