تدريب عام: Unit 3 : Concept 3.1 Energy Transfer through the Water Cycle (Science) - Primary 6 - Science

السؤال 1

Why are flamingos particularly vulnerable to changes in the salt lake ecosystem?

Their food source and breeding habitat are directly dependent on the lake's water levels.

They prefer deep, fast-moving water.

They consume a wide variety of food types.

They can easily migrate to any new aquatic environment.

السؤال 2

The motion of air from one place to another can lead to the change of liquid water into water vapor.

False

True

السؤال 3

How is heat energy primarily transferred throughout Earth's atmosphere to drive the water cycle?

Conduction directly transfers heat from the sun to the ground.

Radiation is the sole method of heat transfer within the atmosphere.

Latent heat is released when water freezes, warming the atmosphere.

Convection currents circulate warm, moist air and sinking cold fluid.

السؤال 4

What is a key objective for students learning about the water cycle?

To calculate the exact volume of water in all oceans.

To memorize the names of all cloud types.

To develop a model describing its components and predicting changes.

To identify only the coldest regions of Earth.

السؤال 5

The water cycle describes a process where nature recycles water through continuous movement.

False

True

السؤال 6

Earth's rotation significantly influences the direction of global winds.

False

True

السؤال 7

Rivers are involved in the water cycle by collecting precipitation and channeling it towards larger bodies of water.

False

True

السؤال 8

What percentage of water vapor in the air originates from transpiration?

About 90 percent

About 1 percent

About 50 percent

About 10 percent

السؤال 9

Water vapor in the atmosphere is typically visible to the naked eye.

False

True

السؤال 10

How does gravity influence water movement within glaciers?

Gravity causes glaciers to instantly melt into liquid water.

Gravity lifts glaciers to higher altitudes.

Gravity causes solid water to flow from higher to lower elevations.

Gravity traps water permanently within glaciers.

السؤال 11

How does the dry air, formed after warm air rises, moves away, and descends, contribute to Earth's climate features?

It contributes to the formation of deserts around the planet.

It leads to continuous precipitation in those regions.

It fosters lush, tropical ecosystems upon descent.

It immediately re-absorbs water vapor, causing humidity.

السؤال 12

The water cycle primarily involves the movement of salty water from oceans to the atmosphere.

False

True

السؤال 13

Gravity plays no significant role in the water cycle once water is in the atmosphere.

False

True

السؤال 14

What are the primary natural forces that drive energy transfer and movement within the water cycle?

Only evaporation and condensation influence the water cycle.

The Coriolis effect is the sole force responsible for water movement.

Volcanic activity and plate tectonics are the main drivers.

Sunlight, convection, gravity, and wind are fundamental forces.

السؤال 15

Plants contribute to the water cycle by releasing water vapor into the atmosphere.

False

True
