What is the final step of the following process: - Dead organic material accumulates on the bottom of oceans, riverbeds or swamps, mixing with mud and sand - Over time, more sediment piles on top - The resulting heat and pressure transforms the organic layer into a dark and waxy substance known as kerogen - Left alone, the kerogen molecules eventually crack - The molecules break up into shorter and lighter molecules composed almost solely of carbon and hydrogen atoms

Answer: It will turn into either petroleum or natural gas

Q: What is the final step of the following process: - The body's temperature increases over 98.6 degrees F - The hypothalamus in the brain sends a message to the body - Sweat glands in the skin receive the message - The sweat glands start combining water and chemicals to make sweat
A: The sweat leaves the skin through pores.

Question: What is the final step of the following process: - A star burns in space - Eventually it burns all its hydrogen - Becomes a red giant - Once the red giant burns itself out - The core of the star collapses - The gasses will start to disperse - Only the core is left
Answer: A white dwarf has been formed.

[Q]: What is the final step of the following process: - Human industry produces chemical compounds - Chemical compounds rise into the air - Chemical compounds mix with elements in clouds - The affected rain falls to the earth
****
[A]: The affected rain can harm natural and man-made objects because of its acidic content.

input: Please answer the following: What is the final step of the following process: - Solution caves are formed in limestone and similar rocks by the action of water - After a rain, water seeps into cracks and pores of soil and rock - The water percolates beneath the land surface - Some of the water reaches a zone where all the cracks and pores in the rock are already filled with water - Rainwater absorbs some carbon dioxide as it passes through the atmosphere and even more as it drains through soil and decaying vegetation - The water combines chemically with the carbon dioxide - A weak carbonic acid solution is formed
++++++++++
output: This acid slowly dissolves calcite, forms solution cavities, and excavates passageways

What is the final step of the following process: - Acid rain is produced by chemicals that reach into the atmosphere - Falls onto the ground - The acid rain starts scouring rocks - Destroys vegetation
----
Answer:
The lack of vegetation alters the surrounding environment.
