Well the Earth is round because of gravity. Everything has gravity, even a pebble, however the force is so weak compared to earths gravity it is not effective.
When bits if rock started joining together 5 and a half billion years ago, they started forming a large piece of rock. As this got over a certain size, its own gravity caused it to become a sphere, and that's how its got it's basic shape.
However the earth has also been shaped by meteors hitting the surface, tectonic movement (earthquakes) and (mainly) volcanoes, which create a new surface when the lava cools down.
That's a very brief explanation, sorry if it isn't good enough.
What else can I help you with?
What is the earths shape called?
The surface of the earth is called the crust. I hope this is the answer you need.
The crust is only what of earths thickness?
half of earths layer
What is the earths under crust surrounded by?
Earths under crust surrounded by Upper Mantle (35-60 km) .The mantle is composed of sillicate rocks that are rich in iron and magnesium relative to the overlying crust.
How do floods affect the earths crust?
it gets soggy
Is it true that earths crust contains most of earths mass?
No. The crust contains a small fraction of earth's mass. Most of the mass is contained in the mantle.
What is a change in the volume or shape of earths crust?
Deformation
Any change in the volume or shape of the earths crust called?
after shock
How does tension change the shape earths crust?
because when it acts on the surface it stretches the rock to make craters or " dents" on the crust.
What is the size of the earths crust?
The Earths crust is approximately 650 km deep.
The process that shape the earths crust by forming new features are called?
The process that shapes the Earth's crust by forming new features is known as tectonic activity. This includes processes like plate tectonics, volcanic activity, and mountain-building. These processes create and modify the landforms on Earth's surface.
What causes the earths crust to rise and fall?
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
What is the earths shape called?
