Heat Transfer - Quizlet
Conduction: the transfer of thermal energy between things that are touching
Ex: On a beach on a summer day – your feet feel hot from the sand. Over time the heat from the sand will transfer to your cooler feet, until both the sand and your feet are the same temperature.
Ex: Heating a pot of water on an electric stove. Heat moves from the hot surface to the metal of the pot. The heat travels to the water on the bottom. As the bottom of the pot gets hot, heat also moves to the middle and then the top and out to the handle.
Conductor: a material through which heat can move easily
Ex: iron, silver, copper, aluminum, stainless steel
Insulator: a material that heat does not move through easily
Ex: plastic, wood, rubber, glass
Convection: the transfer of thermal energy by movement of liquids or gases
Ex: Pot on the stove
- Remember that the water at the bottom of the pot is heated by the metal pot that it is touching. This is conduction.
- Convection currents transfer heat throughout the water. Convection currents form because warm water is lighter than cooler water (same is true for air, as we previously learned in the weather unit). So cool water sinks, gets warmed, and then rises. This is a constant cycle.
- Convection currents also warm air in a room. Warm air rises, cools, and then sinks. The cycle continues.
- Convection currents also move heat through Earth’s oceans and atmosphere.
Radiation: the transfer of energy by electromagnetic waves
- transfers heat through matter and empty space
- the sun is Earth’s main source of electromagnetic waves
- this energy drives the water cycle
Ex: crumbling up a piece of paper, slicing an orange, mixing flour and sugar
Chemical Change: a change in which one or more new types of matter form. Materials react with each other, or combine in new ways to form other materials.
Ex: rust forming on metal, veggies changing color when rotting, a gas given off when two materials combine.

Water Cycle - QuizletWater Cycle: the movement of water between Earth’s surface and atmosphere
atmosphere: the mixture of gases and dust that surrounds Earth
energy: the ability to make things move or change
evaporation: the change from a liquid to water vapor (gas)
transpiration: the process of plants giving off water through stomata in leaves; water evaporating from plant leaves
condensation: the change from water vapor to a liquid
precipitation: water that falls from a cloud in the atmosphere in the form of rain, snow, hail, or sleet
runoff: excess water that the ground cannot absorb; flows over the land surfaces into bodies of water.
collection: when precipitation accumulates in a body of water, in the ground, or as runoff to a body of water
Ecosystems - QuizletEcosystem: all living and non-living things in an environment
Biotic: living parts
Ex: human, animals, tree, bacteria
Abiotic: non-living parts
Ex: cloud, rocks, minerals, air, sun
Producer: organism that produces its own food, using energy from the sun (photosynthesis)
Ex: plants, algae
Photosynthesis: the process by which plants, algae, and some bacteria use energy from sunlight to make their own food
Consumer: organism that relies on other organisms for food
Ex: fox, wolf, human
Decomposer: organism that gets energy by breaking down nutrients in dead organisms
- “recyclers” because they return nutrients to soil
- Ex: earthworms
Herbivore: an animal that eats only plants
Ex: deer, rabbit
Carnivore: an animal that eats only other animals
Ex: lion, hawk
Omnivore: eats both plants and animals
Ex: me!, bear
Population: a group of organisms of the same species living in the same place
Ex: the number of deer that live in Willow Spring, NC
Community: made up of all the populations that live in the same area
Ex: the number of animals (the population of deer, fox, dogs, cats, etc) that live in Willow Spring, NC
Habitat: the physical space used by a population = home
- Includes living and nonliving parts
- Includes habitat, climate he lives in, when & what they eat
Predator: organism that eats other organisms in order to live
Prey: organism that is eaten / hunted
Limiting Factors: nonliving (abiotic) resources (light, water, soil) that limit the # of organisms living in an ecosystem
Food Chain: shows path of energy as it flows from one organism to another
Ex: grass ---> mouse ---> snake ---> hawk
Food Web: diagram of several connected food chains
- Arrow follows the path of energy SO the arrow points towards the eater
