Problem: 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.

A: An area is at a higher elevation than the surrounding area

Problem: Given the question: What is the missing first step of the following process: - The light energy is used to convert carbon dioxide - The plant uses nutrients in the soil - The plant uses carbon dioxide in the air to produce glucose - The plant uses the glucose to give itself energy - Oxygen is released as a by product.
++++++++++++++++++++++++++++++++
The answer is:
Light energy is absorbed by chlorophyll in a plant

input question: What is the missing first step of the following process: - The movement is due to a combination of gravity acting on the sediment, and/or the movement of the fluid in which the sediment is entrained - Sediment transport occurs in natural systems where the particles are clastic rocks (sand, gravel, boulders, etc.), mud, or clay - The fluid is air, water, or ice - And the force of gravity acts to move the particles along the sloping surface on which they are resting - Sediment transport due to fluid motion occurs in rivers, oceans, lakes, seas, and other bodies of water due to currents and tides - Transport is also caused by glaciers as they flow -???
output answer: Sediment transport is the movement of solid particles (sediment)
