What are Tides?
What are Tides?
The regular rise and fall of the ocean's water level, primarily caused by the gravitational pull of the Moon and the Sun.
What is a High Tide?
What is a High Tide?
The highest point of the tide, when the water reaches its maximum height.
What is a Low Tide?
What is a Low Tide?
The lowest point of the tide, when the water reaches its minimum height.

Study Notes
Water Surrounding the Earth
- March 22nd is celebrated as World Water Day
- Earth is called the 'water planet' due to abundant water
- 71.1% of Earth's surface is covered by water
- 97% of this water is salt water (in oceans)
- The remaining 2.1% is in glaciers
- Less than 1% is fresh water (rivers, lakes, ponds, groundwater)
- Five types of oceans: Pacific, Atlantic, Indian, Arctic, and Southern (Antarctic)
- Ocean water is saline (contains salt)
Water Cycle
- Water continually changes form (liquid, gas, solid) and moves between oceans, atmosphere, and land
- This is called the water cycle
Movement of Ocean Water
Waves
- Waves are the movement of water particles up and down
- They are basically a rhythmic movement
- Wave height depends on wind speed and duration
Ocean Currents
- Continuous movement of water in a specific direction
- Two types: cold and warm currents
- Cold water is denser, so it moves slower
- Cold currents travel from poles to equator
- Warm currents travel from equator to poles
- Warm currents bring warm temperatures
- Cold currents bring cold temperatures
- The confluence of warm and cold currents creates good conditions for plankton growth (food for marine life)
Tides
- Periodic rise and fall in ocean water level, known as tides
- Two types: high and low tides
- Usually occur twice a day
- Caused by the gravitational pull of the moon and sun on Earth's surface
- The closer the moon or sun, the higher the tide
