How can an extinction occur quickly?
Species are hunted to extinction.
A natural disaster wipes out an entire species.
Mountains create a geographic divide separating a species from its resources.
Climate changes eliminate the food sources of a species.
Why is the inner core of Earth a solid?
The pressure on the inner core is so great that even substances at 6,000°C remain solid.
The temperature of the inner core is very cold so it remains a solid.
The pressure of the inner core pushing against the mantle keeps it solid.
The inner core is made of solid metal and is impossible to melt.
The illustration shows simple smog-collecting disks at four different locations. Why did scientists choose four different locations instead of a single location?
They wanted to see which disk collected the most smog.
They wanted to collect smog under many different conditions.
They wanted to get consistent results from each location.
They wanted to prove that the most smog is collected in a city.
What kind of climate clues provide evidence Pangaea once existed?
Glacial grooves exist across multiple continents where they once fit together.
Mountain ranges exist on several continents where they once fit together.
Fossil evidence is similar on continents where they once fit together.
Similar animal species exist on multiple continents where they once fit together.
A geologist is trying to determine the relative age of rock layers in a certain area, but he or she cannot rely only on the law of superposition. Which clue will help the geologist determine whether a rock layer has been overturned?
Igneous rock usually forms below sedimentary rock.
Rock layers erode at an average rate of 1.5 m per year.
The largest sediment particles usually are deposited near the bottom of a rock layer.
Metamorphic rocks are the lightest type of rock, so they are located at the top of a rock layer.

control
dependent variable
independent variable
hypothesis
As air in Earth's atmosphere is heated by the Sun, the warmer air expands and becomes less dense than the cooler air. As a result, the warmer air rises and the cooler air sinks. What is the cycle of warm air rising and cool air sinking called?

deep current
convection current

These children are playing tug-of-war, a contest in which each team tugs on a rope to pull the other team across a line. Why does the rope move to the left?
because the net force of the two teams is zero
because the team on the left creates an unbalanced force
because the team on the right does not create enough friction
because the team on the right creates a balanced force
