Did You Know?

"The Wave" originated as a challenge between The Seattle Sounder fans and The Vancouver Whitecaps fans in 1975 at Memorial stadium in Seattle, during an NASL soccer game. "Bill the beer man" challenged the two sides of the stadium to out yell each other. As the two sides would rise to their feet and yell, "Go Sounders" or "Go Whitecaps," it would give the appearance of waves. As they added seating at the end of the field, it went in "the round", going all around the stadium in the form of the "Wave".

Objective: I will identify the major ocean currents and circulation patterns.

Current Map

1. Pick up a world map

2. Turn to page 9-5 figure 9-2

3. Copy and label the currents on your map. Use the map on the next slide to help you identify the cold and warm currents. (please show these on your map)

Note: the map on the board and in the text don’t line up exactly but show the same thing.

Major ocean currents of the world. On this illustration red arrows indicate warm currents, while cold currents are displayed in blue.

*When done glue to pg. 44*

1. List as many types of waves you can think of.2. What do waves transfer?

3. In this picture, what is happening to the gravitational potential energy of the drop?

Pg. 46 RTW What are Waves?

1. Sound waves, visible light waves, radio waves, microwaves, water waves, sine waves, cosine waves, stadium waves, earthquake waves, waves on a string, slinky waves  - ALL types of Waves!

2. Waves transfer ENERGY!!

3. Gravitational potential energy of a water drop turns into kinetic energy, which transfers energy in the form of a WAVE!

What are Waves?

Objective: I will learn about the different parts of a wave and how energy is transferred through different mediums.

Properties of Water Tides Waves Currents

Tuesday, October 27th

= a large mass of continuously moving water. Surface Ocean Currents – the largest

currents that move across the ocean; they are like rivers that travel long distances. usually caused by wind.

Deep Ocean Currents – warm water rises at the equator, flows until it cools, and sinks at the poles. This cold water flows along the bottom toward the equator where it warms and rises.

Pg. 45 Currents

Three major factors that set ocean currents in motion:1. Wind2. Changes in sea level3. Differences in water density

Causes of Currents

The spinning Earth causes the winds and surface waters to move in a clockwise direction in the North (deflected to the east) and in a counterclockwise direction in the South (deflected to the west).

The continents deflect the currents, causing them to move in giant circles called gyres. Wind driven currents are also called surface

currents Significant b/c they move plankton across the

ocean.

Coriolis Effect

The rising of vertical currents from the deep.

Significant b/c nutrients such as phosphates and nitrates are brought up. These are important for the growth of plankton = plankton are at the beginning of the food chains.

Upwellings

Causes by wind blowing offshore or sometimes parallel to shore & the Coriolis effect

Waves and Energy

Anatomy of a Wave

A wave is the transmission of energy through matter.

Key word is “through.” When energy moves through matter as a wave, matter moves, but … - overall doesn’t shift forward or backward. - It transmits the energy to adjacent matter,

allowing the energy to continue.

Anatomy of a Wave

Does the water in a wave move? Nope! The energy is transferred. The water

molecules only move in small circles.

Anatomy of a Wave

Objective: I will be able to describe the factors that contribute to the formation of a wind driven wave: wind speed, fetch, and duration. I will also be able to describe the movement of water in a wave.

Crest= highest point above average water level

Trough= lowest point below average water level

Height= vertical measurement from trough to crest

Wavelength= horizontal distance between the peaks of two waves.

AMPLITUDE

WAVELENGTH

Deepwater Waves Occur in water that is deeper

than half their wavelength the bottom does not affect their orbital motion

Shallow-water Occur in water that is shallower

than half their wave-length The bottom creates drag that

affects their orbital motion.

Wave Characteristics

Three factors that affect maximum wave size:

1. Wind Speed= faster than the wave

2. Wind Duration= time wind blows

3. Fetch= surface area over which the wind blows

Wave Characteristics

Transverse

The motion of the medium is at right angles to the direction in which a wave travels

Stretched strings of musical instruments, electromagnetic waves, S-waves in earthquakes

LongitudinalThe particles of the medium move back and forth in the same direction in which the wave travels Sound waves, P-waves in earthquakes

Two Types of Waves

Key Terms

Distance = Rate * Time (D=RT) Rate = Distance / Time (R=D/T)

Use the equation for rate when calculating wave speed.

DiRT - Calculating Rate

Pg. 46 S.T.A.R

1. What are the three things that affect the maximum wave size?

2. What is the wave speed equation?

Objective: I will be able to describe the factors that contribute to the formation of a wind driven wave: wind speed, fetch, and duration. I will also be able to describe the movement of water in a wave.
