The troposphere because it has half of all air in the Atmosphere
<span>Earthquakes usually occur near deep mountain ranges deep sea trenches and volcanic activity</span>
What do you call the lines on a topographic map that indicate the elevation of the land forms?
topographic lines
The four seasons happen because of the tilt of the earth axis. During different times of the year, the rays of the sun hit different parts of the earth more directly.
The angle of the earth's tilts the northern hemisphere towards the sun during summer season while the southern hemisphere is tilted away causing winter.
Without the tilt of earth, there would be no seasons. Regions along the equator would be always be warm and sunny while those in the southern and northern hemisphere would be stuck in a gradual gradient of cold and hot.
Well it's the core, like a core of an apple. The center part.
