Geology Geology investigates the composition, structure, and history of the earth. Geologists analyze how such forces as earthquakes, volcanic eruptions, and wind or water erosion change the earth's surface. They also study meteorites and materials brought back from the moon. Geochronology seeks to determine the age and history of the earth and its parts. Meteorology Meteorology is the study of the earth's atmosphere and the conditions that produce weather.
Meteorologists try to predict the weather.
They work to develop improved instruments for collecting data about the atmosphere. They also seek better techniques to make weather forecasting more exact. Climatologists analyze weather trends to determine the general pattern of weather that makes up an area's climate. Physics Physics is concerned with matter and energy. Physicists study mechanics, heat, light, sound, electricity, magnetism, and the properties of matter.
