runoff, infiltration
snow, sleet, rain, hail
we need it to live

Burning fossil fuels
by walking
We burns fossil fuels
The basic units of matter, the smallest units that maintain the chemical properties of an element, are called
atoms
lipids
compounds
molecules

solutions
elements
hydrocarbons
marcromolecules
Why is water often called "the universal solvent"?
it can dissolve many other molecules
water can turn into solid form
water is a type of solution
it solves most of the world's environmental problems

system with no feedback
positive feedback loop
negative feedback loop
destabilizing system

lithosphere
geosphere
hydrosphere
atmosphere
The lithosphere is carried on a softer, but still firm, layer of rock called the
geosphere
core
crust
asthenosphere
Which sphere are humans a part of?
geosphere
hydrosphere
biosphere
atmosphere
A change in a state in which water returns to Earth's surface and changes from a vapor to a liquid is called
condensation
transpiration
evaporation
recharge
The central core of a very atom, containing particles called protons and neutrons, is called a(n)
electron
bond
nucleus
compound
Water molecules are composed of
two oxygen atoms and two hydrogen atoms
one oxygen atom and two hydrogen atoms
two oxygen atoms and one hydrogen atom
one oxygen atom and one hydrogen atom
A process in which an event acts as both an input and output of the same system is called a(n)
feedback loop
Earth System
photsynthesis
lithosphere
Which of Earth's spheres consists of the layers of gases surrounding our planet?
geosphere
biosphere
atmosphere
hydrosphere
Water which returns from the atmosphere to Earth's surface as rain or snow is called
evaporation
transpiration
condensation
precipitation
Nutrients circulate endlessly throughout the environment in complex cycles called
eutrophication cycles
respiration cycles
photosynthesis cycles
biogeochemical cycles
Which of the following are common resources of phosphorus?
gases in the atmosphere
fertilizer and detergent
snow and rain
volcanoes
(a) are polymers that consist of atoms of carbons, hydrogen, and oxygen.
Earth's (a) consists of all the planet's living or once-living things and the nonliving parts of the environment with which they interact.
Aquifers hold (a) , fresh water found underground.
In a process called (a) , the addition of phosphorus to bodies of water can lead to an overgrowth of producers (usually algae).
Nitrogen (a) is the conversion of nitrogen gas to ammonia.
(a) are organic compounds containing only hydrogen and carbon.
The acidity or basicity of solution is described by the (a) scale.
In a (a) feedback loop, the output of a system moving in one direction acts as input that causes the system to move in the other direction.
As the asthenosphere moves, it drags along large plates of crust called (a) plates.
In (a) , producers pull carbon dioxide out of their environment and combine it with water in the presence of light.
Check off the information that explains a divergent plate boundary.
crust moves apart
magma fills in the holes
crust smashes into each other
crust gets pushed underneath more crust
Check off the information that explains a transform boundary.
plates slide passed each other
plates crash into each other
plates crush crust
