Ch.3 The Biosphere Test

Front

What is a wetland?

Back

A wetland is an ecosystem that is saturated with water, either permanently or seasonally, and supports aquatic plants.

Front

Where do phytoplankton primarily live in the ocean?

Back

Phytoplankton primarily live within about 200 meters of the ocean surface, where they can access sunlight for photosynthesis.

Front

What role do greenhouse gases play in Earth's atmosphere?

Back

Greenhouse gases trap heat that is radiated from the Earth's surface, contributing to the greenhouse effect.

Front

How do greenhouse gases interact with sunlight?

Back

Greenhouse gases absorb heat, and sunlight is the source of energy that generates this heat.

Front

What is the greenhouse effect?

Back

The greenhouse effect is the warming of Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

Front

What are primary producers in ocean food chains?

Back

Primary producers in ocean food chains are organisms like phytoplankton that convert sunlight into energy through photosynthesis.

Front

What is the significance of the 200-meter depth in the ocean for phytoplankton?

Back

The 200-meter depth is significant because it is where enough light penetrates for phytoplankton to perform photosynthesis.

Front

What are some examples of greenhouse gases?

Back

Examples of greenhouse gases include carbon dioxide (CO2) and methane (CH4).

Front

What happens to sunlight when it reaches the Earth's surface?

Back

Sunlight is absorbed by the Earth's surface, warming it, and some of this heat is then radiated back into the atmosphere.

Front

What is the relationship between severe weather events and climate change?

Back

An increase in severe weather events, such as hurricanes and tornadoes, can be indicative of changes in the Earth's climate system.
