What gas needed to be established within the Earth's atmosphere before the atmosphere was able to absorb and maintain heat?
Nitrogen
Carbon dioxide
Oxygen
Hydrogen
Which event followed a massive volcanic eruption and led to the cooling of global temperatures?
the release of carbon dioxide and methane gases
thunderstorms that developed near the eruption
the outflow of magma over Earth’s surface
the addition of ash particles into the atmosphere
Most of the molecular oxygen in the early atmosphere of Earth resulted from:
lightning striking Earth
photosynthesis in primitive plants
volcanic eruptions
decaying primitive plants and animals
Which of the following was primarily responsible for the development of life outside of the oceans?
A decrease in atmospheric carbon dioxide
An increase in atmospheric oxygen
An increase in atmospheric nitrogen
A decrease in atmospheric hydrogen
Where is the majority of O3 found in the Earth's atmosphere?
Mesosphere
Troposphere
Stratosphere
Thermosphere
Most scientists believe Earth’s Early Archean atmosphere was formed primarily by gases released from:
volcanic eruptions
stream erosion
chemical weathering
plant transpiration
The composition of Earth's atmosphere has changed over geologic time. Early cyanobacteria performed photosynthesis contributing which chemical to the early atmosphere?
Freon
Oxygen
Carbon dioxide
Methane
Fossil evidence indicates that the earliest forms of life that appeared on Earth were most likely —
bacteria
trilobites
protists
diatoms
About 2.0 billion years ago, complex organisms began to inhabit Earth. These complex organisms developed primarily because of —
sunlight being absorbed by land
the eruption of volcanoes
changes in atmosphere gases
the impact of comets
What layer of the atmosphere is labeled number 1?
Thermosphere
Troposphere
Mesosphere
Stratosphere
Cloudy nights can be warmer than clear nights because clouds trap heat —
produced by the friction of air particles
absorbed by Earth during daylight hours
released from Earth’s interior
generated from tropical winds
Which natural process is the main cause of the ocean currents shown?
Drift of continents
Evaporation
Orbit of Earth
Convection
What contributes to the formation of hurricanes during the late summer?
the interaction between ocean water salinity and warm air masses
the interaction between ocean water salinity and ocean water density
the interaction between ocean water temperatures and warm air masses.
the interaction between ocean water currents and polar air masses
Which of these statements is best illustrated by this diagram?
Water- dwelling animals breathe carbon dioxide.
Animals under water eat plants.
Plants can take in carbon dioxide from air or water
Land animals exhale oxygen into water
Ozone molecules protect Earth from the harmful effects of the sun by—
regulating the heat from the sun
insulating the temperature at the poles
absorbing ultraviolet radiation
condensing water particles in clouds
What long-term impact could the destruction of large areas of forests have on Earth?
decreased rates of erosion
increased atmospheric oxygen levels
decreased amounts of acid rain
increased atmospheric carbon dioxide levels
Biologic activity can change the amount of —
salinity in the ocean
silicon in the ocean
oxygen in the air
water on the earth
