6.10A Spheres Day 2

Lisa observed a model of plants absorbing water from the soil and releasing oxygen into the air. Which of Earth’s spheres are interacting in this model, and how do they show interdependence?

• A. Biosphere and hydrosphere only because plants only require water.

• B. Biosphere, hydrosphere, and atmosphere since plants interact with water, soil, and air.

• C. Geosphere and atmosphere only, since plants contain soil and air.

• D. Biosphere and atmosphere only, since plants release carbon dioxide into the air.

A group of marine biologists are researching a coral reef. This image of a coral reef ecosystem shows the interaction of multiple Earth systems. Which two Earth systems are most prominently represented, and how do they demonstrate interdependence in this environment?

• A. Geosphere and hydrosphere; rocks provide a foundation for coral growth

• B. Biosphere and geosphere; marine life breaks down rock to form sand

• C. Atmosphere and hydrosphere; oxygen penetrates water for photosynthesis

• D. Hydrosphere and biosphere; water supports diverse marine life

Which statement is true regarding humans and our relationship with Earth’s spheres?

• A. Humans are part of the biosphere. They do not affect other spheres because spheres do not interact.

• B. Humans are part of the geosphere. They can affect the geosphere by reducing pollution through recycling.

• C. Humans are part of the biosphere. They can only affect the geosphere since that is the part of Earth where humans live.

• D. Humans are part of the biosphere. They can affect the atmosphere, geosphere, and hydrosphere by reducing pollution through recycling.

• Water droplets form on the leaves of plants.

• Insects buzzing around flowers.

• Wind blowing soil particles across the path.

• Raindrops create puddles on the ground.
