The Study of the EarthThe Study of the Earth
Earth Science is the study of the earth and the
universe around it.
– It is the oldest observable science and is based on the accumulated body of scientific knowledge that has been passed through time

Introduction to Earth ScienceIntroduction to Earth Science
• Geology- the study of the origin, history, and processes that created the structure of the earth
• Oceanography- the study of the earth’s ocean
• Meteorology- the study of the earth’s atmosphere
• Astronomy- the study of the universe
The Scope of Earth ScienceThe Scope of Earth Science1. Astronomy
– Astronomy is the study of objects beyond Earth’s atmosphere.
– Astronomers study the universe and everything in it, including Earth’s place in space, its neighbors, and other bodies in the universe.
The Scope of Earth ScienceThe Scope of Earth Science2.Meteorology
– Meteorology is the branch of Earth science that studies the air that surrounds our planet.
– Meteorologists study the forces and processes that cause the atmosphere to change to produce weather.
– They also try to predict the weather and how changes in weather might affect Earth’s climate.
The Scope of Earth ScienceThe Scope of Earth Science3.Geology
– Geology is the study of the materials that make up Earth and the processes that form and change these materials.
– Geologists identify rocks, study glacial movements, interpret clues to Earth’s 4.6 billion-year history, and determine how forces change our planet, among many other things.
The Scope of Earth ScienceThe Scope of Earth Science4.Oceanography
– Oceanography is the study of Earth’s oceans, which cover nearly three-fourths of the planet.
– Oceanographers study the creatures that inhabit salty water, measure different physical and chemical properties of the oceans, and observe various processes in these bodies of water.

Chemistry vs. PhysicsChemistry vs. Physics
• Chemistry is the study of the properties of matter and how matter changes.
• Chemistry studies composition, structure, properties, and reactions of matter.
• Physics is the study of matter and energy and how they interact.
• Physics is concerned with the interaction between matter and energy through force and motion.
