Astronomy
Subatomic particles with a negative charge. Found in shells around the nucleus of an atom.
What is an electron
Outermost layer of the Earth. Made of oceanic and continental tectonic plates.
What is the lithosphere?
Large storage of groundwater.
What is an aquifer?
78% of the atmosphere is composed of this gas.
Nitrogen (n2)
All the interacting populations of different species that live in the same geographical area at the same time.
What is a community?
Massive interstellar cloud of dust; birthplace of stars
What is a nebula?
The process of molten material from the mantle being pushed upward to the surface of the Earth and spreading apart.
What is sea floor spreading?
A process that changes the chemical makeup of the ocean to make it more acidic; bleaches coral reefs
What is ocean acidification?
Atmospheric conditions in a region over a SHORT period of time. (rain, humid, windy.)
What is weather?
Trophic level that eats primary consumers.
What are secondary consumers?
The fusing of hydrogen atoms in the core of the sun
What is nuclear fusion?
Process where one lithospheric plate collides and plunges down into the mantle.
What is subduction?
land area where a river meets a larger body of water; created by the deposition of the sediments that are carried by the waters of a river. (Mississippi River ______________.)
What is a delta?
Gases in the atmosphere released by the burning of fossil fuels that retain heat.
What are greenhouse gases?
A species on which other species in an ecosystem largely depend, such that if they were removed the ecosystem would change drastically.
What is a keystone species?
This layer of the sun acts as a passageway for the energy that is released from the core.
What is the radiative zone?
Type of rock that is formed through heat and pressure.
What is metamorphic rock?
the subsurface layer of soil and rock where all interconnected pores, cracks, and spaces are completely filled with water. (groundwater)
What is the zone of saturation?
Currently the most utilized form of alternative energy, but the building of dams for this energy destroys animal habitats.
What is hydroelectric power?
Yorkies, Beagles, and Huskies are an example of this type of biodiversity.
What is diversity of genes?
Produced by radioactive elements. Can not be seen or felt.
What are gamma rays?
Two dimensional representation of a three dimensional landform.
What is a topographic map?
The ability of a liquid to flow through narrow spaces against gravity; due to the cohesive and adhesive properties of water
What is capillary action?
Chemicals that were widely used in refrigeration, air conditioning, and aerosols that interact and deplete stratospheric ozone.
What are chlorofluorocarbons?
The Mesozoic Era consists of these three periods.
What is the Triassic, Jurassic, and Cretaceous periods?
