Unit 3 Earth Cycles

BMMS Unit 3 Earth Cycles Review

QuestionAnswer
Carbon Cycle Components C02 Cycle Sunlight Ocean Exchange/Uptake Photosynthesis Dead Organisms Animal Respiration Fossil Fuels Factory emissions
Nitrogen Cycle Components Atmosphere Nitrogen Gas Lightning Nitric Acid Roots Nitrogen-fixing bacteria Soil Nitrogen Decomposing Consumption by Animals Consumption by Plants
Water Cycle Components Condensation Precipitation Collection/Runoff Ocean Evaporation Heat from the Sun
Oxygen Cycle Components Sunlight Animal Respiration Photosynthesis
Carbon Cycle 1 One of the most important elements on Earth. It is an element all living things are made up of.
Carbon Cycle 2 Both plants and animals need ______ in order to survive. The _____ cycle recycles ______ between inorganic and organic forms.
Nitrogen Cycle 1 This element is necessary to make proteins which are needed for many of the process and material of life.
Nitrogen Cycle 2 The ______ cycle allows this element to change forms and be utilized by organisms found on planet Earth.
Nitrogen Cycle 3 Most of this element (78%)is found on Earth is contained in the atmosphere, however, bacteria in the soil is vital in allowing nitrogen to be usable for other organisms, including plants and animals.
Water Cycle 1 This molecule is cycled amongst its three states of matter. The sun’s energy drives the different states between precipitation, evaporation, and condensation.
Water Cycle 2 This molecule is cycled through the biosphere, stopping in many different places along the way.
Oxygen Cycle 1 This element is cycled between organisms and outside of organisms throughout the biosphere.
Oxygen Cycle 2 This element main gas found in the atmosphere of Earth and can only get there with help from photosynthetic organisms.
Carbon Cycle- CO2 The biggest abiotic reservoir for carbon is found in the atmosphere in the form of CO2
Carbon Cycle- Sunlight Plants utilize sunlight and CO2 from the atmosphere
Carbon Cycle- Ocean Exchange/Uptake CO2 is absorbed in the ocean
Carbon Cycle- Photosynthesis Photosynthetic organisms use CO2, water and sunlight to make organic material
Carbon Cycle- Dead Organisms When organisms decompose, carbon is added to the soil
Carbon Cycle- Animal Respiration Animals eat plants and other animals containing carbon. Cellular respiration changes organic carbon to CO2
Carbon Cycle- Fossil Fuels Over time, carbon from decomposing organisms can be used as fossil fuels
Carbon Cycle- Factory Emissions Burning of fossil fuels releases extra CO2 into the atmosphere
Nitrogen Cycle- Atmosphere Nitrogen Gas 78% of the nitrogen found on Earth is in the atmosphere
Nitrogen Cycle- Lightning Nitric Acid Lightning is one mechanism that can change nitrogen into a usable form
Nitrogen Cycle- Roots Nitrogen-fixing bacteria Bacteria found on roots of legumes can fix nitrogen into a usable form
Nitrogen Cycle- Soil Other bacteria can convert fixed nitrogen into nitrates and nitrites for plants
Nitrogen Cycle- Nitrogen Decomposing When animals decompose, nitrogen is put back in the soil
Nitrogen Cycle- Consumption by Animals Animals eat plants that contain nitrogen
Nitrogen Cycle- Consumption by Plants Plants get usable nitrogen from bacteria in the soil
Water Cycle- Condensation Water vapor changes from gas to liquid in clouds
Water Cycle- Precipitation Once liquid water in clouds become too heavy, it falls to the Earth as rain, sleet, snow or hail
Water Cycle- Collection/Runoff Water from precipitation is collected in lakes, rivers, streams, and ground water
Water Cycle- Ocean Water on land can eventually run into one of the major oceans on Earth
Water Cycle- Evaporation Water changing form from liquid to gas
Water Cycle- Heat from Sun The sun’s energy drives the ever changing state of water
Oxygen Cycle- Sunlight The sun’s energy is used by photosynthetic organism
Oxygen Cycle- Animal Respiration Animals utilize oxygen in cellular respiration and CO2 is made in the process
Oxygen Cycle- Photosynthesis CO2 is taken out of the atmosphere in photosynthesis and oxygen gas is made in the process

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
