two functional areas that absorb harmful radiation from the Sun.

Based on function, the atmosphere has:

earlier; west to east(i.e., counterclockwise)

If City A is located west of City B, the time at City A is __________ than that at City B because the earth rotates from __________ when viewed from above the North Pole.

the ship is 30o west of its home port

If a clock on a ship indicates that it is 2:00 P.M. in its home port, while another clock on the ship indicates that it is 12:00 noon at the ship's present location, what is the difference in longitude between the ship's present position and its home port?

July 4th; 1:00 AM

If it is 10:00 PM on July 3rd at 30 degrees west, what date and time is it at 15 degrees east?

stratosphere and thermosphere

Temperatures increase with increasing altitude (going up) in what two atmospheric layers?

mainly visible light and infrared energy

The Sun produces which of the following?

the interaction of the solar wind and atmospheric gases.

The auroras (borealis and Australis) in the upper atmosphere are caused by:

poorly mixed; the influence of gravity which causes gases of different weight to separate into layers

The heterosphere is the layer of the atmosphere in which the gases are ________ because of __________.

time that the sun is directly overhead at the Tropic of Cancer (summer solstice)

The maximum number of daylight hours of the year in the N. Hemisphere are experienced during the:

the International Date Line.

The meridian opposite of the Earth's prime meridian (0° longitude) is called:

poles

The oblateness of Earth occurs at the

absorbs most ultraviolet wavelengths.

The ozonosphere is critical to life because it:

was first made by Pythagoras, 580-500 B.C.

The realization that the Earth was a sphere

approximately 480 km (300 mi.) above Earth's surface.

The thermopause is located:

Earth's sphericity, which presents varied angles to parallel solar rays.

The uneven distribution of insolation by latitude is primarily caused by:

International Date Line; lose a day (Example: Saturday becomes Sunday.)

Travelers flying west from Los Angeles (118° W) to Tokyo (139° E) will cross the __________ and, as a result, they will __________ when crossing this meridian.

the temperature of the stratosphere prevents tropospheric air from rising into it.

Weather is confined to the troposphere because:

We consider the top of the atmosphere to be 32,000 km (20,000 mi.) from Earth's surface.

Which is not true of Earth's modern atmosphere?

biosphere

Which of the following Earth spheres is considered a living sphere?

All of these statements are correct.

Which of the following accurately describes Earth's distance from the sun?

latitude

Which of the following is easily determined using the position of the Sun or stars such as Polaris?

subantarctic zone - area between 55o and 66.5o latitudes

Which of the following is incorrectly matched regarding latitudinal geographic zones?

aphelion - earth-sun distance is 91.5 million miles

Which of the following is incorrectly matched?

arctic circle - 66.5o southern parallel

Which of the following is incorrectly matched?

It is capable of sustaining life on Earth even though some portions of the spectrum are actually harmful to living organisms.

Which of the following is true of the Sun's electromagnetic spectrum?

It results from chemical reactions with chlorine that is derived from CFCs.

Which of the following is true regarding the depletion of ozone in the ozonosphere (ozone layer)?

both B and C

Which of the following is/are great circle(s)?

nitrogen, oxygen, argon, carbon dioxide, trace gases

Which of the following lists the correct sequence of gases, from most to least, in terms of percentage within the homosphere?

The equatorial diameter is 42 km (26 mi.) greater than the polar diameter.

Which of the following statements about Earth is correct?

both A and C

Which of the following statements is true regarding latitude and parallels?

March 21 = equal day and night hours everywhere on Earth.

Which of the following statements is true?

geoid

Which of the following terms is used to accurately describe the earth's shape?

oxygen

Which of the gases listed below has accumulated in the atmosphere as a result of biological (life) processes?

Earth is an open system.

With respect to air, water, and material resources, which of the following is true about the Earth?

a sunspot.

A magnetic disturbance on the Sun's surface is called:

all of these statements are correct

A map scale of 1:24,000 means that:

longitude

An angular distance measured east or west of the prime meridian from the center of Earth is termed:

latitude.

An angular distance measured north or south of the Equator from the center of Earth is called:

equator.

Earth's circumference is greatest when measured around the

positive; negative

If we burn fossil fuels, which release carbon dioxide and warm the atmosphere, as the oceans warm they will release more carbon dioxide, which warms the atmosphere. This is an example of __________ feedback. If the increased atmospheric carbon dioxide causes increased plant growth which removes carbon dioxide and cools the atmosphere, this is an example of __________ feedback.

insolation.

Intercepted solar radiation is also known as:

the ozonosphere and ionosphere shield the surface from harmful solar radiation.

Life is possible on Earth primarily because:

above the Arctic Circle.

On June 21, the sun never sets at John's location. Based on this, it can be concluded that John lives:
