Unit 1 test study guide Climate What is the most important factor determining the climate of a region? latitude (1) Delta ______ are common landforms created by rivers flowing into a larger body of water as the river waters meet the tide of the larger bodies of water. Deltas (2) An underwater earthquake along a subduction zone can cause this: (3) Tsunami Climate -Temperature ranges in areas located near oceans do not vary much because water heats and cools more slowly. -Temperature ranges in-land, far away from the influence of water temperatures will vary more. (continentality) (4) Subsistence farming (5) Subsistence agriculture is self- sufficiency farming in which farmers grow only enough food to feed their families. In more developed areas, the building of dams have helped improve farming and a better way of life by providing electricity and a reservoir for irrigation. (6) Climate is the weather conditions of a particular location over a long period of time As with polar bears, other bears such as black bears, thrive better in the higher latitudes. 2/16/2016 Answer to the question (7) A human modification of the environment means that humans have actually changed some part of the physical environment. (building dams, canals, roads, etc.) Human adaptation to the environment is a change in human behavior to cope with environmental conditions. (wearing heavy clothes in the winter or cold climates, wearing light clothes in summer or warm climates, heating homes, air-conditioning & insulation in homes, & preparing for a hurricane, etc.) When does a hemisphere have a warm climate? When it is tilted towards the sun Sun Earth Relation (8) Physical maps (9) Vegetation maps are physical maps that show a regions physical characteristics, such as vegetation. They also will show man made features as well. Region 10. States in the same region will have the same physical charteristics of : Climate, Elevation and Landforms (11) To give the relative location of a place, you would give the directions to the place in relation to the places surrounding it. For example, if I said, "My house is near the school," that's a relative location. I'm telling you where my house is located relative to the school. Absolute location 12 Latitude/Longitude List two factor that change landforms Chemical Weathering This is caused by chemical reactions as a result of interactions between elements in the air or water and the minerals in the rock (water and substances dissolved in it) rather than by mechanical processes. ( 13) Mechanical weathering is the physical that change the characteristics of rock on or near the earths surface, occurring slowly over many years. 13 Go on to section 2
