EARTH SCIENCE THE STUDY OF THE STRUCTURE, COMPOSITION AND PROCESSES.

ASTRONOMY
Branches of Earth Science
• Geology is the study of the solid Earth
• Anything and everything that has to do with the solid Earth is part of geology
• Most geologists specialize in a particular aspect of the Earth
• A volcanologist studies volcanoes
• A seismologist studies earthquakes
• A paleontologist studies fossils
GEOLOGYTHE STUDY OF THE ORIGIN (BEGINNING), HISTORY, AND STRUCTURE AND THE PROCESSES THAT SHAPE THE EARTH.
OLOGY: LATIN PREFIX THAT MEANS WORD OR THE STUDY OF.
GEOLOGIST
VOLCANOLOGIST A GEOLOGIST THAT STUDIES VOLCANOES.SEISMOLOGIST A GEOLOGIST THAT STUDIES EARTHQUAKES.

Oceanography Water Water Everywhere
• When studying caves in Florida & the Bahamas he found stalactites & stalagmites
• This indicates that the caves were above sea level at one time
• Stalactites grow down from the top of cave from dripping water
• Stalagmites grow from the floor of the cave up from the minerals in the water
OCEANOGRAPHYTHE EXPLORATION AND STUDY OF THE SEA OR OCEAN.

Oceanography Water Water Everywhere
• Physical oceanographers study things like waves and ocean currents
• Biological oceanographers study the plants and animals that live in the ocean
• Geological oceanographers study the ocean floor
• Robert Fronk is an oceanographer that studies under water caves
Oceanography Water Water Everywhere
• John Trefry another oceanographer discovered black smokers in a minisub called Alvin
• Black smokers are a type of hydrothermal vent which is a crack in the ocean floor that spews super heated water & minerals from inside the Earth onto the ocean floor
• At one time it was believed that life could not exist without sun light (but life thrives near Black smokers)
OCEANOGRAPHYTHE EXPLORATION AND STUDY OF THE SEA OR OCEAN.JOHN TREFRY USED THE MINSUBTO REACH THE
DEEP OCEAN FLOOR
OCEANOGRAPHYALVIN IS A DEEP SUBMERGENCE VEHICLE (DSV) OWNED BY THE U.S. NAVY. IT CAN STAY DOWN FOR 8 HOURS AT A DEPTH OF 14,000+ FEET.

OCEANOGRAPHYBLOOD-RED TUBE WORMS
FOUND AROUND HYDROTHERMAL VENTS, THEY CAN GROW AS LONG
AS 3.5m
GEOLOGIST
METEOROLOGY: THE SCIENCE THAT DEALS WITH THE ATMOSPHERE AND ITS PROCESSES, ESPECIALLY WEATHER AND CLIMATE.
Meteorology It’s a Gas• Meteorology is the study of the entire
atmosphere
• Anytime you talk about the weather you are discussing Meteorology
• The most common career in meteorology is weather forecasting
GEOLOGIST
HURRICANE ANDREW: A HURRICANE THAT STRUCK SOUTH FLORDIA ON AUGUST 24, 1992. IT IS THE MOST COSTLY NATURE DISASTER IN US HISTORY. DAMAGE AS MUCH AS $30 BILLION.
ASTRONOMY: THE STUDY OF THE UNIVERSE AND ALL THE CELESTIAL BODIES IT CONTAINS.
Astronomy Far Far Away• Astronomy is the study of all physical things
beyond the Earth
• They study stars, planets, and moons
• Early astronomers used only their eyes to observe the stars and the moon
• Only a couple of centuries ago they started using optical telescopes
• These days we observe stars using radio, x-ray, inferred, ultraviolet, and gamma ray telescopes
Astronomy Far Far Away• OPTICAL TELESCOPES:
• USE LIGHT AND LENS TO MAGNIFY AN OBJECT.
Astronomy Far Far Away• RADIO TELESCOPES: ALSO
CALLED RADIO ANTENNAS: THEY PARABOLIC DISH THAT PICK UP EMISSION FROM ASTRONOMICAL OBJECTS.
GALILEO GALILEI
IN 1609 USED THE OPTICAL TELESCOPE
1ST PERSON TO SEE CRATERS ON THE MOON
DISCOVERED THE 4 MOONS AROUND JUPITER
OBSERVED PHASES OF VENUS
Special Branches of Earth Science
• Sometimes Earth sciences find themselves in careers that rely on life, chemistry, physics, and other areas of science
• Ecologists study ecosystems, an ecosystem is a community of organisms and their nonliving environment
• Geochemists combines the studies of geology and chemistry
Special Branches of Earth Science
• Environmental science is the study of how humans interact with the environment
• Geographers study the surface features of the Earth
• Cartographers make maps of the Earth’s features
