Answer: Sunlight hits chloroplasts in the plant

Problem: What is the missing first step of the following process:  -  As the saltwater is heated the water becomes a gas - The salt particles sink to the bottom of the container - Gaseous water is piped into another container - Allowed to cool - The salt particles are left behind in the first container - The second container contains fresh water.

A: The salt water is heated

++++++++++++++++++++++++++++++++
The answer is:
Water seeps into rocks

input question: What is the missing first step of the following process:  -  Magma rises - Collects inside magma chambers underneath a volcano - Pressure builds in the magma chambers as they fill - Gain energy for eruption - Some of the energy is converted into seismic activity (earthquakes) - If the magma building in the volcano is thick and sticky it will trap gases - Results in an explosive eruption when the pressure becomes too intense - If the magma is thin and runs - The magma results in a low-pressure, slow-moving flow of magma instead of a violent eruption -???
output answer: Magma is formed when rock melts inside the Earth&#x27;s crust

input question: What is the missing first step of the following process:  -  Rain falls - Water is in the area of high elevation - The water creates a stream - The stream moves towards lower elevation - The stream continues along the same path for a long time - The soil and rocks erode where the stream touches them - The stream moves deeper into the soil - The stream is smaller than the eroded area.???
output answer:
An area is at a higher elevation than the surrounding area
