Question 2: (b) 3.5 billion years ago.

Answer:

Studies of the Precambrian eon have shown that life first appeared on Earth approximately __.(a) 570 million years ago.(b) 3.5 billion years ago.(c) 4.6 billion years ago.(d) 5 billion years ago.

Question 3: (a) cirrus

Cirrus clouds are found at the highest altitudes of all clouds.

Answer:

The clouds that occur at the highest altitudes are called (a) cirrus (b) cumulus

(c) nimbus (d) stratus

Question 4: (b) 3.5 billion years

Life on Earth has existed for approximately 3.5 billion years.

Answer:

Question 5: (b) stratosphere

The ozone layer is found in the upper stratosphere.

Answer:

The ozone layer is found in the (a) troposphere (b) stratosphere (c) mesosphere (d) thermosphere

Question 6: (b) the gravitational pull of the Moon on Earth.

The oceanic tides are caused by the gravitational pull of the Moon on the Earth.

Answer:

Which of the following is most responsible for the oceanic tides?(a) the gravitational pull of the Sun on the Earth (b) the gravitational pull of the Moon on the Earth (c) the heat of the Sun (d) the magnetic pull of the poles

Question 7: (a) horizontal

Air flow in the stratosphere is primarily horizontal. This allows for optimal air circulation at that level.

Answer:

Air flow in the stratosphere is primarily __.(a) horizontal (b) vertical (c) clockwise (d) counterclockwise

Question 8: (c) an inner core of metal

Terrestrial planets have an inner core of metal and a rocky surface. Outer planets have inner cores of ice crystals.

Answer:

Which of the following is a characteristic of terrestrial planets?(a) an inner core made of ice crystals (b) a surface temperature similar to that of Earth (c) an inner core of metal (d) a surface composed of gasses

Question 9: (c) cumulus

The correct answer is (c). Cumulus clouds are often referred to as thunderheads. They have high fluffy peaks that are perfect for generating static electricity and producing thunderstorms.A few scattered cumulus clouds are usually not a threat of a storm, but if several groups of them converge, they could produce heavy rain, thunder and lightning

Answer:

The sky is filled with dark, puffy clouds, and there is a thunderstorm approaching. What type of clouds are you seeing?(a) cirrus (b) stratus (c) cumulus (d) stratocumulus

Question 10: (c) nitrogen

Nitrogen accounts for about 77 percent of the composition of the atmosphere.

Answer:

The most common element in the Earth's atmosphere is __.(a) helium (b) hydrogen (c) nitrogen (d) oxygen

Question 11: (a) Mars

Terrestrial planets are those closest in composition to the Earth. Not surprisingly, they are also the inner planets and those closest in proximity to the Earth. Terrestrial planets have an inner core of metal and rocky surfaces similar to the Earth, though their atmospheric characteristic can be vastly different from the Earth.

Answer:

Which of the following is a terrestrial planet?(a) Mars (b) Jupiter

(c) Saturn (d) Neptune

Question 12: (c) pumice

Choice (c) is correct. Pumice comes from volcanic rock when it cools very quickly on the surface. The small air bubbles formed in it are visible to the naked eye. The bubbles give it its lightweight feel and increase its usefulness in many everyday products.

Answer:

Which of the following is an igneous rock?(a) marble (b) gypsum (c) pumice (d) coal

Question 13: (d) nitrogen

The air in the troposphere is approximately 79% nitrogen and 21% oxygen. This is the layer of air closest to the Earth's surface.

Answer:

The air in the troposphere is made up primarily of __.(a) oxygen (b) helium (c) carbon dioxide (d) nitrogen

Question 14: (a) meteor

A "falling star" is a meteor seen when a meteoroid is burning up in the Earth's atmosphere. If the meteoroid reaches reaches the surface of the Earth, it is then called a meteorite.

Answer:

A "falling star" is also known as a (a) meteor (b) asteroid (c) comet (d) meteorite

Question 15: (a) transpiration

The correct answer is (a). Water enters the atmosphere through the process of transpiration and evaporation. TRANSPIRATION specifically refers to water movement through plants.CONDENSATION happens when water vapor condenses together to form PRECIPITATION, which then falls back the Earth as rain or snow. SEEPAGE is the movement of water through soil.

Answer:
