Understanding Energy Transfer in the Atmosphere

What happens when warm air carrying humidity moves over a cooler pond?

• The pond heats the air

• The air loses its humidity and creates fog

• The air temperature remains the same

• The pond becomes less humid

What is the primary source of energy discussed in radiation?

• Wind energy

• Geothermal energy

• Hydroelectric energy

• Solar energy

How does conduction occur according to the example given?

• Through movement of air only

• Through direct contact between two objects

• Through electrical currents

• Through heat from the sun

What is the role of the sun's rays in heating the sand at the beach?

• The rays cool down the sand

• The rays increase moisture in the sand

• The rays cause the sand atoms to vibrate and generate heat

• The rays have no effect on the sand

What happens when the sand grains at the beach heat up?

• They absorb water from the air

• They start to move around

• They cause the air above them to heat up

• They turn into glass

What causes the air balloon to rise according to the explanation of convection?

• Decreased air pressure inside the balloon

• Increased heat causing lower density of air

• Higher air pressure outside the balloon

• Cooling of the air inside the balloon

Which example illustrates conduction?

• Sun heating the sand

• Sunlight in a cold area

• Hands warming on a hot cup

• Air balloon rising

How does the air's density change when it heats up?

• It fluctuates rapidly

• It stays the same

• It decreases

• It increases

What is the memory trick for remembering radiation?

• Thinking of 'Ray' from 'radiation' which relates to the sun's rays

• Associating it with 'radical' movements

• Linking it to 'radio' waves

• Remembering it as 'random' energy transfer

What does convection involve according to the lesson?

• Direct contact of heat

• Movement of heat in a cyclic pattern

• Radiation from the sun

• Static air conditions
