Geographical Systems and Water Cycle

The main characteristic of an open system is:

• It exchanges energy and matter with its surroundings.

• It does not exchange energy and matter with its surroundings.

• It only exchanges energy with its surroundings.

• It only exchanges matter with its surroundings.

Dynamic equilibrium in a system is:

• a state where the system is static and unchanging

• a state where the system is in constant motion without any balance

• a state where the system's forward and reverse processes occur at the same rate

• a state where the system is in chaos and unpredictable

What is an example of positive feedback in the environment?

• Melting of polar ice reduces the Earth's albedo, leading to more heat absorption and further ice melt.

• Trees absorbing carbon dioxide and releasing oxygen.

• Animals migrating to warmer climates during winter.

• Plants growing towards sunlight.

Which of the following is NOT a major global water store?

• Oceans

• Ice caps and glaciers

• Rivers

• Groundwater

What percentage of Earth's water is stored in the oceans?

• About 71%

• About 97%

• About 50%

• About 85%

The primary source of water vapor in the atmosphere is

• oceans

• rivers

• lakes

• glaciers

Which process contributes the least to atmospheric water vapor?

• Evaporation from oceans

• Transpiration from plants

• Sublimation from ice

• Condensation in clouds

Which freshwater source contains the largest proportion of Earth's surface freshwater?

• Lakes

• Rivers

• Glaciers and ice caps

• Groundwater

Which factor has the greatest influence on the rate of evaporation?

• Temperature

• Humidity

• Wind speed

• Surface area

Water vapor condenses as it rises into the atmosphere because:

• it cools and loses energy.

• it heats up and gains energy.

• it remains at a constant temperature.

• it absorbs more sunlight.
