Answer:
The construction and operation of dams in the Colorado River have multiple benefits that include having increased water for irrigation and domestic supply, generation of hydroelectric power energy, providing improved aquatic recreation and wildlife habitat, and flood control. Damming the river has also some drawbacks.
Answer is C it encourages scientific research
Answer:
Extensional faulting observed in southwestern Mexico has been related to the incipient rifting of the Jalisco block from the Mexican mainland since the Pliocene. On the basis of new structural and geophysical data, we propose that (1) the continental boundaries of the Jalisco block are ancient structures reactivated since the Pliocene at a low (<1 mm/yr) rate of deformation, and (2) Pliocene-Quaternary extensional faulting at the edges of Jalisco block is a basement-controlled intraplate deformation related to plate boundary forces rather than to active continental rifting. The Jalisco block boundaries first developed in response to the uplift of the Puerto Vallarta batholith in pre-Neogene time and underwent a complex contractile deformation before the Pliocene. During Pliocene-Quaternary times north-northeast extension reactivated the northern boundary, forming the Tepic-Zacoalco rift, whereas east-southeast extension formed the northern Colima rift. South of the Colima volcano, active extension is found only west of the so-called southern Colima rift and partly reactivates old northeast-trending basement faults. The parallelism between the subducted Rivera-Cocos plate boundary zone and the eastern neotectonic boundary of the Jalisco block supports eastsoutheastward motion of the southern Mexican blocks induced by the differential motion and oblique subduction of the Cocos and Rivera plates. On the other hand, we envisage Pliocene-Quaternary extension along the northern boundary as an upper-plate response to the low convergence rate and the steep subduction angle of the Rivera plate.
Answer:
The main difference between a geyser and a hot spring is that a geyser has an obstruction in its hydrothermal plumbing near the surface but a hot spring is allowed to circulate to the surface and flow freely, giving off steam and heat.
Explanation:
Sum of all angles in a quadrilateral is 360....so x=36
1st angle=4(36)=144
2nd angle=3(36)=108
3rd angle=2(36)=72
4th angle =36
