Gravity
Gravity pulls water from a high __________ to a low __________
What is elevation
The process of water moving through plants..up the roots, through the stem, and out the leaves
Station 2 in Lesson 2 showed us how water moves in the forest. Did it show high infiltration or low infiltration?
What is high infiltration.
A place where water is held or collects
What is a reservoir?
These are the "veins" or "tubes" in plants.
What are xylem
When water moves across the surface, usually faster over man made surfaces.
What is run off
Water turning from a liquid to a gas
In Station 1 of Lesson 2, we poured water over bare soil. What happened to most of this water?
What is....most became runoff (very little infiltration)
Water moving through a plant.
What is transpiration
This is the boundary between soil and groundwater
What is the water table
What is it called when water soaks into soil, pulled down by gravity?
What is infiltration
In Station B of Lesson 3, explain what happened to the sponge print in the sunny spot compared to the shady spot.
What is...the water evaporated more quickly in the sun.
In Station 3 of Lesson 2 we built landform models and sprayed water over it. What happened to the water?
Acceptable answers:
What is became run off, moved from high to low elevations, collected in reservoirs.
Water moving through or being soaked in to the soil
What is infiltration
The 'mouths' on a leaf that let gasses through.
What are stomata?
Water from the clouds pulled to the surface by gravity
What is precipitation
Explain why sunlight is NOT an energy driver for groundwater
What is...water is so deep in the soil that the sun's energy can't reach
How did we know that more water moved through the celery in the light?
Acceptable answers:
Less water in the light beaker, red water in the celery, leaves stained red
The height of an object above another
What is elevation
The landform that has high elevation, but is flat on the top (not pointed like a mountain)
What is a plateau
When water infiltrates the soil, it collects in big groundwater reservoirs known as this
What is an aquifer
Name one plant process, other than transpiration, that uses sunlight as an energy driver
What is photosynthesis
Less run off occurs in the forest than over manmade surfaces like concrete and shingles. Explain.
Acceptable answers:
Forest has more things to slow the water down (leaves, sticks, grass)
Man made surfaces do not allow water to infiltrate
A place that slows or stops the flow of water
What is a system boundary
When water moves up the stem and out the leaf through transpiration, the water molecules stick to each other by this force.
What is cohesion
