Space Science
What is brightness?
A H-R Diagram is a graph that plots temperature and this.
Mass divided by volume.
What are organisms?
Atoms to molecules to cells to tissues to organs to organ system.
What is erosion?
Deforestation can cause this effect on the Earth surface.
What is an independent variable?
This is the one variable that you can change in an experiment.
What is a solar system?
This is smaller than a galaxy but larger than a star.
What is refraction?
This is the bending waves as they pass through a different medium.
What is contained in a plant cell?
cell walls and chloroplasts
What is an earthquake?
This can occur with the movement of tectonic plates along fault lines.
What is the dependent variable?

What is Earth - moon - sun?
This is the alignment of the Earth, Sun, and moon during a solar eclipse.
What is potential?
What is an example of parasitism?
A tick living on a dog.
What is the lithosphere?
This is the solid outer part of the Earth, and includes the crust.
What is repetition?
This is when a scientist repeats his own experiment.
What are tides?
This is caused by the moon's gravitational pull.
What is weight and mass?
One is a measure of the force of gravity, the other is a measure of matter.
What is heredity?
The passage of genetic instructions from one generation to another.
What is the cryosphere?
This is the sphere of the Earth which contains glaciers.
What is replication?
This is when one scientist performs the experiment of another scientist.
what are gravity and inertia?
gravity is the force that attracts a body toward the center of the earth, or toward any other physical body having mass.
Inertia is a tendency to do nothing or to remain unchanged.
What is a physical change?
Water boiling is an example of this kind of change.
What is extinction?
Failure of a species to adapt to a changing environment.
What is climate?
Unlike weather, which can change daily, this is the average pattern of atmospheric conditions such as temperature.
This is not a controlled experimenter, but is used when scientist study organism in their natural surroundings.
