q10. what is the difference in meaning between the term weather and climate?

Explanation:

The troposphere is the lowest layer of the Earth's atmosphere. It contains about 75 - 80% of the total atmospheric mass. Weather phenomena occur in this layer. The other options are incorrect:

• The part of the atmosphere that absorbs optical light is not a defining characteristic of the troposphere.
• The ozone layer (in the stratosphere) absorbs ultraviolet radiation.
• There is no layer in the atmosphere that is mainly known for absorbing X - rays.
• The highest layer in the atmosphere is the exosphere.

Answer:

the lowest layer in the atmosphere that contains most of the atmospheric mass
