Questions and Answers

What are tides?

The natural change of the ocean's sea level, caused by the gravitational pull of the moon and the Sun. (correct)

Two high tides and two low tides occur each day, about every 12 hours and 25 minutes. (correct)

Tidal bulges are when tides highest points of water on Earth, caused by the gravitational pull of the moon and the force of inertia. (correct)

What are the stages of tides?

High tide: The sea level rises as the tidal crest reaches a specific location on the shore. (correct)

Spring tides: highest and lowest tides of the month, occurring when the sun, moon, and Earth is aligned. (correct)

Low tide: The sea level falls as the trough reaches a location on the shore. (correct)

Neap tides: moderate tides that occur when the sun and moon are at right angles to each other, causing lower high tides and higher low tides than average. (correct)

How are tidal waves formed? What do tides do for us?

As the Moon revolves around our planet, its gravity pulls Earth toward it. The lithosphere is unable to move much but the water above it is pulled by gravity and a bulge is created. Tides affect coastal regions in different ways. High tides push large amounts of water far up onto beaches and leave the sand sediment mixed with the water behind when the tide goes out. Therefore, tides transport sand and sediment and shape shorelines.

What is the global climate system?

The machine consists of the oceans, the atmosphere, the land surface, and the biota on land and in the oceans; in short, it consists of everything at the Earth's surface. Signup and view all the answers

Difference between natural and human-enhanced greenhouse effect?

Natural: refers to trap heat from the sun using naturally occurring greenhouse gases in the atmosphere. Essential for life on our planet. Signup and view all the answers

What is ENSO?

El Niño-Southern Oscillation (ENSO) is a climate pattern when sea temperature experiences significant changes. Signup and view all the answers

What are the phases of ENSO?

<ol> <li>El Niño a. Climate pattern that causes an increase in temperature of the sea's surface. It causes heat waves, drought, and damage to agriculture in Southeast Asia. b. The trade winds weaken or reverse direction, allowing warm water to move eastward. c. El Niño causes high temperatures in the Philippines, and opposite on the other side of our planet. 2. La Niña a. Climate pattern that causes a decrease in temperature of the sea's surface. This causes increased rain and typhoon/hurricane activity in the Pacific and Atlantic Ocean. b. Strengthening of moist easterly winds blowing towards Australia, and a subsequent increase in cloud development and rain over the longitudes. c. La Niña causes low temperatures in the Philippines, and opposite on the other side of our planet. 3. Neutral a. A period when sea temperature is neutral/normal. b. There are no significant weather events during this phase.</li> </ol> Signup and view all the answers

Study Notes

Lesson 1: Earth's Tides

Tides are the natural change in ocean levels due to the gravitational pull of the moon and sun.
Two high tides and two low tides occur daily, approximately every 12 hours and 25 minutes.
Tidal bulges are the high points of water caused by this gravitational pull.
High tide occurs when the tidal crest reaches a location on the shore, while low tide occurs when a trough reaches the shore.
Spring tides are the highest and lowest tides, occurring when the sun, moon, and Earth are aligned.
Neap tides are moderate tides occurring when the sun and moon are at right angles to Earth, resulting in lower high tides and higher low tides.

How are Tidal Waves Formed?

The Moon's gravity pulls Earth's water, creating a bulge.
Tides affect coastal regions, transporting sand and sediment.

Lesson 2: Global Climate & Interaction

What is the Global Climate System?

The global climate system involves various components (oceans, atmosphere, land surfaces, and biota) that interact to exchange, store, and release heat.

What is Climate Change?

Climate change is a long-term shift in weather patterns, temperature, precipitation, and sea levels. It can be natural or human-caused.

What is Global Warming?

Global warming is an aspect of climate change. It involves long-term heating of the Earth's climate. It can be natural or human-caused.

Lesson 3: Greenhouse Effect

What is the Greenhouse Effect?

The greenhouse effect is a natural process where gases in the atmosphere trap heat.
Greenhouse gases absorb solar radiation and release it back to Earth.
Too much greenhouse gas is not good for the atmosphere.

Lesson 3.1: ENSO

What is ENSO?

ENSO (El Niño-Southern Oscillation) is a climate pattern affecting sea temperatures.
ENSO significantly affects weather patterns globally.

What are the phases of ENSO?

El Niño:
- Increased sea surface temperatures.
- Weakened trade winds.
- Warmer water moves eastward.
- Impacts include heat waves, drought, and damage to agriculture (e.g., in Southeast Asia)
La Niña:
- Decreased sea surface temperatures.
- Stronger trade winds.
- Increased cloud development and rain in specific areas (e.g., increased precipitation in Australia)
- Impacts include higher amounts of rain and increased typhoon/hurricane activity.
Neutral:
- Normal sea surface temperatures.
- No significant weather events.
