Which of the following best describes the greenhouse effect on Earth?

• The greenhouse effect is the ‘trapping’ of some of the Earth’s infrared

  radiation in the atmosphere.

• The greenhouse effect gives the sky its blue colour and the sea its blue-green

  colour.

• The greenhouse effect is the result of industrial pollution and human-caused

  fires.

• The greenhouse effect is caused by the hole in the ozone layer.

Which answer best completes the following sentence correctly? The greenhouse

effect is necessary for life on Earth because:

• it provides the carbon dioxide necessary for plants to photosynthesise.

• it provides us with the oxygen gas we need for life.

• it shields us from the Sun’s ultraviolet radiation.

• it helps keep the temperature of the Earth not too hot and not too cold.

This type of radiation from the sun is related to climate change:

• Infra-red

• Ultra violet

Energy sources that can be replenished by nature in a relatively short period of time

are called renewable energy forms.

Consider the following situations:

Situation 1: A cold spoon is placed in a cup of hot tea.

Situation 2: An ice cube is placed in a cup of hot tea.

Is energy being transferred in either of these situations?

• Energy is transferred when an ice cube is placed in a cup of hot tea, but

  energy is NOT transferred when a cold spoon is placed in a cup of hot tea.

• Energy is transferred when a cold spoon is placed in a cup of hot tea, but

  energy is NOT transferred when an ice cube is placed in a cup of hot tea.

• Energy is transferred in both situations.

• Energy is NOT transferred in either situation.

Which of the diagrams below is an example of the transformation of gravitational

potential energy into motion energy (kinetic energy)?

• 
• 
• 
• 

The particles in a solid that is heating up move farther and farther apart because:

• the particles slow down.

• the particles begin to lose their shape.

• the particles repel each other more intensely.

• the particles have more energy and bump into each other more often

Which of the following has thermal energy?

• A piece of metal that feels cold but not a piece of metal that feels hot.

• A piece of metal that feels hot but not a piece of metal that feels cold.

• Both a piece of metal that feels hot and a piece of metal that feels cold.

• Neither a piece of metal that feels hot nor a piece of metal that feels cold.
