Answer:
Step-by-step explanation:
1. Weather describes the condition of the atmosphere over a short period of time e.g. from day to day or week to week, while climate describes average conditions over a longer period of time. ... This variability can be seen in the long-term daily, monthly, and yearly averages for different weather conditions.
2. The birth of modern astronomy occurred during the 1500s and 1600s. Scientist Johannes Kepler, who lived from 1571 to 1630, established that the planets revolve around the sun, thus establishing one of the two primary motions of the earth. Sir Isaac Newton expanded on Kepler’s work, establishing how gravity affects planetary movement. Today, we know that the earth has two primary motions, rotation and revolution, which are responsible for life cycles of all living things on Earth.
Rotation
The first primary motion of the earth is rotation. The earth rotates in a counterclockwise pattern, spinning on its axis once every 24 hours. The earth wobbles as it rotates, similar to a spinning top because the rotation of the earth occurs at a slight tilt. The earth is tilted at approximately 23.5 degrees. The tilt of Earth, as it rotates, creates different gravitational forces at the north and south poles.
Revolution
As the earth rotates on its axis, it also revolves in orbit around the sun. It takes exactly 365 days for Earth to make one full trip around the sun -- our definition of a year. The earth follows a circular path as it travels around the sun in a counterclockwise pattern. The path that the earth travels is therefore referred to as the plane of the elliptical.
