Let us start arbitrarily by beginning the drawing of the 1020-mb isobar in nebraska. north platte, ne would be on a 1020-isobar line generally running north-south. three other isobar lines are noted or needed through the eastern part of the state, given the 4-millibar interval convention. these three lines will separate values where the lower value on the map remains to one side while higher values are on the other side. the pressure values of locations generally east of north platte are therefore 1020 mb.

The correct answer is a.

The reason why i feel that the theory of plate tectonics is correct because scientists have found dinosaur bones of the same species in africa, asia, and in the americas. which means that they must have been together at one point in time. plate tectonics is also how the hawaiian islands were formed. as the plate hawaii is on was moving north west, magma would melt through the sea bottom and hardening. forming into the island chain. plate tectonics also explains the mariana trench. two plates were moving away from each other and made a giant crack in the ocean floor running 2,550 kilometers (1,500 miles)  long.

Aeolian processes,  pertain to  wind  activity in the study of  geology  and  weather  and specifically to the wind's ability to shape the surface of the  earth  (or other  planets). winds may  erode, transport, and deposit materials and are effective agents in regions with sparse  vegetation, a lack of soil moisture and a large supply of unconsolidated  sediments. although water is a much more powerful eroding force than wind, aeolian processes are important in arid environments such as  deserts
