5th Grade

Land form that has a V-shape between two hills or mountains and is created by running water

Coal, oil, natural gas are resources that took millions of years from remains of organic matter

Form of alternative energy uses force of moving water to turn a turbine to produce electricity

The amount of space that an object takes up

To hold or absorb water, clay soil hold more water than humus

A material that can allow heat or electricity trough it such as copper and aluminium

The form of energy that comes from the movement of an object

Movement of a planet around the sun. It takes Earth one year to travel around the sun

The ability to do work, such lifting or moving an object.

A state of matter that has also no shape and takes the shape of its container

Anything that has mass and takes up space

The temperature at which a solid such as water begins to melt

Mixture of broken-down nonliving things and once-living things

The form of energy that is produced from vibrating objects

A huge sheet of slowly moving ice that can create a U-shape valley, deposits ice to form lakes

A deep valley carved by a long-time process of weathering and erosion by a moving river

Seems to change shape as it revolves around the Earth, it takes 28-29 days to cycle

The metric unit of measure when finding the mass of an object using a triple beam balance

Light waves bend when they leave one material and enter another, matter looks closer

Fossil

A substance that dissolves into another and becomes a special mixture

Fossil fuel created by build-up of plant & animal remains built over-time in marshes and wamps

Form of energy such wind, geothermal, hydroelectric, biofuel and solar energy, does not run out

Carrying away of sand & sediment from one place to another by moving water, ice and wind,

From of alternative energy that uses moving air to turn a turbine to produce energy

Energy created by using stored energy in organic or product of a living organism such plants

Breaking down of rock exposed to wind, ice, water, breaking rocks in small pieces

The form of energy that is produced when electrons move from one place to another (circuit)

A state in matter that keeps its shape and has mass. The particles are tightly packed

Living and once living organism material found in soil

The temperature at which water freezes

The temperature at which water boils

Alternative energy that takes heat from melted rocks deep below Earth, used to heat buildings

an object that pulls another object made from iron and steel toward it

A path for a constant flow of electricity. Electrical energy flows through this

Two or more substances that are mixed and can be separated

The dropping of sediment in a new location

The bouncing back of light rays from a smooth surface such as a mirror

Describes matter, appearance, texture, color, shape, size, odor, melting, boiling point, mass

Materials that come from Earth necessary for life, such rocks, water, air, sun

A state of matter that flows, has no shape, takes the shape of its container and takes up space

Solid fossil fuel created by build-up of plant remains, layer upon each other over a long time

Force that pulls objects towards each other. the Earth has more of this than the moon

Rotate

the degree of heat or cold in Celsius

The form of energy of moving particles that produces heat

A material that does not allow heat or electricity to flow through it such as rubber

Type of rock formed when layers of sediments were pressed & cemented together over a long time

The form of energy that comes from a light source

Liquid fossil fuel used as a source of energy for homes and vehicles

A force between two things rubbing against each other and works against motion slowing things

Rise/fall of water level in ocean, two high & two low daily, gravitational pull from the moon

The amount of matter in an object

Form or alternative energy that comes from sunlight

The amount of gravity pulling on an object

Resources that cannot be replaced as fast as they are used in our lifetime, such fossil fuels

Resources that nature produces over again and again such trees, plants, animals
