The black line on the map shows where a continent and an ocean meet. The graph shows the amount of igneous rocks compared to other rock types a scientist finds in the area along the black line. Which claim does this information support?
The food web shows a stable ecosystem. How will the introduction of an invasive species that only eats caterpillars affect the ecosystem?
Look at the picture of cracks in a rock. Which term describes the natural process that most likely caused the cracks?
Students describe why water is a renewable or a nonrenewable resource.
_______________________________________________________________________________________________
1. Water is nonrenewable because it cannot be used if it does not rain.
2. Water is nonrenewable because it is frozen in glaciers and cannot be used.
3. Water is renewable because it moves through the water cycle continuously.
4. Water is renewable because it can be reused.
5. Water is renewable because it can run out and never be replaced.
_______________________________________________________________________________________________
Which statements correctly describe water as a renewable or nonrenewable resource?
The graph shows the human population and the number of forests cut down to make room for farming from 1950 to 2010. Which change can decrease the loss of forested regions while still supporting the human population with food?
Humans also cut down trees to make room for buildings and to use the wood for building materials. Which table shows an improvement humans can make and how that improvement will affect the land?
Where do most earthquakes happen?
A food chain is shown. What do the arrows in the food chain tell scientist?
A food chain is shown. How should the snake be identified in the food chain?
The image shows the formation of a sand dune over a period of time. Which process explains the formation of the sand dune?
A farmer uses chemical fertilizers to increase the number of plants that are grown on a farm. When the plants are watered, the runoff from the farm carries the chemicals to nearby sources of water, polluting the water. The farmer wants a solution that can increase the number of plants without causing any harm to the environment. The farmer tries using natural fertilizer made of animal waste. The chart lists the results.
_______________________________________________________________________________________________• less chemicals in nearby sources of water
• increased number of plants grown
• harmful levels of bacteria found in nearby sources of water
_______________________________________________________________________________________________Is using natural fertilizer the best solution for the farmer?
Soil organisms, like worms, create tunnels through soil, creating spaces and breaking down materials in the soil. A student claims that soil organisms play an important role for healthy soil that helps plants grow. The student lists information to support the claim in a chart. __________________________________________________________________________________________________________
1. Soil organisms make it easier for water to move through the soil.
2. Soil organisms change materials into nutrients.
3. Soil organisms help with the removal of soil by water and wind.
4. Soil organisms allow roots to move deep into the soil. __________________________________________________________________________________________________________ Which information from the chart correctly supports the student’s claim?
Examine the food web. If the rabbit population decreases, which population of organisms will increase first?
Which energy resource is nonrenewable?
Which best supports the claim that photosynthesis occurred in all three test tubes?
Which solution best decreases soil erosion caused by wind on the farms using natural materials without causing harm to the environment?
The image shows a food web. Which organism in the food web is a decomposer?
The image shows the organisms in a pond ecosystem. After a long period of time without rain, the pond water dries up. Which organism from the pond ecosystem will best survive this change, and why?
