The Earth's atmosphere extends anywhere from 250-400 miles off the surface, depending on where you are standing. Near the equator, it is thicker due to the heat from the surface and cloud reflection, and the high moisture and humidity.
From wikipedia.com (http://en.wikipedia.org/wiki/Earth#Atmosphere): "The Earth's atmosphere has no definite boundary, slowly becoming thinner and fading into outer space. Three-quarters of the atmosphere's mass is contained within the first 11 km (about 4 mi) of the planet's surface."
It could be that you intend to ask another question and were unsure how to ask it. Obviously enough the entire body of the earth is orbiting the sun, but it is the center of gravity that comes close to tracking the actual line of the orbit. [Here I am unsure; it may be the barycenter, the center of gravity of the earth-moon system, that closely or exactly tracks the actual orbit.] The actual orbit, then, intersects the surface of the earth at 2 points at any given time. Since the earth is spinning as it orbits, the two surface points are constantly on the move. It must happen from time to time that a person's body actually occupies the line of earth's orbit, for the tiniest fraction of a second. If there were no axial tilt, the orbit would always intersect earth's surface at some point along the equator, or extremely close to it. Because of the axial tilt, the geometry gets a little more complicated, but the intersection of orbit and surface would be within the tropics most of the time, and possibly just outside the tropics for some length of time around the equinoxes. It's the curve of the orbit that makes it difficult to get a good mental image.

What layer of the atmosphere is adjacent to the surface of the earth?
The layer of the atmosphere adjacent to the surface of the Earth is the troposphere. It is where most weather activity occurs, contains about 75% of the atmosphere's mass, and is where we live and where our weather takes place.
What do you call an object that survives earth's atmosphere and strikes the surface?
An object that survives Earth's atmosphere and strikes the surface is called a meteorite. It is a fragment of a meteoroid that has passed through the atmosphere and landed on Earth.
Where is about 90 percent of earth's atmosphere found?
The troposphere, the lowest layer of Earth's atmosphere, contains about 90% of the Earth's atmosphere. This layer extends from the Earth's surface to about 8-15 kilometers above sea level.
Part of tge earths atmosphere closest to its surface?
The part of Earth's atmosphere closest to its surface is known as the troposphere. It extends from the Earth's surface up to an average altitude of about 7-10 kilometers. The troposphere is where most weather events occur and where almost all of Earth's clouds and precipitation are located.
Which layer of the atmosphere is closer to earth's surface?
The troposphere is the layer of the atmosphere closest to the Earth's surface. It extends from the surface up to about 10-15 kilometers in altitude. This layer is where most weather phenomena occur.
What is the distance from earth's surface to the end of earths atmosphere?
The Earth's atmosphere extends anywhere from 250-400 miles off the surface, depending on where you are standing. Near the equator, it is thicker due to the heat from the surface and cloud reflection, and the high moisture and humidity.
Which properties are most important to sustaining life on Earth?
distance from Sun, surface temperature, and atmosphere of oxygen
Is the moon in the earths atmosphere?
No, the Moon is not in Earth's atmosphere. The Earth's atmosphere extends about 480 kilometers above the surface, while the Moon is about 384,400 kilometers away from Earth. The Moon is in space, orbiting around the Earth.
What is the thickness of the atmosphere?
venus has thick posnis atmosphere
What keeps Earth's atmosphere close to the surface?
The gravitational pull keeps the Earth's atmosphere close to the surface...
Does the distance from the sun affect the earth's temperature?
Because of the Earths atmosphere, the distance from the Sun, does not affect the temperature on the surface of the Earth. In the northern hemisphere, we are closer to the Sun in winter and the furthest away in summer.
What is distance of atmosphere from the surface of sea?
9000km
How can water in the atmosphere cycle back to the surface of the Earth?
Water in the atmosphere precipitates. And in this manner it returns back to earth's surface.
What layer of the atmosphere is adjacent to the surface of the earth?
The layer of the atmosphere adjacent to the surface of the Earth is the troposphere. It is where most weather activity occurs, contains about 75% of the atmosphere's mass, and is where we live and where our weather takes place.
