Earth and its Spheres

The difference between WEATHER and CLIMATE is:

• Weather refers to short-term atmospheric conditions, while climate refers to long-term patterns.

• Weather and climate both describe long-term atmospheric patterns.

• Climate is the daily change in temperature, while weather is the yearly average.

• Weather is only about rainfall, while climate is only about temperature.

One major factor that affects the overall environment and climate is the ​ (a)   of the Earth in relation to its orbit around the Sun.

• rotation

• distance

• speed

• tilt
