Why is the ocean not flat?
The difference is sea level is caused by two major factors: tides and ocean currents.
Tides are mainly caused by the gravitational pull of the Moon and the Sun, acting on the Earth’s surface..
Why don’t we fall through the earth?
The attractive force of gravity acts between the center of two objects. In the case of people standing on the earth’s surface, the effect of gravity is to attract us towards the center of the earth. As a result, no matter where you stand on the earth, you don’t fall off.
What is under the sand in the ocean?
In the deepest parts of the ocean, you’ll find layers of Earth’s crust make up the ocean floor. These deepest layers are made up of rock and minerals. Unlike the soft sands along the shoreline, these deep layers of thick rock and minerals do a fine job of holding the water in the world’s oceans.
What’s beneath the ocean floor?
The ocean floor is called the abyssal plain. Below the ocean floor, there are a few small deeper areas called ocean trenches. Features rising up from the ocean floor include seamounts, volcanic islands and the mid-oceanic ridges and rises.
What keeps the oceans in place?
Gravity and inertia act in opposition on the Earth’s oceans, creating tidal bulges on opposite sites of the planet. On the “near” side of the Earth (the side facing the moon), the gravitational force of the moon pulls the ocean’s waters toward it, creating one bulge.
How does water stay on Earth while spinning?
Gravity and inertia. Gravity is a force that attracts all objects with mass (or energy) to all other objects that have mass (or energy). In the case of these pools, the gravitational attraction between Earth and the water holds them together. And yes, Earth is spinning once a day.
