down the ramp?

• The wheels on the skateboard rub on the ramp.

• The weight on the skateboard slows the skateboarder.

• Air from behind pushes the skateboarder.

• Gravity pulls the skateboarder down the ramp.

A student grows a flower near a sunny window and gives it water. After some time,

the plant grows tall and makes seeds.

Which two plant parts helped it grow and make seeds?

• The stem holds up the plant and moves water to other parts.

• The leaves use sunlight to give the plant energy.

• The roots make flowers with petals underground.

• The tall plant drops its seeds as soon as it grows.

• The bark keeps animals away and makes seeds inside the branches.

The table shows water levels in lakes during summer months. It also lists

Which two descriptions use the table to show that the atmosphere and the hydrosphere

affect each other?

• When temperature increases, lake water levels decrease.

• When temperature increases, lake water levels increase.

• Rainfall increases in hotter months. This causes water levels to get higher.

• Evaporation increases in hotter months. This causes water levels to lower.

• When temperature decreases, lake water levels decrease.

• Sticking to a magnet is called magnetism.

• Sticking to a magnet is called conductivity.

• This is a changing property.

• This is a fixed property.

What is an example of an internal structure that helps an animal breathe?

• skin

• fur

A city planner is looking for ways to help the city during large amounts of rain.

Which argument explains the solution that will best deal with heavy rain?

• The city should only build short buildings. People in the city will have better views of thunderstorms.

• The city should use pavement that allows water to soak through. Extra water will have a place to go

  during heavy rain.

• The city should build more parking lots. They will give water a place to pool during heavy rain.

• The city should remove storm drains. The city will save money that can be used to repair flooding

  damage.

The model shows how the Earth’s spheres affect each other. The biosphere is shown

with a tree.

Which statement best explains how the trees works with the other spheres?

• The tree takes sunlight from the atmosphere. The tree pulls up water from the hydrosphere. The tree

  grows in the soil of the geosphere.

• The tree gets nutrients from the atmosphere. The tree pulls in water from the geosphere. The tree

  grows in the hydrosphere.

• The tree pulls in water vapor from the atmosphere. The tree gets minerals from the hydrosphere. The

  tree gives off gases into the geosphere.

• The tree gives water to the geosphere. The tree gets gasses from the hydrosphere. The tree drops dead

  leaves in the atmosphere.
