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. (A), The global climate system is like a big machine receiving, moving, storing, transferring, and releasing heat or thermal energy. (B) Signup and view all the answers

What is climate change?

The long-term shift in weather patterns, temperature, precipitation, sea levels, etc. (A), Climate change can either be natural or man-made. (B) Signup and view all the answers

What is global warming?

An aspect of climate change, which is the long-term heating of the Earth's climate. (A), Global warming can either be natural or man-made. (B) Signup and view all the answers

What is the greenhouse effect?

Greenhouse gases are primarily made out of CO2. (Carbon dioxide). (A), A natural process that traps heat in the atmosphere, keeping the planet warm enough for life. (B), Too much greenhouse gases is not good for our atmosphere. (C), Caused by greenhouse gases, they absorb radiation from the sun and re-emit it back to Earth. (D) 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. (A), Human-enhanced: Caused by additional greenhouse gases released into the atmosphere due to human activities. Main factor for global warming on our planet. (B) Signup and view all the answers

What is ENSO?

El Niño-Southern Oscillation (ENSO) is a climate pattern when sea temperature experiences significant changes. (A), It's a natural phenomenon that significantly impacts global weather patterns. (B) 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

Flashcards

What are tides?

The natural change in ocean sea level caused by the gravitational pull of the Moon and the Sun.

What are tidal bulges?

The highest points of water on Earth caused by the Moon's gravitational pull and the force of inertia.

What is high tide?

The sea level rises as the tidal crest, the highest point of a wave, reaches a specific location on the shore.

What is low tide?

The sea level falls as the trough, the lowest point of a wave, reaches a specific location on the shore.
