Earth's Atmosphere
According to naturalistic scientists, which gas that is currently found in our atmosphere was NOT present in the earth's earliest atmosphere?
oxygen
What does a barometer measure?
atmospheric pressure
A large body of air in the troposphere with fairly uniform temperature and humidity conditions, which it obtained in its source region.
air mass
The climate zone of the Australian Outback
dry
The most prevalent greenhouse gas in the atmosphere is ______________.
water vapor
Where do plants get their carbon as part of the carbon cycle?
atmosphere
Which type of cloud never produces rain?
cirrus
The boundary between two distinct air masses.
front
polar
Over the past fifty years, the earth's average temperature has probably ___________ by ___C to ____ C.
increased; .05C to .08C
Soil and marine bacteria convert molecular atmospheric nitrogen (N2) into a organic nitrogen compound such as ammonia (NH3) that is usable by plants. This process is called _____________.
nitrogen fixing
Wind blows from areas of ___________ to areas of _____________.
high pressure; low pressure
A _____________ occurs when a warmer air mass is replacing a colder air mass.
warm front
Climate zone of the Mediterranean coast of Europe
temperate marine
Major volcanic eruptions or dust storms can _______ the earth's average temperature for _______ or more.
decrease; a year
Most of Earth's weather happens in the ________ (up to 11km above the Earth's surface).
troposphere
If the dew point high in the troposphere is -3C, then the pollen grains and dust particles there will act as ___________.
freezing nuclei
When an air mass moves across a body of water, gaining moisture and dropping it as snow.
lake effect
Climate zone of the forests of the US Great Lakes region.
What do secular scientists and young-earth creation scientists agree on about climate change?
The earth has experienced climate change in the past.
The most significant difference between the heterosphere (below 80km) and the homosphere (above 80km).
In the heterosphere gases separate into layers on the basis of their masses. In the homosphere the gases stay uniformly mixed.
What causes sea breezes?
During the day the land absorbs the sun's energy more rapidly than the water does, so the wind blows from the cool ocean toward the warm land. At night the land cools off faster than the water does, so the wind blows from the cool land toward the warm water.
What happens when two air masses meet?
Climate zone of the African savanna.
tropical rainy
What is a young-earth view of ice ages in earth's history?
There was one major ice age (after the Flood) followed by a series of mini ice ages.
