Problem: - Acid rain makes waters acidic - Causes them to absorb aluminum from soil - The water runs off from the soil into lakes, streams, etc - Fish and their eggs die - Frogs and plants die - Insects and other wildlife die What might be the last step of the process?

A: The ecosystem is out of balance, causing further problems
Problem: Given the question: - A stream or river must occur - Through erosion, the stream cuts into the soil and bedrock - Through continuous erosion, a deep gash is cut through - After many years the river may dry up What might be the last step of the process?
++++++++++++++++++++++++++++++++
The answer is:
A dry ravine is left
input question: - Fault lines appear underground - The fault lines grow over time - The rocks on each side of the fault lines rub against the rocks on the other side of the fault line - The rocks put pressure on each other - The rocks break from the pressure - The breaking of the rocks releases a lot of energy - The energy causes seismic waves What might be the last step of the process????
output answer: The seismic waves make the earth shake.
- EGG - ITS LAID ON A LEAF OR PLANT - THE EGG HATCHES - THE LARVA COMES OUT(CATERPILLAR) - IT BEGINS TO EAT ON THE LEAF THAT IS WAS BORN ON - CONTINUES TO EAT TO GROW QUICKLY - AFTER ITS GROWN TO FULL LENGHT IT FORMS INTO A PUPA - UNDERGOES METAMORPHOSIS TO BECOME BUTTERFLY - AFTER HE BUTTERFLY IS FOMED IT PUMPS BLOOD INTO ITS WINGS TO GAIN STRENGHT TO BE ABLE TO FLY What might be the last step of the process?

Q: - A plant grows near or on a rock - The plant roots begin to grow - Break apart the rock - The plant acids dissolve parts of the rock - The rocks are broken into more and more pieces What might be the last step of the process?
A: Erosion starts to occur.
[Q]: - When water freezes it becomes 10% bigger, or takes up 10% more space - As water expands it puts great pressure on the walls of anything containing it, including any rocks which happen to be surrounding it - The force of the pressure exerted on the rock surrounding it is enough to wedge the walls of the crack farther apart, thus expanding and deepening the crack - Clay expends when wet like ice does - This causes rock to break apart - Some plants like mosses and lichens are capable of growing without soil on bare rock What might be the last step of the process?
****
[A]:
When they do this their roots penetrate pores and crevices and cause rocks to split apart as the roots force their way down through the rocks
