ELS QUIZ 5

What process by which heat is directly transmitted through a substance when there is a difference of temperature or between adjoining regions, without movement of the material?

• conduction

• convection

• insolation

• radiation

Why radioactive decay plays a significant role in Earth’s internal heat?

• Radioactive element can be found anywhere in the planet.

• When radioactive element decays, it produces heat.

• Spontaneous nuclear disintegration of radioactive elements produced thermal energy.

• All of the above

Which of the following is described as the process of heat exchange between the Sun and the Earth that controls the temperatures of the latter?

• conduction

• convection

• insolation

• radiation

What is produced by the radioactive decay of isotopes in the mantle and crust?

• radiogenic heat

• primordial heat

• superheating

• heat from the sun

How the conduction in the surface of the earth affect the temperature of our atmosphere?

• Air molecules come in contact with the warmer surface of the land and ocean resulting to the increase of its thermal energy.

• Air molecules come in contact with the cooler surface of the land and ocean resulting to the decrease of its thermal energy.

• Air molecules do not come in contact with the warmer surface of the land and ocean resulting to the increase of its thermal energy.

• Air molecules do not come in contact with the cooler surface of the land and ocean resulting to the increase of its thermal energy.

What are the two factors that affects conduction on the Earth’s surface?

• radioactive decay and nuclear disintegration of elements

• heat from the Earth's core and radiation from the Sun

• movement of plates and radiation from the Earth’s core

• stored magma and volcanic eruption

What kind of process by which heat energy is transmitted through collisions between neighboring atoms or molecules?

• conduction

• convection

• insolation

• radiation

What kind of heat transfer occurs mostly on the Earth’s surface?

• conduction

• convection

• insolation

• radiation

How does the mantle behave as a viscous fluid on a geological time scale?

• radiation

• pressure

• temperature

• altitude

What refers to the shaking of the surface of the Earth resulting from a sudden release of energy caused by a convection current?

• earthquake

• volcanic eruption

• storm surge

• hurricane
