The diagram represents rock layers in an area. Which could be learned from studying these layers?

• how many organisms have lived on Earth

• how the Earth's core has changed over time

• how many earthquakes have occurred on Earth

• how the Earth's surface has changed over time

Why is nearly 97% of Earth's water unsuitable for consumption by humans?

• because it is too cold

• because it is trapped underground

• because it is too salty

• because it is trapped in ice

Which factor determines the amount of gas that can dissolve in ocean water?

• the temperature of the ocean water

• the motion of the air above the ocean water

• the motion of the ocean currents

• the temperature of the air above the ocean water

The diagram on the left shows layers of rock. The age of each rock layer is listed in the table on the right. suppose a fern fossil is found between Layer Y and Layer Z. During which time range would the fern fossil most likely have formed?

• 2-10 million years ago

• 10-30 million years ago

• 30-50 million years ago

• 50-70 million years ago

A construction company has clear-cut all the plants on the land next to a river. It plans to build many large homes on the land. During construction, there are periods of heavy rain. Large areas of red mud run off into the water, causing the water to become extremely cloudy. Which effect will these mud particles most likely have on life in the river?

• The mud particles will decrease the turbidity of the water, making it more difficult for plants to photosynthesize.

• The mud particles will increase the turbidity of the water, making it less difficult for plants to photosynthesize.

• The mud particles will decrease the turbidity of the water, making it less difficult for plants to photosynthesize.

• The mud particles will increase the turbidity of the water, making it more difficult for plants to photosynthesize.

A lake borders a housing subdivision and a golf course. Over time, algae in the lake begin to grow uncontrollably. Which is the most likely cause of the algal bloom?

• runoff of topsoil from construction on the golf course

• runoff of nitrates from fertlizers applied to the golf course

• runoff of gasoline from roads through the golf course

• runoff of animal waste from pets walked on the golf course

The diagram shows two locations where fossils of similar land-dwelling animals were discovered in the same type of sedimentary rock. If the fossils date back to the early Mesozoic Era, what can most likely be concluded?

• Earth is the same today as it was in the past.

• Both locations were once joined together in the past.

• The organisms are older than the rock layers beneath them.

• The two locations had climates that differed from each other in the past.

Why is the surface temperature of the ocean usually greater than the temperature on the ocean floor?

• The surface of the water receives more sunlight.

• More photosynthetic organisms live near the surface.

• Salinity is higher along the surface of the water.

• The density of the water is higher at the surface.

How can water be monitored to assure it is safe for human consumption?

• by adding extra nitrates and phosphates to the water

• by testing drinking water for chemicals and bacteria

• by incresing the acidity of the water to prevent diseases

• by lowering the dissolved oxygen levels in the water
