Sediments are transported at different speeds. Which type of sediment transport is the slowest?

• Transport by rivers

• Transport by winds

• Transport by glaciers

• Transport by ocean currents

The raccoon can be found in most areas of Texas. The coati has a smaller territory and is found from Big Bend to Brownsville. These two species are related. The chart shows the characteristics of these two species. Which statement does NOT describe how the body structures of these animals help them escape predators?

• Paws with long claws on flexible toes help them climb trees.

• Sharp teeth allow them to catch prey on land or in water.

• Long tails allow them to balance on branches in trees.

• Good eyesight helps them to see at night.

Deltas are large landforms found along coastlines. What process forms deltas?

• Cementation of sediments by rivers

• Deposition of sediments by rivers

• Erosion of sediments by ocean waves

• Deposition of sediments by ocean waves

A student’s model of a closed ecosystem is shown. The student plans to add land snails to the model in order to show how the snails interact with different parts of the ecosystem. What should the student add to the model so that the snails will survive?

• Fish to provide food

• Sticks to provide a place to hide

• Deep water to provide carbon dioxide

• Living plants to provide oxygen

A group of students is given four small cubes of the same size and instructed to place them in a beaker of water. One cube floats to the surface of the water. Two of the cubes float in the middle of the beaker under the surface of the water. The last cube sinks to the bottom of the beaker. Which conclusion is best supported by what the students observed?

• Two of the four cubes are soluble in water.

• All four cubes have different masses.

• Each cube is made of a different type of solid material.

• One of the cubes is more dense than the other three.
