ii AIR MASSES Air Mass is a large body of air with uniform characteristics horizontally mP Cool Moist Warm Moist cP Dry Dry Hot cT mT Cool Dry mP Cool Moist Warm Moist mT mT

Page 7

iii TYPES OF AIR MASSES CONTINENTAL AIR MASS c A dry air mass that forms over land MARITIME AIR MASS m A humid air mass that forms over oceans POLAR AIR MASS P A cold air mass that forms north of 50 north latitude and south of 50 south latitude and has high air pressure TROPICAL AIR MASS T warm air mass that forms in the tropics and have low air pressure the air is hotter so it is less dense

Page 8

iv WARM FRONTS Warm Fronts occur when moist warm air mass slides over a cold air mass forming clouds and causing a gentle rain r Wa ir A m Cold Air Temperature and humidity increase as the pressure decreases

Page 9

v COLD FRONTS Cold Fronts occur when cold air pushes under the warm air forcing the warm air to rise Cold Air Warm Air Temperature and humidity decrease and the pressure increase

Page 10

vi OCCLUDED FRONTS Occluded Fronts occurs when a warm air mass gets caught between two cold air masses causing the warm air mass to rise as the cold air masses meet in the middle Warm Air Cold Air Cold Air Temperature drops and could bring strong winds and heavy precipitation

Page 11

iv CLOUDS In order for Clouds to form air must be at its Dew Point for water vapor to crystalize The four main types of clouds are Cirrus Cumulus Nimbus and Stratus Clouds Above 8km Below 8km CUMULUS STRATUS CIRRUS NIMBUS

Page 20

CIRRUS CLOUDS are wispy white clouds at a high altitude made up of mostly ice crystals that predict a soon change in weather CUMULUS CLOUDS are thick fluffy clouds that usually seen on a nice or sunny day NIMBUS CLOUDS are dark gray and usually holding rain or another form of precipitation STRATUS CLOUDS form in low dark layers that usually covers all of most of the sky

Page 21

v CORIOLIS EFFECT the Coriolis Effect causes winds to curve to the right in the northern hemisphere and to the left in the southern hemisphere due to the Earth s rotation Intended Path ACTUAL PATH Equator ACTUAL PATH Intended Path

Page 22

vi OROGRAPHIC EFFECT the Orographic Effect changes to air flow when the topography of the land forces the air up the side of a mountain

Page 23

WINDWARD SIDE 1 2 LEEWARD SIDE 3 1 Moist air encounters a mountain range and is forced upward As the air rises it cools 2 Air cools to the dew point forming clouds it rains and most or all of the moisture is left on the Windward Side of the mountains 3 As the dry air descends on the Leeward Side it warms The warm dry air creates a desert climate

Page 29

ii CONVECTION CURRENTS Earth s Convection Currents are continuous cycle of magma rising and falling in the Earth s mantle The movement of magma causes friction between the tectonic plates causing them to move The movement of the plates causes events like volcanic eruptions earthquakes and tsunamis

Page 30

iii THEORY OF PLATE TECHTONICS The Theory of Plate Tectonics came from Alfred Wegener and his Continental Drift hypothesis He believed that all of the continents were once joined together as one also known as Pangaea He proposed that there were 4 pieces of evidence to support his theory

Page 31

1 Continental Jigsaw puzzle Western Africa and Eastern South America fit together like puzzle pieces 2 Matching Fossils Identical fossils of a Mesosaurus were found on South America and Africa 3 Rock Types Structures mountain ranges with similar rock types and layers have been found on separate continents today 4 Paleoclimate layers of glacial deposits from continental glaciers found in southern Africa in South America also in India Australia

Page 32

iv TECTONIC PLATES Tectonic Plates are two sublayers of the earth s crust that move because of Earths convection currents that may cause continental drift earthquakes volcanoes mountains and oceanic trenches

Page 34

v PLATE BOUNDARIES Plate Boundaries are the locations where two tectonic plates interact and a Convergent Divergent or Transform Boundary exists

Page 35

DIVERGENT two or more plates pull away from each other forming Rifts and Mid Ocean Ridges CONVERGENT two plates move toward each other and collide causing uplift TRANSFORM two plates grind past each other causing faults

Page 36

vi FAULTING a Fault is a fractures in the crust along which rocks on one side move past rocks on the other side

Page 37

DIP SLIPS are when two pieces of land change their vertical position compared to each other After the movement one side is higher than the other side NORMAL REVERSE STRIKE SLIP FAULTS happens when two pieces of land move horizontally to each other

Page 74

TOPIC OUTLINE i WHAT ARE EARTHQUAKES ii SEISMIC WAVES iii VOLCANOES DEFINED iv HOT SPOTS v TYPES OF VOLCANOES

Page 75

i WHAT ARE EARTHQUAKES Earthquakes are the result of a sudden release of energy when two tectonic plates rub together also known as Faulting Earthquakes are measured using a Seismograph and based on magnitude of the Richter Scale

Page 76

FOCUS is the exact point where the earthquake started EPICENTER the point on the surface directly above the focus FAULT is a crack in the Earth s crust

Page 77

ii SEISMIC WAVES Seismic Waves are ripples then move out in waves across the plate The two types of Seismic Waves are Primary Waves Secondary Waves P Waves S Waves

Page 78

PRIMARY WAVES P Waves are the first waves to arrive by being able to move fast through solids and liquids SECONDARY WAVES S Waves are slow moving arrive after P Waves and cannot move through liquids

Page 79

iii WHAT ARE VOLCANOES Volcanoes are formed whe n magma from within the Earth s upper mantle escapes to the surface At the surface it erupts to form lava flows and ash deposits Over time as the volcano continues to erupt it will get bigger and bigger

Page 80

Volcanoes Continued A volcano is considered Active if it is erupting or has shown signs that it may erupt in the near future If a volcano has not erupted for a long time but may erupt again one day it is considered a dormant volcano If a volcano has not had an eruption for at least 10 000 years and is not expected to erupt again it is considered Extinct

Page 81

iv HOT SPOTS Hot Spots are areas of volcanic activities that result from plumes of hot solid material that have risen from deep inside Earth s mantle

Page 82

The Ring of Fire is an area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur Hot Spots

Page 83

v TYPES OF VOLCANOES Composite Volcano composed of layers of lava and ash that have explosive and quiet eruptions Cinder Cone Volcano composed of layers of lava and ash that have explosive eruptions Shield Volcano broad volcano with gently sloping sides built by nonexclusive eruptions of basaltic lava that accumulates in layers

WEATHERING EROSION

Page 86

TOPIC OUTLINE i WEATHERING EROSION DEFINED ii CHEMICAL WEATHERING iii MECHANICAL WEATHERING iv RIVER EROSION

Page 87

i WEATHERING EROSION WEATHERING is the process by which natural forces break down rocks The two types of weathering is Chemical and Mechanical EROSION is when weathered particles are picked up and moved from one place to another The three agents of erosion are water wind and ice

Page 88

ii CHEMICAL WEATHERING Chemical Weathering is the breakdown of rock or materials by chemical reactions that changes its chemical composition Factors that effect the rate of chemical weathering is the surface area of rock exposed rock composition and climate Types of Chemical Weathering OXIDATION combining air and water with iron to produce rust ACID RAIN Rain containing sulfuric acid from pollution

Page 89

iii MECHANICAL WEATHERING Mechanical Weathering is the breaking up of rock by physical force Types of Mechanical Weathering ABRASION wearing down rock by friction EXFOLIATION layers of rock gradually break off as pressure is released from the rock ICE WEDGING ROOT PRY the repeated freezing and thawing of water in rocks that causes the rock to split apart breaking apart rocks by plant roots growing in the cracks

Page 90

iv RIVER EROSION Oxbow Lake Formation C B A 4 1 2 3 1 Erosion makes the Neck narrower 2 During Floods the river takes shortest course through the neck 3 Necks connect to form new straight river 4 Oxbow Lake is formed from the deposition sealing the old meander

Page 94

Distribution Of Water 97 of Earth s water is Salt Water while only 3 is fresh water Of that 3 is fresh water 30 1 is Ground Water and 68 7 is Icecaps Glaciers Of the 30 1 of freshwater surface Water 87 is lakes 11 Swamps and 2 Rivers

Page 95

ii WATER CYCLE the Water Cycle is the continuous movement of water between the Earth and its atmosphere 2 1 3 4

Page 96

EVAPORATION 1 2 is vaporization that occurs at the surface of a liquid below the liquid s boiling point CONDENSATION is the change of state from a gas to a liquid PRECIPITATION 3 is rain snow sleet or hail that falls from clouds to the Earth s surface RUNOFF 4 is water that flows across the land and enters rivers and streams It eventually flows into lakes and the ocean

Page 97

iii GROUND WATER TABLE Groundwater is water that infiltrates the soil and is located in underground reservoirs called aquifers Artisan Well Surface Unsaturated zone Water Table Saturation Zone Aquifer

Page 98

Unsaturated zone the area between the surface and aquifer that contains mostly air and a little water water Water Table the boundary where the zone of aeration and the zone of saturation meet Saturation Zone the area in which the pore spaces between soil and rock particles are completely filled with water

Page 99

iv PERMEABILITY Permeability is a rock s ability to let water pass through it A rock can either be Permeable or Impermeable

Page 100

Permeable surfaces allow water to percolate into the soil to filter out pollutants and recharge the water table Impermeable surfaces are solid surfaces that don t allow water to penetrate forcing it to run off PERMEABLE IMPERMEABLE

Page 101

v STREAMS Drainage Systems are the patterns formed by the streams rivers and lakes in a particular drainage depending on the type of land The most common drainage patterns are Dendritic Radial Rectangular and Trellis

Page 102

DENDRITIC develops along the surface of homogeneous horizontal bedrock RADIAL develops around a central elevated point and runs down all sides uniformly RECTANGULAR develops in regions where there is faulting The water takes the path of least resistance and will follow along the breaks in bedrock TRELLIS develops in areas of folded topography The water will mainly flow along the centers of folds but may escape at weak points between folds

Page 103

vi STREAM VELOCITY The velocity of a stream depends on its flow type channel shape gradient and discharge The faster the stream is flowing the larger particles it can carry Stream Velocity is slowest near river bed and banks due to friction
