What is the structure of Water?

H2O, two parts hydrogen, one part

oxygen.

Hydrogen and Oxygen give Water a polar

nature. How?

Hydrogen has a +1 charge.Oxygen has a -2 charge.

What are 3 special properties of water?

Surface TensionCapillary Action

Specific Heat

Explain what Specific Heat means

Specific Heat: amount of energy needed to increase

temperature by 1⁰C

Final Jeopardy

Define 3 parts / characteristics of a wave.

1. Crest: highest point2. Trough: lowest point3. Wavelength: distance between 2

crests / troughs4. Wave Height: distance from

crest to trough5. Frequency: number of waves

during a certain interval of time

What causes tides, and how often do tides occur?

The gravity of the Moon & Sun cause tides. Tides occur every 12½ hours.

What are Spring & Neap tides, and when do they occur?

Spring tide is the greatest difference between high & low tide. Neap tide is the

smallest difference.

Waves do not move water forward. Explain why,

and what happens when waves reach the shore.

Wind energy is transferred through the water. Near the shore, wave

height increases as length decreases, causing wave to break.

Final Jeopardy

Two natural disasters we have studied this chapter are...

Tsunamis and El Nino

What causes a Tsunami and where does it occur?

An earthquake in the ocean floor.

What is Upwelling and how does El Nino affect it?

Upwelling is when warm water is pushed away by wind and cold

water rises. El Nino brings more warm water, preventing upwelling.

What is a Tsunami like in the open ocean compared to as it reaches shore? What causes

this difference?

In the open ocean, tsunamis have a small wave height, but massive wavelength. On shore, the length rapidly decreases from

friction, causing the height to spike.

Final Jeopardy

What are the 2 types of currents?

Surface currents and Deep currents.

What causes a surface current? What is the

strongest surface current in the N. Atlantic Ocean?

Surface currents are driven by wind. The Gulf Stream.

What kind of currents affect climate and how?

Surface currents heat or cool air above them, affecting weather of

land nearby.

What is the Coriolis Effect?

The rotation of the Earth causing the path of winds

and waves to curve in relation to Earth’s surface.

Final Jeopardy

What do we mean by water “cycle?”

Water moves from bodies of water, land and living things to the atmosphere

and then back.

What are the 3 “steps” or phases of the water cycle?

Evaporation, Condensation and

Precipitation.

What living things give off the most water? What

is this called?

Plants release water through Transpiration.

Explain how a cloud forms.

Water vapor is carried to the colder upper atmosphere. It

condenses on tiny dust particles in the air.

What 4 properties of ocean water change with depth and how do they change as you go deeper?

603010

STOP

As depth increases…1. Temperature decreases2. Salinity increases3. Density increases (salty & cold)4. Pressure increases
