it starts roughly 10 miles up.
The stratosphere isn't on earth's surface, the troposphere is. The stratosphere is the next level of the atmosphere from the troposphere. the atmosphere is about 600 miles or kilometers above earth's surface.
The atmosphere is from the area just above the ground to 1200 miles above ground
The moon is far beyond the earth's atmosphere. The boundary between the atmosphere and outer space is generally considered to be an altitude of 62 miles, although there is a noticeable effect on spacecraft as high as 75 miles. The average distance from the earth to the moon is 233,000 miles.
We think of the atmosphere as a big ocean of air around us, but the air around us is very thin relative to the size of the earth. The "thickness" of the atmosphere or the distance between the earth's surface and the "top" of the atmosphere is not exactly measurable. With increasing altitude the atmosphere fades slowly away into space. Therefore it is not easy to tell exactly how high the atmosphere really is. Perhaps 50 kilometers. (see answer "how far is it to outer space?")
Earth's closest neighboring star is the sun; about 93 million miles away.

A distance of about 1,800 miles [2,896.8 kilometers] separates the earth's mantle from the earth's crust.
Each layer of atmosphere around the Earth is found at different heights. The Troposphere is found at 4 to 12 miles, or 23,000 to 65,000 feet above the Earth.
The size of the US, in cubic miles, depends on how deep into the earth and how far up into space is considered to be part of the US.
