SUBSYSTEM (LESSON 2) Flashcards
GIVE THE TECHNOLOGIES SCIENTIST ALLOWED TO STUDY EARTH IN DIFFERENT WAYS
- SUBMERSIBLE - SATELLITE
- SEISMOMETER - BUOYS
PURPOSE OF SATELLITE AND SPACECRAFT
ALLOWS US TO VIEW, PHOTOGRAPH AND MAP EARTH FROM SPACE
PURPOSE OF SUBMERSIBLE AND SHIPS
ALLOW US TO VIEW, PHOTOGRAPH AND MAP THE OCEAN FLOOR
PURPOSE OF BUOYS AND OTHER MONITORING DEVICES
PROVIDES US WITH DATA RELATED TO EVENTS SUCH AS TSUNAMIS AND EARTHQUAKES.
PURPOSE OF GIS ( GEOGRAPHIC INFORMATION SYSTEM)
IS A POWERFUL COMPUTER PROGRAM CALLED GIS HELP SCIENTIST ORGANIZE, LAYER AND INTERPRET HUGE AMOUNTS OF DATA IN ORDER TO STUDY HOW THE EARTH CHANGE OVERTIME.
DEFINE ATMOSPHERE
MEANS VAPOR. THE GASEOUS ENVELOPE SURROUNDING EARTH IS CALLED ATMOSPHERE.
LAYERS OF THE ATMOSPHERE
TROPOSPHERE, STRATOSPHERE, MESOSPHERE, THERMOSPHERE, EXOSPHERE
HIGHEST AND WIDEST LAYER OF THE ATMOSPHERE
THERMOSPHERE
HAS NO AIR MOLECULES
MESOSPHERE
CONTAINS OZONE/ OZONE LAYER
STRATOSPHERE
LAYER IN ATMOSPHERE WHERE WE LIVE IN
TROPOSPHERE
BOUNDARY OR BORDER FROM THE SPACE
EXOSPHERE
DEFINE GEOSPHERE
IT MEANS EARTH, THE ROCK, MOUNTAIN, BEACHES AND ALL OTHER PHYSICAL FEATURES OF THE EARTH MAKES UP GEOSPHERE.
DEFINE HYDROSPHERE AND GIVE ITS WATER FORMS
CONTAINS ALL THE WATER IN THE EARTH SYSTEM. WATER FORMS: RIVER, LAKE, OCEAN, LAGOON, LAKE, POND, SPRING
DEFINE BIOSPHERE
IT MEANS LIFE, ALSO KNOWN AS THE ECOSPHERE
DEFINE CRYOSPHERE (PART OF HYDROSPHERE)
-IT MEANS ICY COLD OR FROST
- IS THE FROZEN WATER PART OF THE EARTH SYSTEM
DEFINE ANTHROSPHERE (PART OF BIOSPHERE)
INTERACTIONS WHOF HOMO SAPIENS WITH ALL ASPECTS OF THE ENVIRONMENT
THE SOURCES OF THE EARTH’S ENERGY
- SOLAR ENERGY 99.895%
- GEOTHERMAL ENERGY 0.013%
- TIDAL ENERGY 0.002%
DEFINE THE THREE SOURCES OF EARTH’S ENERGY
- SOLAR ENERGY COMES FROM THE NUCLEAR FUSION REACTIONS FROM THE SUN
- GEOTHERMAL ENERGY COMES FROM THE EARTH AS RADIOACTIVE
- TIDAL ENERGY IS THE RESULT OF THE PULL OF THE MOON ON THE EARTH’S OCEANS. SLOWS DOWN EARTH’S ROTATION AND CAUSES THE OCEANS TO BULGE.
IS THE SPINNING OF A MOON OR PLANET ON ITS AXIS
ROTATION
IS PLANETS MOVEMENT AROUND A STAR OR MOON MOVEMENT AROUND A PLANET

WHAT IS EARTH’S REVOLUTION PERIOD?
365.25 DAYS
WHAT IS THE IMAGINARY LINE THAT RUNS THROUGH THE EARTH’S POLES
AXIS
EARTH’S AXIS IS TILTED TO WHAT DEGREE?
23.5 DEGREES
WHY DOES OUR SEASONS CHANGE?
SEASONS CHANGE DUE TO EARTH’S ROTATION AND EARTH’S REVOLUTION AROUND OUR SUN.
