WHAT ARE THE

FOUR MAIN

BRANCHES OF

EARTH SCIENCE?The four branches of Earth science are meteorology, astronomy, geology, and oceanography. Earth science is the study of the basis and structure of planet Earth

METEOROLOGY - STUDY OF THE ATMOSPHERE, WEATHER, AND STORMS.

OCEANOLOGY - STUDY OF THE OCEAN REALM IN ALL

ITS ASPECTS.

ASTRONOMYASTRONOMERS - SCIENTISTS WHO STUDY THE UNIVERSE, GALAXIES,

AND STARS.

GEOLOGY IS THE STUDY OF THE ROCKS, PROCESSES, AND HISTORY OF EARTH

ASTRONOMY VS. METEOROLOGY

ASTRONOMY METEOROLOGY

GEOLOGY AND OCEANOGRAPHY

GEOLOGY OCEANOGRAPHY

ASTROLOGY IS A

FIELD OF STUDY

THAT IS NOT SCIENCEAstrology, or astromancy, consists of several systems of divination based on the premise that there is a relationship between astronomical phenomena and events in the human world.

HYDROLOGY IS THE STUDY OF THE MOVEMENT, DISTRIBUTION, AND QUALITY OF WATER ON

EARTH AND OTHER PLANETS, INCLUDING THE HYDROLOGIC CYCLE, WATER RESOURCES AND

ENVIRONMENTAL WATERSHED SUSTAINABILITY.

GEOLOGISTS BELIEVE THE EARTH WAS ACTUALLY ONCE

A SPHERE OF INTERSTELLAR GASSES.

EARTHQUAKES ARE DEVASTATING PHENOMENON THAT

OCCUR ALONG PLATE BOUNDARIES

UNDERSEA MOUNTAIN RANGES WERE DISCOVERED IN THE

1960S.

WEATHER BALLOONS, WEATHER SATELLITES, AND WEATHER

STATIONS ARE ALL TOOLS USED BY THE METEOROLOGIST

ROTATION IS IMPORTANT IN TORNADO FORMATION.

THE EARTH'S CRUST IS DIVIDED INTO SEVEN MAJOR PLATES

71 % OF THE EARTH IS COVERED BY WATER.

THE JET STREAM IS MADE OF HUGE MASSES OF RAPIDLY

MOVING AIR MILES ABOVE THE EARTH’S SURFACE

FOR THOUSANDS OF YEARS PEOPLE BELIEVED THE

EARTH WAS THE CENTER OF THE UNIVERSE

BACK THEN NOW

A STATEMENT THAT CAN USUALLY BE WORDED IF, THEN, AND BECAUSE IS CALLED A HYPOTHESIS

A GOOD HYPOTHESIS IS ONE THAT CAN BE TESTED

METEORITES MAY HAVE BEEN THE CAUSE FOR THE

EXTINCTION OF DINOSAURS.

A GOOD SCIENTIST WILL REPEAT AN EXPERIMENT OVER AND OVER

AGAIN TO ENSURE THEY ALWAYS GET THE SAME RESULTS.

QUANTITATIVE DATA USES MEASUREMENTS THAT CAN BE RECORDED IN A TABLE OR CHART

THE INDEPENDENT VARIABLE IS THE ONE BEING

MANIPULATED BY THE EXPERIMENTER

THE CONTROL GROUP IS THE PART OF AN EXPERIMENT THAT

IS USED IN COMPARISON TO THE EXPERIMENTAL GROUP

SCIENTIFIC METHOD STEP 1: MAKE OBSERVATIONS - ASK A QUESTION

GALILEO IS CONSIDERED THE FOUNDER OF MODERN

EXPERIMENTAL SCIENCE.
