Heat and Water Cycle Quiz

Rays from the sun are shining down on a house, as shown in the illustration. What effect does the sun have on the temperature of the house?

• The temperature of the house increases because heat radiates from the sun.

• The temperature of the house increases because heat is conducted by the sun.

• The temperature of the house decreases because heat is convected by the sun.

• The temperature of the house decreases because the sun absorbs heat from the house.

The area in front of a fire feels warm on a cold evening. What are the processes that cause the person in front of the fire to feel warm?

• conduction and convection

• radiation and conduction

• radiation and convection

• radiation, convection, and conduction

What conditions are necessary for heat conduction to occur between two objects?

• The objects must be surrounded by air or water.

• Two objects at different temperatures are touching one another.

• Two objects at different temperatures are located close to one another.

• One object must emit energy as light and heat and another object absorbs the energy.

Which best describes how heat moves from one solid to another solid?

• through conduction

• through convection

• through insulation

• through radiation

Which best describes how heat is transferred due to convection?

• through direct contact with a hot object

• through the movement of gases or liquids

• through the absorption of the sun’s energy

• through the process of liquid changing into a gas

Manuel was having trouble opening a new glass jar of pickles. His father told Manuel to hold the metal lid of the jar under running hot water for a few seconds, then try again. Then the lid opened easily. What is the MOST likely reason Manuel’s father suggested using hot water to loosen the lid?

• Glass contracts when it is heated.

• Metals expand when they are heated.

• Metals are easier to grip when they are warm.

• Hot water reduces friction between metal and glass.

Uneven heating of Earth causes convection currents. What part of this process is being demonstrated in this diagram?

• Heat causes gases to expand.

• Heat causes gases to contract.

• As air cools, currents flow clockwise.

• As air cools, currents flow counterclockwise.

Which best describes the flow of heat?

• from a larger object to a smaller object

• from a warmer object to a cooler object

• from a cooler object to a warmer object

• from a smaller object to a larger object

Josiah is going to have a cup of hot cocoa. If he wants the cocoa to stay warm as long as possible, which type of cup should he put his hot cocoa in?

• An iron cup because it is a conductor

• A foam cup because it is an insulator

• A metal cup because it is an insulator

• A glass cup because it is a conductor

Why do asphalt streets often have cracks in them?

• because asphalt is a good conductor of heat

• because asphalt expands when heated and contracts when cooled

• because asphalt is an insulator that helps keep heat from escaping

• because asphalt contracts when heated and expands when cooled
