Earth Science

• Earth Science is the study of the Earth and its neighbors in space.
• Geology: Science of the Earth
• Geology: It is the primary Earth science.
• Geology means "Study of the Earth.”
• Geology: It deals with the composition of Earth materials, Earth structures, and Earth processes.
• Geology: It is also concerned with the organisms of the planet and how the planet has changed over time
• Geologists: They search for fuels and minerals, study natural hazards, and work to protect Earth's environment.
• volcanologist braves the high temperatures and molten lava of volcanoes.
• Seismologists study earthquakes and the forces of the Earth that create them.
• Scientists interested in fossils are paleontologists
• scientists who compare other planets’ geologies to that of the Earth are called planetary geologists.
• Meteorology: Science of the Atmosphere
• Meteorology: It is the study of the atmosphere and how processes in the atmosphere determine Earth's weather and climate.
• Meteorology is a very practical science because everyone is concerned about the weather
• meteorologists work to predict or forecast the weather
• Oceanography: Science of the Oceans
• Oceanographers work to develop the ocean as a resource and protect it from human impact
• Physical oceanography is the study of the processes in the ocean itself, like waves and ocean currents.
• Marine geology uses geology to study ocean earthquakes, mountains, and trenches.
• Chemical oceanography studies the natural elements in ocean water and pollutants.
• Astronomy: Science of the Universe
• Solar flares - Strong bursts of energy from the sun
• Environmental scientists study the ways that humans interact with the Earth and the effects of that interaction
• Biogeography is a branch of science that investigates changes in populations of organisms in relation to place over time.
• limnologist studies inland waters like rivers and lakes
• hydrogeologist focuses on underground water found between soil and rock particles
• glaciologists study glaciers and ice.
• Stratigraphy is another area of Earth science which examines layers of rock beneath the surface.
• Gulf Stream is a powerful water current in the Atlantic Ocean
• The Earth’s geosphere sometimes called the lithosphere
• earth comes form the germanic word which means the ground
• minor axis - the diameter through the poles
• major axis - the diameter through the equator
• When the earth is cut in equal halves, each half is called a hemisphere.
• magnetic field shields the planet from harmful radiation from the Sun
• Earth spins on its axis, it also orbits, or revolves around the Sun, this movement is called revolution
• closest Earth gets to the Sun is perihelion
• the furthest the earth gets into sun is at aphelion
• Climate is the average temperature and weather patterns over an extended period of time
• Tropical climates are found around the equator and usually have warm temperatures all year round.
