1
The Green Revolution contributed to a population explosion due to research
and technology breakthroughs in the mid-1900s.
Select one statement that is NOT a result of these breakthroughs.
Fertilizers were chemically produced, which improved food supplies.
Improvements to agricultural crops increased production worldwide.
All nations became stronger and more self-sufficient as the population
increased.
Advances were made in sanitation and medicine that improved lives.
CONCEPT
Human Arrival and Expansion
2
Plant and animal life faced many challenges when moving from water to
land.
Select the FALSE statement about this transition.
Organisms on land could dry out unless they found a water source.
Organisms’ movements changed without water for transport.
The development of an ozone layer protected organisms from solar radiation.
Oxygen levels in the atmosphere were not high enough to sustain life on
land.
CONCEPT
, Early Life
3
Choose the factor below that is likely to have led to the greatest
number of mass extinctions.
Temperature change
Earthquakes
Asteroids
UV radiation
CONCEPT
Continental Drift and Major Extinctions
4
Choose the statement that correctly defines continental drift.
Tectonic plates and the continents they formed are unmoving and remain in
the same position.
Continents were formed by tectonic plates that lie on the molten core of the
Earth.
Tectonic plates cover the Earth’s molten core; when one rose above the
water, it became a continent.
Continents are the surfaces of constantly moving tectonic plates that float on
the Earth’s molten core.
CONCEPT
Continental Drift and Major Extinctions
5
Ecosystems provide many benefits to humans, which are termed "ecosystem
services."
