| Question | Answer |
|---|---|
| Land Forms What is a land form? | A land form is any unique physical irregularity of the earth's surface. |
| Natural Features/Landforms | Unique irregularities in the earth's surface that are normal. Eg. valleys,plains,hills,beaches,wetland etc. |
| Natural Phenomena | Atmospheric conditions that can be observed and also occur naturally. Eg. clouds,rain,wind,evaporation,snow etc. |
| Land form creation Tectonic Forces. | Leads to the formation of land form by large scale movements in the earth's surface.This causes mountains and valleys to be formed. |
| Denudation | Leads to the formation of land by altering the shape of the land. Coastal cliffs and rivers are formed by denudation. |
| Deposition | Leads to the formation of land form from the material on the surface of the land.Which can form a delta from the sediment carried down by the river. |
| Some land form features. | Island,Peninsula,Cape,Point,Bay,Strait,Beach,Plain,Mountain,Hill,Valley,Swamp,Archipelago,Continent,Ocean,Sea,Lake,Gulf and Isthmus. |
| What is air pressure? | Air pressure is the atmosphere that surrounds the earth is a layer of air made up of a mixture of gases.The air is heavy and presses down on the earth. |
| Water Cycle | The interchange of water between the atmosphere, the land and the ocean. |
| The Distribution Of Water | 97.6%-ocean 1.9%-glaciers 0.5%-ground 0.02%-surface storage 0.0001%-atmosphere |
| The Processes within the water cycle | Accumulation Evaporation Condensation Precipitation Transpiration Surface runoff Sub surface runoff |
| The Processes in the water cycle | [Input]-condensation and precipitation [Transfers]-surface runoff,infiltration,through flow and advection. [Outputs]-transpiration and evaporation [Storage]-underground,swamps,rivers,lakes,ponds,oceans and seas and glaciers. |
| Rivers | A River is a network of channels that carry fresh water from a high point such as a mountain to a low point such as a sea. |
| Parts of the river | Source,Stream,Waterfall,Meander,Tributary,Confluence,Floodplain,Estuary,Mouth,Drainage Basin and Water shed |
| Transportation of The river | Rivers pick up and carry material as they flow down stream. A river may transport material in four different ways:Solution,Suspension,Saltation and Traction. |
| River features | [Upper Course]- Narrow V shaped valleys,Interlocking spurs,Rapids,Waterfalls,Gorges. [Middle Course]-Meanders,River Cliffs and Slip-off Slopes. [Lower Course]-Deltas,Leves,Flood plains. |
| Natural Hazards | Is any event that could cause injury or death to others. |
| Some natural hazards | Hurricanes,Tsunami,Volcanoes,Earthquakes,Flooding etc. |
| What is a hurricane? | A hurricane are tropical cyclones that are strong low pressure cells that spend most of their lives over the oceans. |
