Hi mam

[@AnnieGrace727]

00:09 Today's class will discuss the importance of water in geography. 02:40 Importance of water and an overview of the class content 07:03 Only 2.7% of water on Earth is fresh and consumable. 09:15 Freshwater is stored in glaciers, ice caps, and underground water. 13:47 Water cycle and precipitation explained 16:16 Tides are the periodic rise and fall of sea water 20:19 Gravitational force pulls towards the center, centrifugal force acts outwards 22:16 Tides are formed due to the gravitational forces of the Sun and Moon. 26:27 Spring tide occurs when the Sun and the Moon are aligned with Earth. 28:52 Gravitational force creating high and low tides 33:04 Waves are ripples generated on water surface. 35:09 Tsunamis occur due to disturbances on the ocean floor, such as earthquakes, volcanic eruptions, or landslides. 39:17 Warm and cold currents flow in opposite directions 41:39 Ocean currents are the flow of water on the surface in a definite direction 46:02 Spring tides result in very high waves 48:16 Understanding movement in the ocean as circulation. 52:46 Tides are caused by gravitational pull and centrifugal force 55:04 Importance of water is highlighted by the slogan 'every drop counts' 59:08 Cold currents carry water from poles to the equator.

Amazing video.... So helpful thanxx byjus ❤🎉

[@bloosomvibes1390]

HW ANSWERS 1. Seas around japan are good for fishing but when the warm and cold current meets the climate becomes foggy making it difficult for navigation 2. Neap tides: when the moon is in its first and last the ocean water gets diagonally drawn away by the gravitational pull of sun and moon resulting low tides Spring tides: when it is full moon and new moon day the earth, the sun, and the moon are at the same line and the tides are the highest
