Earth ! answer the following questions.

1: what is an ocean tide? how do we measure tides?

2: if the moon's gravity causes the tidal bulge on the side of the earth facing the moon, what causes the tidal bulge on the opposite side of the earth?

3: how are the moon, earth, and sun positioned for a neap tide?

4: why do major surface current gyres in the northern hemispheres flow clockwise?

5: the equatorial currents flow westward until they run into land. list three things that can happen to the waters in these surface currents.

6: if a wind blows east across a stretch of the north atlantic ocean, in what direction will the resulting surface current move?

7: explain how a cold surface current can affect nearby continental climate?

8: why are areas of the ocean near the equator zones of up welling water

9: explain how gravity can form density currents.

that's all for now i'm going to be posting more earth science questions later.

1) (A)Tides are very long-period waves that move through the oceans in response to the forces exerted by the moon and sun. Tides originate in the oceans and progress toward the coastlines where they appear as the regular rise and fall of the sea surface. (B)Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun, and the rotation of Earth. ... To make accurate records, tide gauges at fixed stations measure water level over time.

2) Gravity is a major force responsible for creating tides. Inertia, acts to counterbalance gravity. It is the tendency of moving objects to continue moving in a straight line. Together, gravity and inertia are responsible for the creation of two major tidal bulges on the Earth

3) Position of the Earth, Moon, and Sun during Spring and Neap Tide, 1891. High tide, then, occurs under the moon, while the high tide caused by the sun, becomes, by comparison, a low tide. Such tides are called neap tides. During their prevalence, the flood is not very high, nor the ebb very low.

4) The water at the ocean surface is moved primarily by winds that blow in certain patterns because of the Earth's spin and the Coriolis Effect. ... Gyres flow clockwise in Northern Hemisphere oceans and counterclockwise in Southern Hemisphere oceans because of the Coriolis Effect. creating surface ocean currents

5) 1. Ocean waters pile up slightly

2. Equatorial Current flow turns north or south, and in each ocean basin there is an Equatorial countercurrent

3. Return surface waters to the east sides of the ocean basins

6) it will result in the current flowing Clockwise

7) Ocean currents can effect the weather by carrying cold or warm water far away from its source. Global winds pick up the rest of the heat from the surface waters and move it through the atmosphere.

8) Upwelling exists in places where the sea level is lower than average. The Coriolis Effect and Ekman Spiral also play apart in dragging the water into major ocean gyres.

9) Currents may also be generated by density differences in water masses caused by temperature and salinity variations. These currents move water masses through the deep ocean—taking nutrients, oxygen, and heat with them.
