QUESTION 2 What major U.S. river originates in the Colorado Rockies and created a large delta at the northern end of the Gulf of California? QUESTION 3 I the material carried by the river in Question 2 had not been deposited, the Gulf of Calfomis would extend northward to include the inland sea shown in this satelite image. What is the name of Mexico this inland sea?Explanation / Answer
1) GULF OF CALIFORNIA: The gulf of california is located along a divergent plate boundary, where heated subsurface material wells up, cools and is added to the edges of the plates which move away from each other on opposite sides of a spreading center. as part of the pacific pleate, baja california will eventually be pulled away from the mainland as the gulf of california extends northward. the east pacific rise lies near the eastern portion of the pacific ocean and seperates the pacific pleate from the nazca and cocos plates. it extends in to the gulf and is evidenced on land as a series of transform faults of which the san andreas fault is a major compnent. the rise reappears in the pacific ocean just north of cape mendocion in northern california. the san andreas fault system is an enormus shear zone generally referred to as a right lateral strike-slip fault earth movement along the fault is caused by spreading beneath the east pacific rise. the southern point of the fault, is marked by a triple junction that migrates south as subduction of the rise system continues. the great california and recent mexican earth quuakes and mexican volcanoes are a result of this tectonic activity.
2) The colorado river is one of the principal rivers of the southern western united states and nothern mexico the 1,4250 mile lonng river drains an expansive arid watershed that encompasses parts of seven us and two mexican states starting in the central rocky mountains in the us the river flows generally south west across the clolorado plateau and through the grand canyon before reacing lake mead on the arizona nevada border where it turns south toward the internation border. after entering mexico the colorado approaches the mostly dry coloraod river delta tat the tip of gulf of california between baja califfornia and sonora..
3) The New Inland Sea in the satellite image is callled Alamo River
