Conduction is the transfer of heat by

• direct contact between 2 objects.

• hot fluids rising and cool fluids sinking.

• electromagnetic waves.

Which of the following is an example of heat transfer through conduction?

• You are standing near a fire place. You can feel the heat traveling through the air to you.

• You are holding an ice cube and it melts.

Where can Earth's atmosphere be heated by conduction?

• In the upper atmosphere, where warm air rises and cooler air sinks.

• On the surface of the Earth, where the air is touching the surface of the Earth.

How is heat transferred through conduction on Earth's surface?

• Warmer, less dense air rises and cooler, more dense air sinks.

• Heat is transferred through electromagnetic waves from the ground to the air above it.

• Faster moving molecules on Earth's surface transfer heat to slower moving molecules in the air above it.

Why is air warmer near Earth's surface?

• The sun heats Earth's surface and in turn the air above it is heated.

• Warm air is more dense and sits on top of the Earth's surface.

• Warm air is less dense and sits on Earth's surface.

When convection occurs in the atmosphere:

• warm air sinks and cool air rises.

• warm air rises and cool air sinks.

• warm air sinks and cool air sinks.

• warm air rises and cool air rises.
