These are vibrations in the earth that release the (potential) energy stored in rocks.
What are earthquakes?
100
The fertility of soil is mainly dependent on the presence of this within it.
What is organic matter or decaying matter?
100
All waves transmit _______________ not matter.
What is energy?
100
This is composed of extremely small particles, too small to be seen without a powerful microscope.
What are atoms?
100
The number of hours of daylight and the intensity of the sunlight both vary in a predictable pattern that depends on a location's ____________.
What is latitude?
200
These are the three main layers of the Earth.
What are the core, mantle & crust?
200
This determines how quickly water drains through soil.
What is particle size or texture?
200
The strength (height) of a wave.
What is amplitude?
200
All matter has mass and this property.
What is volume (takes up space)?
200
The gravitational pull of the moon and sun along with the Earth's rotation cause these.
What are the ocean tides?
300
These form as two tectonic plates collide.
What are mountains?
300
Fruit is formed on a plant after a flower appears and this happens.
What is fertilization?
300
This is the distance between successive peaks of a wave.
What is the wavelength?
300
Temperature and pressure determine this property of matter.
What is its state (solid, liquid, or gas)?
300
This is the main cause of the Earth's seasons.
What is the tilt of the Earth's axis?
400
The Earth's rock is constantly recycled with new land being created at this type of boundary.
What is divergent?
400
This is the process of combining oxygen with sugar to release its energy.
What is respiration?
400
This is the only type of wave that can travel through a vacuum (ie., space).
What is light?
400
This describes the relationship between mass and volume.
What is density?
400
The Solar System consists of the Sun, planets, moons, dust, gases and primarily empty space along with these three types of icy/rocky objects.
What are asteroids, meteors, and comets?
500
Earthquakes tend to coincide with this type of geologic event.
What are volcanic eruptions?
500
This is the response of a plant to external stimuli.
What is a tropism?
500
The names for the top and bottom of a wave.
What are the crest and trough?
500
This is the transfer of heat energy through a liquid (air, water, etc).
What is convection?
500
Mankind's exploration of space has led to the development of many telescopes looking for an Earth-like planet. We plan to inhabit this planet within the next 10 years.
