How does the author introduce earths movements and how they affect time and seasons on earth

But Earth's distance from the sun doesn't change enough to cause seasonal differences. Instead, our seasons change because Earth tilts on its axis, and the angle of tilt causes the Northern and Southern Hemispheres to trade places throughout the year in receiving the sun's light and warmth most directly.

an aneroid barometer is different from a mercury barometer in that it provides readings that increase as air pressure increases.
