Capillarity Homework

Why does water move from the roots to the leaves of plants through the plants' tiny tubes?

• specific heat 
• capillary action

• atoms

• density

What is it called when rainwater contributes to the flow of rivers and streams?

• Transformation
• Runoff
• Irrigation
• Desertification

___________________ is the movement of water into the ground due to the pull of gravity.

• runoff
• infiltration
• evaporation
• precipitation

Having pores or openings that permit liquids or gases to pass through is called

• Absorption

• Permeable

• Impervious

• Saturation

Runoff water that is absorbed by subsurface of soil and rock.

• Groundwater

• Infiltration

• Wetland

• Saturation

The name of the area that is the upper level of the zone of saturation:

• Zone of Saturation
• Zone of Aeration
• Water Table

Groundwater is found in permeable rocks. Permeable means…

• porous

• nothing can pass throughc

• caves and caverns

• answer not shown

As permeability increases

• Infiltration decreases and runoff decreases

• Infiltration increases and runoff decreases

• Infiltration decreases and runoff increases

• Infiltration increases and runoff increases

A major cause of floods is

• light rain over a large area.
• increased capacity of stream channels.
• empty space in the zone of saturation.
• no space in the zone of saturation

Water flowing downslope along Earth's surface is called ___.

• water fall

• runoff

• water shed

• stream
