When energy from the sun reaches the air above land, the air warms and rises. Along a coastline, cooler air above the ocean flows toward the land to replace this rising air.

Which of the following best describe these processes?

• Conduction and convection

• Radiation and convection

• Conduction, convection, and radiation

• Radiation and conduction

Vivian placed an ice cube in a tray of warm water. The following picture shows her investigation. Which statement describes the energy transfer that happens in Vivian’s investigation?

• Energy in the form of heat is transferred from the ice cube to the water by radiation.

• Energy in the form of heat is transferred from the water to the ice cube by radiation.

• Energy in the form of heat is transferred from the ice cube to the water by conduction.

• Energy in the form of heat is transferred from the water to the ice cube by conduction

Kumar is studying how Earth is warmed by sunlight. The following illustration shows his model of the sun and Earth.

Which process is mostly responsible for warming the soil in Kumar’s model?

• Conduction between the lamp and the soil causes the soil to warm.

• Convection currents between the lamp and the soil cause the soil to warm.

• Expansion of particles in the soil causes the soil to warm.

• Radiation from the lamp reaches the soil and causes the soil to warm.

Sarah is investigating the transfer of energy in the form of heat. One process that transfers energy between two objects is conduction.

Which statement is NOT true about conduction?

• It involves a transfer of energy in the form of heat.

• It can transfer energy through empty space.

• It requires direct contact between the objects.

• It results in a change of temperature in both objects.

A warm rock is in direct contact with the cooler ground.

Which of the following will happen?

• Energy in the form of heat will flow from the rock to the ground, and the temperature of the rock will increase

• Energy in the form of heat will flow from the ground to the rock, and the temperature of the rock will increase

• Energy in the form of heat will flow from the rock to the ground, and the temperature of the rock will decrease.

• Energy in the form of heat will flow from the ground to the rock, and the temperature of the rock will decrease.

If you visit the beach on a hot summer day you will probably feel a sea breeze coming off the water onto the land.

Which of the following causes this sea breeze?

• During the day, solar radiation warms the land more than the water.

• The water is warmer than the land during the day.

• Earth is tilted toward the Sun, causing air to move inland from the water.

• Hurricanes that form in the oceans blow air into the shore.
