Earth's Subsystems

How is the hydrosphere distinct from the other subsystems?

• It gives food for living organisms.

• It offers shelter for land animals.

• It provides natural resources such as minerals and rocks

• It provides water for organisms which enable organisms to function properly.

The atmosphere serves as envelop which protects the earth. Which of the following is TRUE about atmosphere?

• It includes all flying organisms.

• It serves as the Earth’s blanket.

• It is affected by temperature and salinity.

• It is composed of the different landforms of the Earth.

How is biosphere different from the other subsystems?

• .It is dependent only on hydrosphere and geosphere.

• It is composed of all living organisms.

• It is composed of soil, rocks, and minerals.

• .It provides air which supports respiratory processes of living organisms.

The Agusan Marsh is a large wetland with many plants, animals, and microscopic organisms. Which part of the Earth’s subsystem includes the water in this wetland?

• Atmosphere

• Biosphere

• Geosphere

• Hydrosphere

Why are hydrosphere and geosphere involved in the given scenario below?

“Flooding moves soil and rock to new places.”

• Flood, soil, and rock are components of hydrosphere.

• Soil is part of geosphere while rock is a part of hydrosphere.

• Flood is a component of hydrosphere while soil and rock are components of geosphere.

• Flood is a part of geosphere while soil is a component of biosphere.

What is the reason why the atmosphere is essential to life?

• It only provides blanket the covers the ears the earth’s surface.

• It solely gives oxygen and carbon dioxide.

• It regulates the earth’s temperature over a period of time.

• It provides the gases essential to life and for organisms to perform bodily processes.

What subsystem interacts when a rice plant draws water and nutrients from the soil?

• Atmosphere, Biosphere and Geosphere

• Biosphere, Hydrosphere and Geosphere

• Geosphere, Atmosphere and Biosphere

• Hydrosphere, Atmosphere and Geosphere

Why are the subsystems interconnected to each other?

• They have the same composition and characteristics.

• They can alter the flow energy in a minimal amount.

• They work together to influence the climate, trigger geological processes, and affect life all over the Earth.

• They are all composed of living things that influence the flow of matter.

Oceans cover almost the entire Earth’s surface. How does it contribute to Earth’s habitable condition?

• It absorbs and redistributes solar radiation.

• It absorbs and replenishes solar radiation.

• It protects and absorbs solar radiation.

• It protects and adsorbs solar radiation.

Analyze the ecological phenomena given below. Which of the given situations shows the interaction between hydrosphere and atmosphere?

• Evaporating water

• Pouring rain

• Flowing stream

• Drinking water
