Question: What is the missing first step of the following process: - 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 - The colder air is then warmed by the floor and the plants.
Answer: Sunlight passes through the glass into the greenhouse

[Q]: What is the missing first step of the following process: - 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 - This acid slowly dissolves calcite, forms solution cavities, and excavates passageways -
****
[A]: Solution caves are formed in limestone and similar rocks by the action of water

input: Please answer the following: What is the missing first step of the following process: - The top layer are 'doped' with impurities to allow a negative charge - The bottom layer are 'doped' to allow for a positive charge - This produces an electric field that allows electrons to flow from negative to positve - Sunlight enters the cell - Energy from sunlight knocks electrons loose in both fields - This prevents the flow of electrons from negative to positive - Adding an external circuit allows the exchange to continue - Give the cells owner a flow of electricity.
++++++++++
output: A photovoltaic cell is created with two layers of semiconductor material

Please answer this: What is the missing first step of the following process: - 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 - The seismic waves make the earth shake.
++++++++
Answer: Fault lines appear underground

Problem: What is the missing first step of the following process: - The sediment breaks down into small particles - Wind or water picks up the sediment - The sediment travels along the same route as the wind or water - The sediment is deposited at new locations by the wind or water - The sediment is picked up again by new wind or water - The sediment travels further - The sediment is deposited again in a new place.

A: Sediment settles in a place due to gravity

input: Please answer the following: What is the missing first step of the following process: - The oxygen travels into the body - Breaks down into glucose - Carbon dioxide is produced by the glucose breakdown - The carbon dioxide is exhaled out of the body through the nose or mouth.
++++++++++
output:
A person takes in oxygen through their nose or mouth
