ASVAB (General Science - Earth and
Space Science Practice Questions)
And All Correct Answers.
(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.
(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
(c) dead algae decomposing - Answer Which of the following is a way in which carbon is
released into the atmosphere?
(a) pine tree engaging in photosynthesis
(b) sediment settling in the ocean
(c) dead algae decomposing
(d) new plants growing in a forest
(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 During the water cycle, water enters the atmosphere as gas through __.
(a) transpiration
(b) condensation
(c) precipitation
(d) seepage
(b) freezing rain
Warm air fronts generally result in some form of precipitation, though not a full blown storm
like a hurricane (which is a specialized storm that develops over warm ocean water). A sudden
change in temperature is the result of a cold air front and a stalemate is caused by a stationary
front. - Answer The weather report indicates a warm air front is moving in. Which of the
following is most likely to occur as a result of that warm air front?
(a) a sudden change in temperature
(b) freezing rain
(c) hurricanes
(d) weather stalemate
(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
(c) an inner core of metal
