Earth and Space
$100: The theory that Earth's outer shell is divided into several plates that glide over the mantle.
Answer: What is Plate Tectonics?
This property of matter causes an object to resist any change in its motion.
Inertia
Often called the "powerhouse of the cell," this organelle generates chemical energy (ATP).
mitochondria
The negatively charged subatomic particles that spin around the outside of an atom's nucleus.
Electrons
The movement of water from Earth's surface to the atmosphere and back again.
Water cycle
This type of rock is formed by the cooling and solidification of magma or lava.
Igneous Rock
Calculated by dividing total distance by total time.
speed
The molecule that contains the genetic code unique to every individual.
DNA
Columns on the periodic table are called "groups" or "families." What are the horizontal rows called?
Periods
This instrument is used by meteorologists to measure atmospheric pressure.
barometer
The spinning of Earth on its axis, which takes 24 hours and causes day and night.
rotation
Newton’s Third Law states that for every action, there is an equal and opposite this.
reaction
This type of cell division results in four daughter cells, each with half the number of chromosomes of the parent cell (used to make gametes).
Meiosis
A substance with a pH level of 2 would be classified as a strong one of these.
Acid
The trapping of the sun's warmth in a planet's lower atmosphere due to gases like carbon dioxide and methane.
The greenhouse effect
This is the name of the supercontinent that existed about 335 million years ago before breaking apart.
Pangea
The formula used to calculate force, according to Newton's Second Law.
F= m x a
An organism that has two different alleles for a trait (e.g., Tt).
Heterozygous
This law states that matter cannot be created or destroyed in a chemical reaction.
Law of conservation of mass
This fast-flowing, narrow air current found in the atmosphere drives major weather systems across the globe.
Jet stream
The alignment of Earth, the Moon, and the Sun during a total solar eclipse.
moon between earth and sun
The final, maximum velocity reached by a falling object when the force of air resistance equals the force of gravity
Terminal Velocity
The process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
Photosynthesis
A bond formed when two atoms share electrons rather than transferring them.
Covalent bond
The phenomenon where winds blow warm water toward South America, disrupting global weather patterns and causing heavy rains or droughts.
