External Forces and Climate Zones
External Forces • Forces that occur above ground • Erosion, Sedimentation, Glaciation
Erosion • The process by which water or wind removes earth from a region • Can cause huge agricultural problems as farmers lose their land to erosion
Erosion • Along oceans and rivers, can result in loss of property and arable land
Sedimentation • The process in which large amounts of soil gets deposited (put) in one place by a body of water • Happens often at the mouth of large rivers • Creates alluvial plains (good for agriculture)
The last ice age, 10, 000 years ago
Glaciation • When glaciers modify the earth • Then, when the glaciers recede, the changed land is visible • Often makes holes, that become lakes or valleys • Fjords in Scandinavia
What effects precipitation (rainfall)? • Physical barriers— Mountains can block rainfall • Nearness to water —The closer to water, the higher the rainfall and the humidity (even lakes)
Review 1. What is one positive influence of sedimentation? 2. What is one negative effect of erosion? 3. How has glaciation changed the earth’s landscape?
Practice! • Everybody pair will get a white board and a marker. • For every image, you will write: – What earth process is represented? • erosion, sedimentation, pr glaciation. • DON’T DESTROY MY MARKERS! • DON’T DRAW ON MY BOARDS!
Climate and Vegetation
CLIMATE REGIONS
Climate vs. Weather • Climate: The long term environmental conditions in an area. • Weather: The current conditions in an area
Climograph
Ice Cap Very cold all year with permanent ice and snow
Tundra Very cold winters, cold summers, and little rain or snow
A little warmer than arctic, (lower latitude) a little more rain in the summer Subarctic
Marine West Coast Warm summers, cool winters, and lots of rainfall year
Humid Subtropical • Hot, rainy summers and mild winters with some rain • Most common climate in the U. S.
Mixed Forest • A mix of large trees (coniferous and deciduous) • Found in middle latitudes, generally receive above average rainfall
Temperate Grassland • Short and tall grasses adapted to warm summers and cold winters • Generally found in semi-arid climates
Mediterranean • Warm all year with dry summers and short, rainy winters • Considered a mild or temperate climate • Common on the Mediterranean Sea • Because of its unique climate, specialty crops are grown: grapes (wine), figs, dates
Semiarid Hot, dry summers and cool, dry winters
Arid Hot and dry all year with very little rain
Tropical Wet • Hot and rainy all year • Near the equator
Highlands • Mountainous areas • Temperature and precipitation vary with latitude and elevation
Tropical Wet and Dry • Hot all year with rainy and dry seasons • Monsoons—season winds that bring huge amounts of precipitation
Warm up! • Take out your note packet from last class on climate regions. With the person sitting next to you, try to come up with the BEST EXAMPLE POSSIBLE of human-environment interaction for each climate zone. • You have 10 minutes. • While you are doing this, I will pass back your test scores.
Some observations from your FRQ’s • Bad— “One example of human environment interaction is Alaska. ” • Good--Almost everyone labeled their sections • Bad—Trying to get two points in one section • Good—Nobody left blanks • Bad— “Human environment interaction is when humans interact with their environment, ” or “One example of human environment interaction is pollution. ” Too vague, BE SPECIFIC!!! • Suggestion—Make some quick notes on your paper, then pick your best answer
VEGETATION REGIONS • Similar to climate regions, but address the plant life that grows in different climate regions
Practice! • I will put examples of different climate regions up, and you will tell me which it is.
