[Q]: - Particles in the environment interact with rocks - The particles remove small pieces of the rock each time they touch the rocks - The particles continue to hit, brush against, or grow against the rocks - The rock eventually is broken apart by this contact - The pieces of the rock are now small rocks What might be the last step of the process?
****

input: Please answer the following: - Grass and small plants grow in an area - These plants die - The soil gains organic material - The soil becomes more fertile - Larger plants are able to be supported What might be the last step of the process?
++++++++++
output: Trees eventually grow.
Please answer this: - Sunlight passes through the glass into the greenhouse - The plants and floor absorb the the sunlight - The absorbed sunlight is converted to heat - The heat cannot escape the glass - The heat is trapped in the greenhouse - The hot air rises - The colder air at the top is pushed to the bottom What might be the last step of the process?
++++++++
Answer: The colder air is then warmed by the floor and the plants.
Problem: - Cold water taken in through a hose to the bottom - Heating element heats water - Pump forces water up in pipes connected to spinning paddles - The forced water makes paddles spin like a sprinkler - Water comes out of small holes in paddles - Water is collected and used again until dishes are clean - Water is drained through a filter - Filter collects particles of food What might be the last step of the process?

A: Water was so hot that it evaporates for dry dishes.
Problem: Given the question: - Food is taken into the mouth - The food is chewed - Saliva mixes with the food and starts breaking it down - The chewed food travels down the esophagus to the stomach - The stomach secretes acid - Grinds and mixes the food - The food moves to the small intestine - The small intestine uses enzymes to further break down the food - The food passes into the colon What might be the last step of the process?
++++++++++++++++++++++++++++++++

The food is expelled from the body.
Problem: - An animal eats a lot of food to fatten up - The animal finds or builds a suitable place to hibernate where they can stay warm and protected - The animal moves into their den - Their heart rate and breathing slow down to conserve energy What might be the last step of the process?
