Physical Models:

Scientists attempt to understand the world by acquiring ideas that correspond with reality as closely as possible. Geologists have traditionally modeled the surface and subsurface of the Earth using one or more physical dimensions. These are length, width, depth, and time. Most of these geological models would be considered maps.link to an Internet Website

Earth's surface features are located by their latitude and longitude. link to an Internet Website

The equator is 0 degrees latitude.

  • Latitude - describes north or south of the equator.
    • The equator is 0o latitude.
    • Lines of latitude circle the earth, never meeting. For this reason they are called parallels.

  • Longitude - describes east or west of the prime meridian.
    • Each line of longitude runs halfway around the earth, from the North Pole to the South Pole.
    • Lines of longitude are called meridians.
    • Meridians are spaced farthest apart at the equator and converge to a point at the poles.
    • The prime meridian, link to an Internet Website indicating 0o longitude, was defined in 1884 as passing through the Royal Observatory, in Greenwich, England.
    • The international dateline link to an Internet Website is 180o from the prime meridian.

Phoenix Arizona is located at 33o 22' 30" North and 112o 00' 00" West.

Terrestrial biomes  link to an Internet Website are described the by their average rainfall, temperature, and major plants and animals. Because environmental factors change gradually over a landscape, biomes seldom have distinct boundaries. As climate varies, one biome gradually changes into another. Scientists do not even agree on the number of terrestrial biomes represented on Earth. Even most textbooks lists different numbers of  "major" biomes and their characteristics. Here are links to one system of biomes:

Arizona has a wide range of conditions as you move across the state. The general topography of the state slopes downward from the northeastern Colorado plateau to the southern and southwest deserts of the state only to be interrupted by the central mountains cutting across the state from the northwest to the southeast. The Colorado river has cut the Grand Canyon in the North and Northeastern portion of the state. The highest elevation, 12,633 feet above sea level is located at Humphrey's Peak, while the lowest elevation is 70 feet above sea level at the Colorado river. Phoenix, AZ is at an elevation of about 1,200 feet above sea level. Normal yearly precipitation link to a local picture and mean temperature link to a local picture vary greatly across the state. Arizona is divided into these different geographic regions. link to a local picture

Aquatic biomes are described by the characteristics of the water, and the major plants and animals present.

Almost three quarters of the Earth's surface
is covered by seven seas. link to a local picture

Ocean water contains about 3% salt, which greatly affects the biology of the organisms that live there. Since water absorbs light, sunlight penetrates only the upper few hundred meters of the ocean, greatly affecting ocean life. Oceans are also very important in regulating the temperature on Earth. The Gulf Stream link to a local picture is one of several ocean currents the distribute heat.

Phoenix, Az is about 1,250 feet above sea-level.

 

 

 

 

 

 

 

   

 

None. All rivers in Arizona flow from north and east to south and west.

 

 

 

 

 

 

 

   

 

In warm weather, the coolest water in a pond or lake is at the bottom, while in cold weather, the water is coolest at the top. A body of water is said to "turn over" when the cold water and warm water switch places with the change of season.
