One of the ways is that it carves it by weathering and eroding it away.
Erosion
The tectonic plates below earths surface shape earths landforms
Weathering and erosion shape earths surface by changing earths surface by having extreme forces that change earth.
Tornadoes do not effectively shape the earth's surface, they are too fleeting.
The Earths surface changes shape when plates collide when the earths surface overlaps or when there are Earthquakes.
our activities, movements and settlements shape the Earths surface.
Landform.
There is no such thing as half of the Earth. If you are referring to half of the spherical shape of the Earth then it will be a hemisphere.
Weather erosion is where the weather effects the shape of the earths surface
The earth's surface features are, all the shapes and forms on the earth's surface; mountains, valleys, oceans, lakes, rivers, volcanoes, deserts, glaciers etc. just like your nose, eyes, lips, ears, chin, eyebrows and shape are your facial features.
During the Great Ice Age glaciers shaped the earths surface created a mitten shape.
A hemisphere.
