🌊 Tides in Relation to the Moon

🌕 1. Gravitational Attraction

The Moon’s gravity pulls on the Earth — and especially on its oceans, since water moves easily.

This pull causes the water on the side of the Earth facing the Moon to be drawn slightly toward it, creating a bulge (a high tide).

---

🌍 2. Inertia and the Second Bulge

On the opposite side of the Earth (away from the Moon), water forms another bulge.

This happens because the Earth itself is pulled slightly more toward the Moon than the water on the far side — so the water there is “left behind” due to inertia.

As a result, there are two high tides and two low tides on Earth each day.

---

🕒 3. Earth’s Rotation

The Earth rotates once every 24 hours, so most coastal areas experience two high tides and two low tides about every 24 hours and 50 minutes (the extra 50 minutes comes from the Moon’s orbit around Earth).

---

🌑 4. Spring Tides (Strongest Tides)

During the New Moon and Full Moon, the Sun, Moon, and Earth are in a straight line (called syzygy).

The gravitational forces of the Moon and Sun combine, producing higher high tides and lower low tides — called spring tides (not related to the season).

---

🌓 5. Neap Tides (Weakest Tides)

During the First Quarter and Third Quarter phases, the Sun and Moon are at right angles relative to Earth.

Their gravitational pulls partially cancel out, causing lower high tides and higher low tides — these are neap tides.

---

☀️ 6. The Sun’s Role

The Sun also affects tides, but its gravitational pull is less than half as strong as the Moon’s because it’s much farther away.

Still, when the Sun and Moon align, their combined effect strengthens the tides.

Ocean currents

- are large-scale movements of seawater that flow continuously through the world’s oceans, driven by wind, Earth’s rotation, salinity, temperature differences, and tides. They play a crucial role in regulating global climate, transporting heat, nutrients, and marine life.

Here’s an overview of the major ocean currents of the world, organized by ocean:

---

🌍 Atlantic Ocean

North Equatorial Current – westward flow near the equator.

South Equatorial Current – westward, south of the equator.

Gulf Stream – warm current flowing northward along the east coast of North America, then eastward toward Europe.

North Atlantic Drift – extension of the Gulf Stream across the Atlantic toward Europe.

Canary Current – cool current flowing southward along the coast of northwest Africa.

Brazil Current – warm current along Brazil’s coast, flowing south.

Benguela Current – cold current along southwest Africa, flowing north.

---

🌍 Pacific Ocean

North Equatorial Current – westward near the equator.

South Equatorial Current – westward south of the equator.

Kuroshio Current – warm current flowing northward along Japan’s east coast.

North Pacific Drift – eastward extension of the Kuroshio, across the Pacific.

California Current – cold current flowing southward along the west coast of North America.

East Australian Current – warm current flowing south along Australia’s east coast.

Peru (Humboldt) Current – cold current flowing north along South America’s west coast.

---

🌍 Indian Ocean

North Equatorial Current – westward, north of the equator.

South Equatorial Current – westward, south of the equator.

Somali Current – seasonal current (reverses with monsoons).

Agulhas Current – warm current flowing south along Africa’s east coast.

West Australian Current – cold current flowing northward along Australia’s west coast.

Mozambique Current – warm current flowing between Madagascar and Mozambique.

---

🌍 Southern Ocean

Antarctic Circumpolar Current (West Wind Drift) – strongest current in the world, flowing continuously eastward around Antarctica.

East Wind Drift – flows westward closer to Antarctica.

---

🌍 Arctic Ocean

Less defined large-scale currents, but notable flows include:

Beaufort Gyre – a circular current in the Arctic Ocean.

Transpolar Drift – carries ice and water from Siberia across the Arctic toward the Atlantic.

---

✅ Key Point:

Warm currents usually flow away from the equator toward the poles (e.g., Gulf Stream, Kuroshio).

Cold currents usually flow from the poles or deep water toward the equator (e.g., Labrador Current, Humboldt Current).
