The ability to cause change or do work.
What is energy?
Anything that has mass and takes up space.
What is matter?
Moving objects have this type of energy.
What is kinetic energy?
Movement of materials within Earth is caused by this source of internal energy.
What is thermal energy?
Electricity flows easily through these materials.
What are conductors?
Energy is created by fast movement particles of matter and felt as heat.
What is thermal energy?
Matter is made of these tiny particles that are too small for humans to see.
What are atoms?
Motion is described by an object's direction and the measure of how quickly an object moves.
What is speed?
Scientific theory state that these are responsible for the movement of Earth's Crust.
What are plate tectonics?
Electricity can flow only when this type of pathway is complete.
What is a closed circuit?
Energy that travels in waves and moves through empty space, like the Sun's rays reaching Earth.
What is radiant energy?
What is mass?
This force opposes motion and can slow objects down.
What is friction?
These preserved remains of ancient life provide evidence that Earth has changed over time.
What are fossils?
What is static electricity?
Energy associated with motion/position of an object, such as a moving bicycle or stretching a rubber band.
What is mechanical energy?
All of these are mixtures, but not all mixtures are these.
What are solutions?
The stored energy an object has because of its position.
What is potential energy?
This cycle explains how rocks transform from one type to another through processes such as heat, pressure, melting, and cooling.
What is the rock cycle?
Electrical energy can be transformed into these three forms.
What are radiant, mechanical, and thermal energy?
Energy produced by the movement of positive and negative charges that power devices such as lights and televisions.
What is electrical energy?
Many kinds of matter undergo this change from solid to liquid to gas when temperature increases.
What is a change in state of matter?
Changes in motion are related to these two things; the overall force and how much matter an object has.
What are net force and mass?
The three processes that reshape Earth's surface.
What are weathering, erosion, and deposition?
A current flowing through a wire creates this invisible area that can attract or repel objects.
What is a magnetic field?
