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

السؤال 1

Which statement accurately describes the process of convection?

Convection is the transfer of heat through electromagnetic waves.

Convection involves the direct transfer of heat through stationary materials.

Convection occurs when cold particles rise and hot particles sink due to density changes.

Convection is movement where hotter, less dense fluid particles rise, and cooler, denser fluid particles sink.

السؤال 2

What happens to water vapor when warm air containing it rises and cools?

It loses this water in the form of rain.

It gains more water vapor, becoming super-saturated.

It permanently stays in the upper atmosphere.

It becomes denser and immediately falls back down.

السؤال 3

How does the density of a liquid or gas change when it is heated?

It stays the same density.

It solidifies and increases density.

It contracts and becomes more dense.

It expands and becomes less dense.

السؤال 4

Which process is directly responsible for the formation of clouds in the atmosphere?

Transpiration

Condensation

Evaporation

Precipitation

السؤال 5

Freezing is a process that releases thermal energy as water changes from a liquid to a solid state.

False

True

السؤال 6

Which process involves water changing from a liquid to a gas due to heat absorption?

Condensation

Freezing

Precipitation

Evaporation

السؤال 7

Solar radiation is the least important source of energy that drives the water cycle.

False

True

السؤال 8

How does gravity influence water movement within glaciers?

Gravity traps water permanently within glaciers.

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

Gravity causes glaciers to instantly melt into liquid water.

Gravity lifts glaciers to higher altitudes.

السؤال 9

What kind of climate typically characterizes regions located near the equator?

Freezing cold with heavy snow

Dry and cold

Moderately cool and dry

Warm and wet

السؤال 10

What causes water droplets and ice crystals in clouds to fall to Earth's surface?

Gravity

Wind energy

Evaporation

Solar radiation

السؤال 11

What two basic factors drive the water cycle on Earth?

Erosion and deposition

Photosynthesis and respiration

Heat energy and gravity

Wind and tides

السؤال 12

What is one critical role gravity plays in the water cycle?

It initiates the process of evaporation.

It heats the water in oceans and lakes.

It allows for the rise and fall of different densities in fluids.

It directly converts water vapor into clouds.

السؤال 13

Water vapor releases energy as it condenses into liquid water.

True

False

السؤال 14

Transpiration is the process where water vapor is released from the leaves of plants into the atmosphere.

True

False

السؤال 15

What is a primary role of oceans in the water cycle?

They serve as large reservoirs of water for the cycle.

They primarily absorb water from the atmosphere without releasing it.

They generate all the wind energy needed for water movement.

They are the sole source of heat energy for evaporation.
