Question: What happens after the rain falls down to earth?
You selected this answer: c) Plants absorb the water into their roots.
Some rainwater soaks into the ground. Soil is permeable, which means that water can
flow through it. There are tiny pores, or empty spaces, between the particles of sand,
gravel, and clay that make up soil. Toward the surface of the ground, these pores
contain both air and water. This is where plant roots will grow because plants need
both water and air to survive. Rainwater that soaks into this upper zone of the soil may
find itself sucked into the roots of a plant. Later that water will be released back into
the air through the plant’s leaves in a process called evapotranspiration.
Water that is not used by plants may continue to soak down through the soil until it
reaches the zone of saturation. This is where water completely fills all the pore spaces
between the soil particles and fractured rock underground. Water in this zone is called
groundwater. Groundwater doesn’t just sit there. It keeps moving through the soil, and
eventually discharges into the nearest lake, river, or stream where the water continues
its movement through the water cycle.
HOWEVER, there is another
multiple choice answer that is
even better than this one
so please TRY AGAIN!
