Aquatic Science: Water's Physical Properties, Importance, and Pollution Effects Study Guide | Quizlet

Evaporation

What process in the water cycle involves liquid water turning into water vapor due to heat?

Condensation

What process in the water cycle involves water vapor cooling to form clouds?

Precipitation

What process in the water cycle represents water falling from clouds back to Earth's surface?

What is surface runoff in the water cycle?

Water flowing over the land surface into rivers, lakes, and streams rather than soaking into the soil.

What is infiltration in the water cycle?

The process by which water on the ground surface enters into the soil.

What component of the water cycle stores underground water in permeable rock or soil layers?

Groundwater (aquifer)

What three specific bodies of water are listed as surface water in the water cycle diagram?

River, lake, and stream

Which atom in a water molecule holds a partial negative charge?

Oxygen ($\text{O}$)

Which atoms in a water molecule hold partial positive charges?

The two hydrogen atoms ($\text{H}$)

What is the electronegativity value for oxygen shown in the water molecular model?

$$3.44$$

What is the electronegativity value for hydrogen shown in the water molecular model?

$$2.20$$

Why is a water molecule classified as polar?

Oxygen has a higher electronegativity ($3.44$) than hydrogen ($2.20$), pulling shared electrons closer to oxygen and creating partial positive and negative poles.

What physical property of water enables an insect like a water strider to walk on its surface?

Surface tension

What agricultural application of water is shown in the field diagram?

Sprinkler irrigation for watering crops

What is the average annual rainfall for the far western region of Texas around El Paso?

$$10\,\text{inches per year}$$

What is the maximum average annual rainfall value shown in far eastern Texas near Beaumont?

$$55\,\text{inches per year}$$

What general geographic trend does rainfall follow across Texas from west to east?

Average annual rainfall increases significantly from west to east.

Which coordinate designation is associated with the Northwest Atlantic Ocean on the marine regions map?

$$40\text{W}$$

Which coordinate designation is associated with the Northwest Pacific Ocean on the marine regions map?

$$180\text{W}$$

Which coordinate designation is associated with the Southeast Pacific Ocean on the marine regions map?
