Unit 4 Study Cards

Water Cycle, Weather/Climate, Life Sciences

TermDefinition
Weather The changes that occur(happen) day to day.
Climate The weather of a place over a very long period of time.
Ecosystem A setting(Place) that has living(Biotic) and Nonliving(Abiotic) that interact with each other.
Water Cycle How water goes from the surface to the atmosphere and back to the surface.
Precipitation Rain, Sleet, Hail, or Snow. When condensation gets too heavy and falls to the Earth in the form of one of these.
Condensation When water that has evaporated builds up(gathers) in the atmosphere in the form of clouds.
Accumulation when water that has runoff or fallen back down through the earth(precipitation) gathers in a certain spot. Where the water cycle begins again.
Evaporation When water gets too hot and turns into water vapor. Rises to the atmosphere where it forms clouds.
Rotation 24 Hours. the Earth rotates once a day. This causes Day and Night
Day/Night During the day we are facing the Sun. At night time we are facing the other way. 12 PM-Directly facing the sun. 12 AM- Facing the opposite way from the sun( why there is no sunlight on our side of the Earth).
Earth and Sun Since the Earth rotates the sun appears to move. It is actually the earth moving East to West. This is why we get shadows.
Moon Cycle It takes the Moon about 28-30 days to go around the Earth. About every two weeks there is a New Moon or a Full Moon. Steps- New Moon, First Quarter, Full Moon, Third(Last) Quarter, New Moon. It repeats.
Non-living Element Soil, Water, Air, Rocks, Pebbles. Anything that is not alive!!!
Organism(Living) Something that is alive. Mouse, Lizard, Human, Giraffe, Starfish, Plants, Flowers, Trees. If it breathes, makes energy, or eats energy it is a living Organism.
Food Chain A sequence that shows the transfer of energy.
Transfer of energy When an organism eats another organism to gain energy(Keep on living).
Producer Makes energy through Photosynthesis(USing light to make energy).
Consumer An organism that eats a producer. May be an omnivore or a herbivore
Secondary Consumer An organism that eats consumers that eat producers. Example-
Predator Hunts other organisms to get energy. As a food source.
Decomposer An organism that eats another organism that is no longer alive. Worms are a great example.
Increase When an organism is not being consumed as much or there are more resources(Food,water,grass). There will be a population increase.
Decrease When there is a shortage of water, food, or a habitat. Also, when an organism is being consumed more. There are less of an organism.
Oxygen What plants and trees release that humans need in order to breathe.
Carbon Dioxide What humans and animals release that plants and trees need to survive.
Interdependent When two or more organisms need each other to survive.
