Miller and Levine Chapter 4 Review

Front

What is evaporation in the water cycle?

Back

Evaporation is the process by which water changes from a liquid to a gas (water vapor) and enters the atmosphere, primarily from oceans, lakes, and rivers.

Front

What role does transpiration play in the water cycle?

Back

Transpiration is the process by which water is absorbed by plant roots, moves through plants, and is released as water vapor through pores in leaves, contributing to the water cycle.

Front

Define runoff in the context of the water cycle.

Back

Runoff is the flow of water, usually from precipitation, that moves across the ground and returns to bodies of water, such as rivers, lakes, and oceans.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Front

Explain the process of nitrogen fixation.

Back

Nitrogen fixation is the conversion of atmospheric nitrogen (N2) into a form that plants can use, typically ammonia (NH3), facilitated by certain bacteria in the soil.

Front

What is the significance of the carbon cycle?

Back

The carbon cycle is crucial for regulating Earth's climate and supporting life by recycling carbon among the atmosphere, oceans, soil, and living organisms.

Front

Describe the role of cellular respiration in the carbon cycle.

Back

Cellular respiration is the process by which organisms convert glucose and oxygen into energy, carbon dioxide, and water, releasing carbon back into the atmosphere.

Front

What is the hydrosphere?

Back

The hydrosphere encompasses all water on Earth, including oceans, rivers, lakes, glaciers, and groundwater.

Front

Define the term biosphere.

Back

The biosphere is the global sum of all ecosystems, where life exists, including land, water, and the atmosphere.

Front

What is the geosphere?

Back

The geosphere refers to the solid parts of Earth, including rocks, soil, and the landforms that make up the planet's surface.
