Waves
This is the distance measured from any point on a wave to an identical point on the next wave.
What is a wavelength?
A pulling force, attracting objects to the center of the Earth.
What is gravity?
This object orbits the sun, is not a moon and has enough mass to be round or nearly round.
What is a planet?
Remains of organisms that were once living.
What are fossils?
Physical features to help with survive.
What are behavioral adaptations?
When we see an object as green, this color is reflected.
What is the color green?
An object at rest will stay at rest and an object in motion will stay in motion unless acted on by a force.
The solar system is too big and too far apart to see all at once so this is used instead.
What is a scale model?
Layers of rock are laid down in order from oldest on bottom to youngest on top.
What is the Law of Superposition?
This type of embryos all start with gill slits and tails.
What are vertebrate embryos?
Ice and tissue paper are example of this because some light passes through them.
What are translucent objects?

What is an electromagnet.
This occurs after the full moon and most of the moon can be seen but not completely.
What is a waning gibbous moon?
The movement of weathered rock
What is Erosion?
Type of structures no longer used due to evolutionary changes in organisms.
What are vestigial structures?
This type of technology stores things as zeros and ones and the storage takes up less space.
What is digital technology?
What is the force needed to accelerate an object with a mass of 15 kg at 50m/s?
750 N
This occurs during the New moon phase when the moon completely covers the sun.
What is a solar eclipse?
At this boundary, two plates move apart causing ridges and rifts form.
What is a Divergent boundary?
