Energy & the Atmosphere

The method of heat transfer that plays a central role in transferring heat energy within the atmosphere and the ocean is

• radiation.

• conduction.

• reflection.

• convection.

The atmosphere is heated both by the Sun and by the Earth's surface. Water radiates heat differently than land, so the air temperature over the ocean is usually different than the air temperature over land.The difference in air temperature over land compared to over water causes convection currents in the atmosphere. How would a person at the beach experience these convection currents?

• They would feel wind as the air moves.

• They would feel the heat of the Sun.

• They would feel that the water is cold

• They would feel that the sand is hot.

Which of the following is the best description of conduction?

• heat transfer in a gas or liquid by the circulation of currents from one region to another

• the transmission of heat through a medium without the motion of the medium

• the process of changing from a gas to a liquid or from a liquid to a gas

• the emission of energy in the form of rays or waves that can travel through empty space

Some areas of the Earth receive more solar radiation than others. Which of the following results from the Sun's uneven heating of the Earth?

• ocean currents

  climate

  weather

• mountain height

• climate

  moubtain height

• weather

During the day, the earth is heated up by the sun. The land gets hotter than the sea because it takes less energy to increase the land's temperature than to increase the sea's temperature. The land heats the air near it. This air rises and is replaced by cool air from the ocean, creating a "sea" breeze that blows from the ocean to the land during the day.Which forms of heat transfer are described above as helping to create a sea breeze?

• convection and conduction

• convection only

• radiation only

• conduction and radiation

Which of the following is the best description of convection?

• the process of changing from a gas to a liquid or from a liquid to a gas

• the emission of energy in the form of rays or waves that are able to travel through empty space

• the transmission of heat through a medium without the motion of the medium

• heat transfer in a gas or liquid by the circulation of currents from one region to another

  Question 7 .

Global climate and weather patterns are driven by differences in the amount of heat energy in different areas of the Earth. Which statement best explains why different areas of the Earth have different amounts of heat energy?

• The Earth receives different amounts of solar energy in different regions.

• The solar radiation from the Sun is equally distributed across the Earth at all times.

• The gravitational energy from the Sun varies greatly in different regions of the Earth.

• The Earth spins at different rates so the rotational energy of the Earth varies.

  Question 8 .

Convection occurs in the Earth's _______.

• atmosphere

• mantle

• oceans

• all of these

The Sun heats Earth's atmosphere unevenly. This causes convection currents to move in large circles in the atmosphere.What is the result of convection currents in the atmosphere?

• ozone layer

• WIND

• HUMUDITY

• UV isinlari

When the ground gets warm, it emits an invisible type of light called infrared light. This light can travel into the atmosphere and heat the air that it encounters.What type of heat transfer is described above?

• pricipitation

• radiation

• conduction

• convection
