Answer:
If the two plates are of equal density, they usually push up against each other, forming a mountain chain. If they are of unequal density, one plate usually sinks beneath the other in a subduction zone.
Explanation:
Convergent boundaries is where two plates (a continental plate and the ocean floor) get "pushed together" by subduction. If they have the same density, they will be pushed up together creating a mountain (the Himalaya's mountain is a great example). If the plates have different density then the one with more density overlaps the other.
When General Grant took command, the Union Army was still exchanging prisoners of war. This allowed each side to return their men to their country to fight again. Grant knew that the Union had more men and could produce more weapons than the Confederate. So he ended the prisoner exchange. This of course resulted in more men held in prisoner of war camps and creating problems for both sides, resulting in many deaths in these camps---both in the North and in the South. Grant also pressed his troops to stay on the attack. In some battles, his casualties were very high but he still knew that the Confederates could not replace their losses as easily as the Union could. Grant used General Sherman to force the war onto the civilian population and the industrial centers of the Confederacy. This was a new concept to most commanders. War was a duel between armies on the field of battle. The destruction of the industrial sites prevented an enemy from arming his troops and conducting war.

</span><span>AD 900-1400 - Farming and hunting people from this time in Oklahoma prehistory settled along major rivers and creeks. They planted corn, beans and squash in the fertile flood plains, hunted bison and deer, and fished and gathered mussels from the rivers. Four of these cultures have been defined in western and southern Oklahoma. Since we have no written records from this time, the names of these cultures are unknown. When early Spanish explorers came in the 1500's, they found people who called themselves the Teyas and the Escanjaques. Perhaps the people discussed here also used these names several hundred years earlier. Archeologists believe the Teyas and Escanjaques are descendants of the people discussed on these pages. They are all believed to have been Caddoan speakers.

Their general performance early war was poor, due to them not being a real army, but rather more like quickly formed militia, consisting of untrained personnel. In all early battles there were outnumbered, and had little to no time to organize effective battle units. It was General Washington that managed to organize the militias into a regular army.
