Geology
the solid layer of rock beneath the soil
bedrock
The fertility of soil is mainly dependent on the presence of this within it.
What is organic matter or decaying matter?
The matter through which a wave travels
What is a medium?
This is composed of extremely small particles, too small to be seen without a powerful microscope.
What are atoms?
This happens when the Earth is aligned between the Sun and Moon - (SEM)
What is a lunar eclipse?
These are the main layers of the Earth.
What are the inner core, outer core, mantle, & crust?
This determines how quickly water drains through soil.
What is particle size or texture?
The strength (height) of a wave.
What is amplitude?
The gravitational pull of the moon and sun along with the Earth's rotation cause these.
What are the ocean tides?
These form as two tectonic plates collide.
What are mountains?
is the green pigment inside the chloroplasts of plant cells that makes leaves green
What is Chlorophyll
This is the distance between successive peaks of a wave.
What is the wavelength?
This is a substance that is made of only one kind of atom
What is an element?
This is the main cause of the Earth's seasons.
What is the tilt of the Earth's axis?
This is the hypothesis that the continents once formed a single land mass, broke up, and drifted to their present locations
Continental Drift
When cells use a chemical reaction to change oxygen and glucose into water, carbon dioxide, & ATP
What is respiration?
Sound travels fastest through what state of matter?
What is a solid?
This describes the relationship between mass and volume.
What is density?
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?
a block of lithosphere that consists of the crust and the rigid, outermost part of the mantle.
Tectonic Plates
This is the response of a plant to external stimuli.
What is a tropism?
The interference when waves bend around an object
What is diffraction?
The temperature at which a substance turns from a solid into a liquid
What is melting point?
a space station, or a habitable artificial satellite, in low Earth orbit that serves as a microgravity and space environment research laboratory
What is the International Space Station
