TRANSCRIPT
NITROGEN CYCLE
• The movement of nitrogen from the nonliving environment into living things and back
WATER CYCLE
• The continuous movement of water through the atmosphere, the ground, bodies of water, and living things
CARBON CYCLE
• The movement of carbon from the nonliving environment into living things and back
POLLUTION
• The presence of harmful of unwanted levels of substances in the environment
ROCK CYCLE
• The continual process by which new rock is formed from old roc k material
LITHOSPHERE
• “Rock Sphere” – the cool, rigid, outermost layer of the Earth that is divided into pieces called tectonic plates
IGNEOUS
• Rock that forms when hot, liquid rock cools and hardens
SEDIMENTARY
• Rock that forms when pieces of rocks or minerals are “glued” together
METAMORPHIC
• Rock that forms when existing rock is heated and squeezed deep inside the Earth
UPLIFTING
• The rising of regions of Earth’s crust to higher elevations
WEATHERING
• The process by which water, ice, wind, and heat act to break down rocks
EROSION
• The process by which wind, water, ice, and gravity remove and transport material from one place to another
DEPOSITION
• Process by which sediments are deposited/dropped in a new location
LAVA
• Magma that reaches the Earth’s surface
MAGMA
• Hot, liquid rock material
THEORY OF CONTINENTAL DRIFT
• The theory that continents can drift apart from one another and have done so in the past
THEORY OF PLATE TECTONICS
• The theory that the lithosphere is divided into tectonic plates that move around on top of the asthenosphere
CONVERGENT BOUNDARY
• The boundary between two colliding tectonic plates
DIVERGENT BOUNDARY
• The boundary between two tectonic plates that are moving away from each other
TRANSFORM BOUNDARY
• The boundary between two tectonic plates that are sliding past each other
SUBDUCTION
• When oceanic lithosphere sinks down into the asthenosphere at a convergent boundary
TECTONIC PLATE
• Huge pieces of the lithosphere that move around on top of the asthenosphere.
CONVECTION CURRENTS
• The circular motion of liquids or gases caused by density differences that result from temperature differences
FAULT
• The type of strain that occurs when rocks break because of stress
FOLD
• They type of strain that occurs when rocks bend because of stress
NORMAL FAULT
• A fault in which the hanging wall moves down because of tension.
REVERSE FAULT
• A fault in which the hanging wall moves up because of compression.
STRIKE-SLIP FAULT
• A fault in which the plates move horizontally past each other because of shearing.
TENSION
• A force that causes rocks to be pulled apart
COMPRESSION
• The type of stress in which an object is squeezed, as when two plates collide
SHEARING
• A force that causes rocks to slide horizontally past each other
