Exam 1: Earth and Its Atmosphere

These sayings are based on close observations, and most likely have some truths in them, but they are not based on the scientific method. -Fronts are a sharp change in temperature,humidity,and wind direction.

The Sun is surrounded by Earth,and how many other planets?

On weather maps cold fronts are drawn

The rate at which temperature decreases with increasing altitude is known as the

The difference in atmospheric density is greatest in the layer bounded by

A(n)____________________ is an intense rotating column of air that extends downward from the base of a thunderstorm with a circulation reaching the ground.

What causes air pressure? Why does air pressure decrease with increasing altitude?

These sayings are based on close observations, and most likely have some truths in them, but they are not based on the scientific method. -Storms rank in size from largest to smallest,as follows: middle-latitude cyclonic storm,hurricane,thunderstorm,tornado.

These sayings are based on close observations, and most likely have some truths in them, but they are not based on the scientific method. -Of the four most abundant gases in our atmosphere,water vapor shows the greatest variation at Earth's surface?

The average surface temperature on Earth is

These sayings are based on close observations, and most likely have some truths in them, but they are not based on the scientific method. -On the basis of temperature,the layers of the atmosphere from the lowest layer to the highest are the thermosphere,mesosphere,stratosphere,and troposphere.

These sayings are based on close observations, and most likely have some truths in them, but they are not based on the scientific method. -Carbon dioxide is a naturally occurring component of the atmosphere.

The ____________________ of air in a rigid container is the same everywhere in the universe.

The average or standard ____________________ in the troposphere is about 6.5°C for every 1000 m or about 3.6°F for every 1000 ft rise in elevation.

The atmosphere protects inhabitants at Earth's ____________________.

These sayings are based on close observations, and most likely have some truths in them, but they are not based on the scientific method. -The ozone hole is an actual hole in the atmosphere,a region of complete vacuum.

The concentration of ____________________ is close to 21 percent (by volume)in the upper stratosphere (the same concentration as in the trophosphere),but without proper breathing apparatus you would not be able to survive there.

Chinook winds are

Describe some of the processes that release and remove carbon dioxide from the atmosphere.Is there any evidence that suggests that these processes are not in balance?

Under what circumstances might a person breathe stratospheric air? How often is it likely to happen in a student's lifetime?
