Answer:
Groundwater flows from areas with a higher water table surface to areas with a lower water table. This mixture of carbonic acid in water makes most natural surface waters slightly acidic. As slightly acidic water infiltrates the ground to become part of the groundwater system it causes weathering of the rocks.

Explanation:
I got this from answers.com and this is a way to say thank you for helping me make a 90 on my math test and good luck.
Is that objects ( living or nonliving) contain spirits
Eₖ = √1/2 mv²
Eₖ/v² = 1/2 m
2Eₖ/v² = m
mgh = 1/2 mv²
gh = 1/2 v²
2gh = v²
v = √2gh
= √2 × 10 N/kg × 2 m
= 6.324 ms⁻¹
m = 9.8/(6424)²
= 9.8/39.993
= 0.245 g
I am not sure if it's correct.
i transposed for m in the first equation then to find the velocity I combined the potential and kinetic energy equation. there was no mass because velocity doesn't depend on the mass
Then I used earth's gravitational field strength (g) 10 N/kg and the 2 m was the height provided in the question
you can try working and see if you get the same
Answer:
Each layer in the Earth's crust changes in fundamental ways the closer it is to the planet's core. There are four layers of the Earth, and each layer has a different density, composition, and thickness. Three hundred years ago, English scientist Isaac Newton created the foundation for current scientific thought about the density of the Earth’s layers.
