Question 9 1pts of the Earth's atmosphere is below 26km. O 50% O 100% O 48% 98%

Answer 1

Answer:

Earth's atmosphere is below 26 km is composed of  98%.

Explanation:

• Troposepher marks the boundary for most of the convective activity to take place on the surface of the earth's this place consist of 99% of the total space for the all-weather phenomenon to occur and as a result of which is considered to a homogeneous sphere.

• Here the water vapor, dust particles, and other gaseous bodies are found and thus this layer is a life-supporting layer full of oxygen and hence, comprise all biotic components like the plants, animal and man.

• Above this layer there are drastic changes in temperature with increasing height as the atmospheric pressure at higher altitudes decreases and so does the life-supporting layer, it can be noted that the layer that protects the earth i.e ozone is found in the mesosphere at an altitude of 30 kilometers.

• Rest most of the weather phenomenon takes place here as it sets the stage for weather patterns as convective currents coming from the equator can't pass this layer.
