Weather and Climate

What are the factors that affect climate? 
Earth-Sun Relationships 
The amount of sunlight that reaches the earth varies depending on Earth's tilt and rotation. Earth's revolution, or yearly orbit around the sun, also affects the amount of sunlight each area receives, resulting in seasonal changes.
How does the Sun-Earth spatial relationship affect weather conditions and climate?

Influences on Climate Regions
Climate refers to weather patterns that occur in a place over time. Although the earth's climates are influenced by many factors, the most important is the earth's position in relation to the sun. Other influences relate to the specific location of a place and the features that exist there. World climate regions vary greatly, and each supports characteristic vegetation.
How does elevation, latitude, wind systems, ocean currents, position on a continent, and mountain barriers influence temperature, precipitation, and distribution of climate regions?
