Evaporation

What step of the water cycle is represented by the part of the diagram circled in red where water is being filtered as it passes through the soil? (precipitation, evaporation, transpiration, runoff, condensation, infiltration)

The rain, snow, sleet, and hail in the picture above best represents what step of the water cycle?

CLOUDS best represent which step of the water cycle?

What step of the water cycle is represented by the part of the diagram circled in red showing water moving from the surface to a body of water?
(percipitaion, evaporation, transpiration, runoff, condensation)

Mr. Beeler asked the class to explain what infiltration is. Below are 3 students answer:

Maria: Infiltration is when plants lose water from their leaves
Joselyn: Infiltration is when water soaks into the soil
Sam: Infiltration is when water on the surface of the runs into a body of water like a lake
Which student do you agree with?

None of the students

Joselyn

Maria

Sam

What is infiltration?

Percolation (filtering through) of water from above ground to underground

Gravity causes water to fall from the sky

Solar radiation heating up liquid water and creating water vapor

Loss of water through their leaves

How do humans alter the water cycle?

Overuse it - use it faster than it can replenish itself

Draining and filling wetlands for farming or urban development increases the risk of flooding

Hard paved surfaces prevent recharing of groundwater reduces infiltration

Reduced shade causes more evaporation before it can infiltrate soil

Accelerate topsoil erosion

Increasing the power of sunlight through mirrors causes increased precipitation

Increase pollutants in runoff

Alter weather - deforestation reduces transpiration

Carbon Cycle

null

Most of the earth's carbon is found where?

In Water

In the Atmosphere

In fossils

Which is TRUE about photosynthesis

It is done by animals/consumers

It releases carbon dioxide into the atmosphere

It is when plants use carbon dioxide to make sugar

It happens when something is burned

How do consumers get the carbon they need?

By eating plants and animals

By breathing in carbon dioxide

By performing photosynthesis

By drinking water

When a person breaths out CO₂ what process is involved?

Photosyntheis

Combustion

Decomposition

When a tree dies bacteria and fungi break it down. What is this process called?

Decomposition/Decay

Atmosphereic Carbon

Photosynthesis

Jonathan is talking about the process when carbon dioxide is absorbed into the ocean. What is the name of this process?

Combustion

Photosynthesis

Decay

Ocean Exchange

A forest fire is an example of:

Respiration

Combustion

Photosynthesis

Decomposition

How do humans alter the carbon cycle?

Increased concetration of carbon dioxide and other greenhouse gases (methane, water) are warming our planet and projected to charge Earth's climate

Clear cutting of carbon-absorbing vegetation (especially tropical rain forests) have released large amounts of carbon to the atmpsheore

Planting millions of trees increases the amount of carbon dioxide into the atmosphere because of the increased photosynthesis

Extraction and burning of fossil fuels that have taken millions of years to form have released large amounts of carbon dioxide into the atmosphere

Nitrogen Cycle

70%

78%

90%

What is assimilation?

Special bacteria found in the roots of plants to change nitrogen gas into a useable form

The process of plants and animals taken in nitrogen

Living things

The loss or removal of nitrogen or nitrogen compounds specifically

What happens to the nitrogen found in the remains of dead organisms?

It flies away

It turns into an animal

It is returned to the soil

What is assimilation?

Special bacteria found in the roots of plants to change nitrogen gas into a useable form

The process of plants and animals taken in nitrogen

Living things

The loss or removal of nitrogen or nitrogen compounds specifically

What is the major reservior of nitrogen?

Atmosphere

Soil

Oceans

Plants and animals

How does nitrogen get to the soil?

Rocks

Bacteria

Snow

Process by which ammonium is changed into nitrates by bacteria.

Fixation

Nitrification

Denitrification

Assimilation

Process when the plants absorb nitrates from the soil into their roots.

Fixation

Nitrification

Denitrification

Assimilation

Process when extra nitrogen in the soil is put back out into the air.

Fixation

Nitrification

Denitrification

Assimilation

Ammonification is part of the decaying process. When a plant or animal dies, decomposers like fungi and ________turn the nitrogen back in ammonium so it can reenter the nitrogen cycle.

Rock

Oxygen

Animal

Bacteria

Denitrification is performed by

Rock

Oxygen

Animal

Bacteria

How do humans alter the nitrogen cycle?

Harvesting of crops, irrigation, and burning or clearing of grasslands and forests can cause nitrogen to wash way from topsoil

Planting corn advances photosynthesis which absorbs nitrogen from the atmosphere

Agricultural runoff of fertilizers, animal manure, and sewage discharge add excess nitrates (NO₃^-) to bodies of water which can lead to eutrophication

Adding NO_X to the atmospehre as we burn fossil fuels

Deforestation releases large quantities of nitrogen stored in soils and plants back to a gas

Anaerobic bacteria break down inorganic fertilizer or manure and contribute N₂O to the atmosphere

Phosphorus Cycle

null

What is the major reservoir of the phosphorus cycle?

Atmosphere

Ocean

Rocks and soil

Plants and animals

Why is Phosphorus an important molecule for life?

It makes up the cells

It makes up chloroplasts

It makes up DNA & ATP

It makes up the digestive system

How do animals receive phosphorus?

They consume it from plants or animals

They absorb it from water

They breathe it in

They absorb it from soil

How do plants receive phosphorus? (More than one choice)

They consume it from plants or animals

They absorb it from water

They absorb it from air

They absorb it from soil

What happens to Phosphorus that erodes from rock and soil?

The phosphorus becomes a part of the atmosphere

The phosphorus becomes a part of the animals

The phosphorus becomes a part of the plants

It mixes with oxygen to form phosphate and is a part of the water

What happens to the phosphates when plants and animals die?

It decomposes and returns to the soil or water

It vaporizes and returns to the atmosphere

It solidifies and becomes rock

What happens to the phosphorus that is carried by runoff to the oceans?

It is evaporated into the atmosphere

It settles to the bottom of the ocean as marine sediment

What is different about the Phosphorus cycle when compared to the water and carbon cycles?

There is no atmospheric component

There is no plant component

There is no animal component

There is no water component

Similar to the nitrogen cycle, excess phosphorus in water ecosystems can cause

Acid rain

Nitrogen fixation

Eutrophication (algal bloom) dead zones

Denitrification

How do humans alter the phosphorus cycle?

Phosphates accumulation as a gas and fall down to Earth in the form of precipiation

Runoff of soaps and detergents can lead to eutrophication in bodies of water

Clear cutting rain forests can cause phosphates to wash away

Mining phosphate salts which are added to fertilizers to add to agricultural fields can runoff and cause eutrophication
