Anything that has mass and takes up space is called ____________.
What is matter?
A puddle in the driveway evaporates after the sun pops out. What type of change is this?
What is a physical change?
The process by which small nuclei such as hydrogen are combined to form a larger element; occurs only in stars.
What is nuclear fusion?
This mechanism refers to the transportation of bits and pieces of soil and rocky material, often caused by wind, water, gravity, and glaciers.
What is erosion?
Identify the wave form depicted below:
What is transverse wave?
The electrons that are responsible for bonding; they are located furthest from the nucleus.
What are valence electrons?
This type of ion is formed when an element loses one or more electrons.
What is positive ion?
A region in space where gravity is so dense that nothing, not even light can escape.
What is a black hole?
Over the course of the winter, water enters a crack in a rock. As the temperature and pressure changes, causing the water to freeze and thaw, the rock spits in two. This is an example of ________.
What is physical weathering?
A wave that requires a medium to travel; they cannot travel in space/ a vacuum. Sound is an example of this type of wave.
What is a mechanical wave?
A compound that contains both carbon and hydrogen atoms. It may also contain other types of atoms, and it is associated with both living and nonliving things.
What is an organic compound?
These elements tend to lose electrons to form positive ions. As a result, they are good conductors of both heat and electricity.
What is a metal?
Suppose the force of gravity between our sun and the planets was suddenly turned off. What would happen to the planets in the absence of any gravitational force?
What is fly off into space a straight line?
What three items are needed for a sand dune to form?
What are wind, loose material, and an obstacle?

What type of formation is depicted in the image below where the Yukon river meets the sea?
What is a delta?
The portion of the electromagnetic spectrum used for cell phone communication, Wi-Fi, and even Doppler radar.
