Spheres of the Earth: Web-quest What are the 4 spheres of the earth?
1. Describe each of Earth's four spheres. List several examples of
features in each sphere.
How do the 4 spheres interact?
2. For each of the following processes, list the sphere where matter
begins in the process and the sphere where matter ends in the process.
Example:
Hydrosphere Water in a lake becomes groundwater. Geosphere

-Water evaporates into the air

-Plants absorb water into their roots..

-Humans breathe in oxygen.

-Oil wells burn fossil fuels.

-Rivers deposit sediment.

step-by-step explanation:

you divide the denominator by the numerator on both sides and if the quotients are equal then the fractions are equivalent

true

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
