"Altitude" just means "height". You've essentially asked how high a height is. Perhaps you see why we can't answer this.
False; Earth's atmosphere does not end abruptly at an altitude of 40 km.
Magnetosphere.
The International Space Station (ISS) orbits at an altitude of 278 to 460 km (173 to 286 miles), and orbits the Earth about once every 92 minutes.
It depends on the given orbit, but most astronauts would be on near earth orbit vehicles like the International Space Station (ISS). This orbits the earth once every 91 minutes.
The stratospheric ozone layer forms at high altitude. It is 25 km.
An average plane flies between 5 to 10 km above the surface of the earth. Planes cannot fly below or above the altitude. After this altitude there is not much air.
You don't have to be standing on the ground to reach the maximum altitude of Earth so the answer is "everywhere". The Earth's atmosphere is about 300 miles (480 km) thick, but most of the atmosphere (about 80%) is within 10 miles (16 km) of the surface of the Earth.
The stratosphere is situated between about 10 km (6 mi) and 50 km (30 mi) altitude above the surface at moderate latitudes, while at the poles it starts at about 8 km (5 mi) altitude.
False; Earth's atmosphere does not end abruptly at an altitude of 40 km.
The atmosphere begins at the surface of the Earth and extends to space. The upper levels are the thermosphere (up to about 500-650 km altitude) and the exosphere (generally from 500 to 2000 km altitude but is nearly a vacuum).
By convention in the aerospace industry, Space is considered to be above an altitude of 100 km from Earth's surface.
The ISS orbits at an altitude of 400 km (250 miles) above Earth.
Varies between apogee and perigee of 346 and 336 km with a decay of about 2 km a month.
A satellites period, the time it takes it to go around the earth, is determined, in part, by its altitude. The further away it is then the longer it will take. You can calculate an altitude where it will take just one day to make an orbit. If this is done then though the satellite orbits the earth it appears to be stationary above one point of the earth. This orbit must be above, or very near to, the equator. For the earth this altitude is approximately 36,000 km (22,000 miles)
The ISS is maintained at an orbital altitude between 330 km (205 mi) and 435 km (270 mi).
The stratosphere is normally considered to extend from about 11 km to 50 km above the earth's surface (7 - 31 miles).
It is 87 km of altitude.
