Chapter 3 Homework Assignment

Chapter 3 section 1
  1. I believe Earth's position in relation to the sun affects temperatures on earth because it varies how much sunlight a particular region receives. This variation of sunlight causes the earth to have seasons of which temperature changes.
  2. Global warming may affect Earth's land, water and air in the following ways: 1) water in the oceans and seas will begin to evaporate to fast, 2)air will contain too much carbon dioxide and heat, and 3) our lands will too dry of soil to grow crops.

I disagree. I believe we can lower the severity of the affects of global warming. We can lower the affects by using electric cars, riding bikes, less fossil fuel efficient factories, and more biodegradable products. If we all try to do these things we will reduce the amount of pollution in the air we breathe and reduce the excess amount of heat trapped in our atmosphere.

Chapter 3 section 2

  1. Latitude and elevation affect the climate of a particular region or area by the "zones" of latitudes. These "zones" of latitude consist of: "high" latitudes, "low" latitudes, "mid"latitudes, the arctic circle, and the antarctic Circle. In the "high" latitudes the regions receive continuous but indirect light. The low latitudes receive direct sunlight year-round making the regions weather "warmer to extremely hot". The low latitudes consist of The Tropic of Cancer, the Tropic of Capricorn, and the equator. Elevation affects the climate because of its relationship between the temperature and elevation at all latitude lines of the regions.
  2. Wind patterns, ocean currents, and landforms play the roles of distributing the sun's energy and heat throughout the planet. For instance, the Earth's ocean currents change the air pressure and the temperatures of its water in particular regions.

If the current by the name of the "North Atlantic Current" became weakened or shut down permanently the Western shores of Europe would have the consequences to their regional climate: Extremely cold temperatures causing a mini ice-age climate, less warm waters causing the flow of water to decrease and maybe causing Greenland to fall or sink to the ocean floor!

Chapter 3 Section 3

  1. Geographers classify the climate regions of the world by the following factors: 1) Winds 2) Air Pressure 3) Characteristics of soil 4) Natural Vegetation. For Example, there are five types of climates: dry, tropical, high-latitude, highlands, and mid-latitude.
  2. Reoccurring phenomena influence climate patterns over time by altering the weather pattern(s). A famous or well-known reoccurring phenomena is called the El Niño it does not always reoccur every year, but most frequently over time. El Niño is a reoccurring phenomena that is an oscillation (or slight changes) of the ocean-atmosphere system in the tropical Pacific having important consequences for the weather around the world.

***In simpler terms El Niño is a periodic change of our earth's ocean currents, water temperatures, and weather in the mid-pacific regions.***

Huntington Beach, California has a Mediterranean climate, sunny and warm almost year-round. We have mild weather conditions, not to rainy or snowy, just colder in the winter. The Natural Vegetation of Huntington Beach consists of Eucalyptus Trees, marshes & wetlands, and several other native plants/flowers. In Huntington beach, our soil is rich and full of nutrients.
