Many continents contain large mountain ranges that divide the continent into different regions. In the U.S. the Rocky Mountains mark the continental divide. The presence of a large mountain range can have a big effect on seasonal weather patterns. Also, the weather and climate on one side of a mountain range may be very different from weather and climate on the other side of the range. In the case of the Rocky Mountains, the western slope and eastern slope each have very different climates and seasonal weather patterns. There are other mountain ranges in the U.S. besides the Rocky Mountains: The Grand Tetons and the Sierra Nevadas in the west, and the Appalachians in the east. Conduct an experiment comparing seasonal weather patterns on the two sides of a mountain range. Use online databases to gather data about annual temperature, humidity and precipitation patterns for locations on either side of the mountain range. You can even gather data from famous mountain ranges in other parts of the world like the Himalayas, the Alps or the Andes. Use your world atlas to find an interesting location, and then use an online database to gather your data. How do the climates compare?

When you hear the word geography, you might think of maps and names of state capitals, but the work of geographers is much more than creating maps and identifying places. Geographers look at how people, places, and Earth are connected. They study the economy, social conditions, climate, and topography of a region to help answer questions in urban and regional planning, business, agriculture, and medicine. Read more
Career Profile
The atmosphere is a blanket of gases, surrounding Earth, that creates our weather. Meteorologists study the measurements and motion of the atmosphere, and changing events within it, so that they can predict the weather. This weather forecasting helps the general public and people who work in industries such as shipping, air transportation, agriculture, fishing, forestry, and water and power better plan for the weather, and reduce human and economic losses.
