First the Amazon River, it begins in the Andes Mountains as a little river called the Apurima River. It flows about 4,000 miles(6,400) kilometers, and spills out into the Atlantic Ocean. Before that it runs through many countries. Venezuela, Equador, Colombia, Bolivia, and Brazil. Although the largest portion is in Brazil.

In the Amazon the season is always rainy. January through April are the wettest season, while June through November are the dry months. Most tributaries begin flooding in November and may continue to rise until June. Not all tributaries flood at one time. The Medeira rises and falls two months earlier than most of the rest of the Amazon. The Amazon is a tropical region with a lot of rain and humidity. The temperature usually comes to 26 degrees Celsius, and at night it drops to about 10 degrees Celsius. The amount of precipitation that falls each year is about 274 cm.

The Tanana is located in Interior Alaska about two miles west of the junction of the Tanana and Yukon Rivers west of Fairbanks. The community lies at approximately 65.171940° North Latitude and -152.078890° West Longitude.
Tanana is located in the Ft. Gibbon Recording District.

The area encompasses 11.6 sq. miles of land and 4.0 sq. miles of water. Tanana experiences a cold, continental climate with temperature extremes. Daily maximum temperatures during July range from 17 to 21 °C; daily minimum temperatures during January are -25 to -44 °C. Extremes have been measured from -57 to 34 °C. Average annual precipitation is 33.02 cenimeters, with 127 centimeters of snowfall. The river is ice-free from mid-May through mid-October.The difference between these to rivers, The Tanana River, and The Amazon River, is their climates. The Tanana River's climate is colder between seasons because it is farther away from the equator. The Amazon River is warm a lot of the time because it is very close to the equator, only a little farther south.
