Science 9 week review

Look at the picture. Which statement is an inference rather than an observation?

• The ostrich has feathers.

• The ostrich has a long neck.

• The ostrich has a beak.

• The ostrich can run long distances.

Each student in Mr. Stone’s class was asked to cut a green leaf in half. They were given a hand lens to look at the inside of the leaves and to draw what they saw. What is this activity called?

• making an inference

• making a prediction

• making a classification

• making an observation

Which part of the water cycle shows evaporation?

• A

• B

• C

• D

Which part of the water cycle shows condensation?

• A

• B

• C

• D

After rain, snow, sleet, or hail fall on land surfaces, the precipitation returns to the oceans, rivers, ponds, or lakes. This process is called —

• runoff

• condensation

• evaporation

• water vapor

Clouds are made of tiny, liquid-water droplets. They are formed when water vapor--

• moves from a warm place on land to a cool place in the atmosphere and condenses.

• gathers together in large bodies of water like lakes and oceans and bubbles up.

• collects lots of dust and rises to the sky.

• falls from the atmosphere and settles on wind drifts in the air.

A student is recording an observation in her science journal. She describes the clouds over her back yard fence as “spread out all over the sky in lots of layers. The clouds are covering up all of the blue sky. The sun is even covered up.” What type of clouds does she see?

• cirrus

• cumulus

• stratus

• stirrup

If you look outside of your window and see cirrus clouds, you can expect —

• fair weather

• light rain and drizzle

• huge thunder storms

• fast winds

Precipitation comes in many different forms. Water can fall to Earth in the form of rain, sleet, snow, or hail. What determines the form of precipitation?

• the temperature of the air

• the month of the year

• the time of the day

• the movement of the wind current

Why is it important to monitor wind speeds?

• High wind speeds indicate a hurricane is on the way.

• Low wind speeds mean bad weather is moving in.

• High wind speeds can cause damaging side effects like fallen branches.

• Low wind speeds mean conditions are right for storms and floods.
