the type of eclipse that happens during a new moon when the moon's shadow falls on a certain area on Earth
What is a solar eclipse?
100
the main source of the gravitational pull that causes high and low tides everyday
What is the moon?
100
the 3 states of matter in order from most dense to least dense
What is solid, liquid, gas?
100
multiple paths of energy transfer in an ecosystem
What is a food web?
100
a long-term relationship between two different species that always benefits at least one of the species
What is symbiosis?
200
an attractive force between any two objects in the universe that holds planets in their orbits and gives them their spherical shapes
What is gravity?
200
the type of electromagnetic radiation that is invisible, higher in energy than visible light, and can cause sunburns
What is ultraviolet?
200
lowest particle energy, highest density, definite shape and volume
What is a solid?
200
food web role that makes their own energy and are also known as autotrophs
What is a producer?
200
type of symbiosis when both species benefit from the interaction
What is mutualism?
300
the old model of the solar system that said the Earth was the center of the solar system; this was replaced by a new model with the sun at the center
What is geocentric?
300
the type of electromagnetic radiation that is invisible but can be felt as heat
What is infrared?
300
medium particle energy and density, definite volume, can take on any shape
What is a liquid?
300
food web role that eats other organisms for energy; can be primary, secondary, or tertiary
What is a consumer?
300
type of human impact where a forest is permanently destroyed, causing a loss in biodiversity and habitat space
What is deforestation?
400
the measurement of how strongly gravity is pulling on an object; changes depending on where you are in the universe
What is weight?
400
the type of tide that happens 2 times a month during quarter moons when the moon is at a 90 degree angle from the sun and earth and there is a lower tidal range.
What is a neap tide?
400
highest particle energy and least density; no definite volume or shape
What is a gas?
400
food web role that breaks down dead organisms to recycle nutrients
What is a decomposer?
400
type of human impact caused by human population growth and the building of large cities that decrease habitat space and biodiversity
What is urbanization?
500
the hottest planet due to its thick layers of carbon dioxide, a greenhouse gas that traps heat
What is Venus?
500
type of tide that happens 2 times a month when the Earth, moon, and sun are aligned and pulling on the water surface in the same direction, causing stronger gravity
What is a spring tide?
500
the measurement of how much energy is in the particles of matter (hint: adding more of this can change the state of matter, such as turning an ice cube from a solid to a liquid.)
What is heat/temperature?
500
type of limiting factor that happens when two species try to use the same limited resource, such as eating the same type of prey
What is competition?
500
type of human impact caused from the removal of plant roots that leads to greater erosion and loss of soil and nutrients from the land
