Ecosystems
This process, done by plants, uses sunlight to make food and releases oxygen into the air.
Photosynthesis
This force keeps you from floating away and gives objects weight
Gravity
This type of bond forms when atoms share pairs of electrons.
Covalent bond
When a liquid is changed to a solid it is called?
Freezing
What is the closest planet to the Sun?
Mercury
The process of changing to survive in an ecosystem is called?
Adaptation
This type of energy is stored in an object due to its position, such as a book on a high shelf.
potential energy
This number, found on every element’s periodic table square, tells you how many protons it has.
Atomic number
When a solid changes to a liquid it is called?
Melting
This phenomenon occurs when the Moon passes directly between the Earth and the Sun.
Solar Eclipse
This term describes the maximum population size an environment can sustainably support.
Carrying capacity
This unit is used to measure electrical current and shares its name with a famous French physicist.
Ampere
Chemical symbol for tin
Sn
This state of matter, found in stars and lightning, consists of charged particles.
Plasma
This type of star explosion can briefly outshine an entire galaxy and is classified as Type I or Type II.
Supernova
What is the term called when there is rivalry between living things for resources? Also a term in sports.
Competition
This law states that for every action, there is an equal and opposite reaction.
Newton's Third Law
This law states that matter cannot be created or destroyed in a chemical reaction.
Law of conservation of mass
This process occurs when a solid turns directly into a gas, as seen with dry ice.
Sublimation
What is another term for shooting stars? (hint: debris)
Meteor
This term describes a species that has a disproportionately large effect on its ecosystem, such as sea otters controlling sea urchin populations.
Keystone species
This phenomenon causes a straw in a glass of water to appear bent at the surface.
Refraction
This type of intermolecular force, stronger than London dispersion but weaker than ionic bonds, occurs between polar molecules
Dipole-dipole interactions
This property describes how easily a liquid flows; honey has a high one.
viscosity
This effect causes the pitch of light waves to shift depending on whether an object is moving toward or away from us (hint: red shift)
the Doppler effect
