The inner core's magnetic field pushes the plates.

Answer

The outer core's liquid state allows the plates to float.

Question 10

Accepted Answer

Conduction

Answer

Convection

Answer

Radiation

Answer

Reflection

Question 11

Describe the process of convection and how it affects weather patterns.

Accepted Answer

Convection involves the transfer of heat through fluid movement and affects weather by creating wind and storm systems.

Answer

Convection involves the transfer of heat through direct contact and affects weather by warming the surface.

Answer

Convection involves the transfer of heat through electromagnetic waves and affects weather by heating the atmosphere.

Answer

Convection involves the transfer of heat through reflection and affects weather by cooling the surface.

Question 12

Compare and contrast the functions of the respiratory and circulatory systems in the human body.

Accepted Answer

Both systems are involved in gas exchange; the respiratory system brings in oxygen and removes carbon dioxide, while the circulatory system transports these gases to and from cells.

Answer

Both systems are involved in digestion; the respiratory system breaks down food, and the circulatory system transports nutrients.

Answer

Both systems are involved in waste removal; the respiratory system removes carbon dioxide, and the circulatory system removes solid waste.

Answer

Both systems are involved in movement; the respiratory system moves air, and the circulatory system moves blood.

Question 13

What is the main function of the nucleus in a cell?

Accepted Answer

To control cell activities

Answer

To produce energy

Answer

To synthesize proteins

Answer

To store water and nutrients

Question 14

The water cycle describes the continuous movement of water on, above, and below the surface of the Earth. The fundamental process of the water cycle can be modeled to illustrate the most important aspects of the natural phenomenon. The water cycle involves the exchange of energy, which leads to temperature changes. When water evaporates, energy is removed which cools the environment. When water condenses, it releases energy and warms the environment. In addition, the water cycle transfers water from one system to another. The water cycle purifies water, replenishes the land with freshwater, and transports minerals to different parts of the globe. But, most importantly the water cycle is crucial in the maintenance of life and the ecosystems of Earth. Study the diagram. What cause and effect prediction can be used to test the assumptions in the model?

Accepted Answer

evaporation will cause the temperature to decrease in the system

Answer

condensation will cause the temperature to decrease in the system

Answer

evaporation does not effect temperature change in the system

Answer

condensation does not effect temperature change in the system

Question 15

Fossils of a now extinct dinosaur have been found near the east coast of South America and the west coast of Africa. The dinosaur could not swim or fly. What does this suggest about the continents of South America and Africa?

Accepted Answer

The continents were once connected.

Answer

A land bridge once connected the continents.

Answer

The same type of animals evolved on both continents.

Answer

Prehistoric man transported the dinosaur between the continents.

Question 16

Crustal plate movement occurs because the Earth's mantle flows as a result of uneven heating inside the mantle. Convection cells are created by very hot material deep in the mantle rising, then cooling, sinking again, and then heating again and then repeating the cycle. This process occurs because of the energy generated by _________________ within the Earth.

Accepted Answer

radioactive decay of elements

Answer

differences in densities

Answer

solar radiation

Answer

plate convergence

Question 17

Why might a scientist repeat an experiment if she/he didn't make a mistake in the first one? Experiments are repeated to
