Whether you were struggling last year or not, becoming an "A" student or maintaining an "A" average is a goal that every student should have. Grades are very important, but even more, so is understanding the concepts. Here are some ways to become an "A" student this school year. Organizational Skills Being organized is an essential skill to have if you want to be an "A" student. This means you have to become very familiar with to-do lists and planners. Have a folder with sections for each subjec t that you do so that you can easily and effectively file handouts, worksheets, notes and test papers. Studying : As it relates to studying, create a list with the topics or points that you wish to study based on the time that you have to study. However, be realistic with what you can achieve in each study session. There are also various study techniques that you can make use of! Homework : When it comes to homework, be sure to create a list of your h...
Convergent plate boundaries 
Convergent plate boundaries are also called destructive plate boundaries. At this boundary, plates collide causing earthquakes, volcanic activity and folding. As the plates push towards each other, it causes the rocks to crumble and fold. Some rocks fold downwards and some fold upwards forming very high mountains.
Where oceanic crust collide with continental crust, the denser oceanic crust is pushed under the less dense continental crust. This process is known as subduction and where it happens is known as a subduction zone. As the oceanic crust is pushed below the continental crust, massive forces are generated. This causes the edge of the oceanic and continental plates to bend forming a V shaped depression called an ocean trench. The oceanic crust melts as it is pushed down into the mantle. This molten material may rise through weaknesses in the crust forming volcanoes near the plate boundary.
There are instances where oceanic crust collides with oceanic crust. In this case, one of the oceanic plates will be pushed under the other forming a subduction zone and creating an ocean trench. As the plate is pushed down into the mantle it melts. Molten material may rise through weaknesses in the crust forming underwater volcanoes. These volcanoes may eventually grow tall enough to rise above the surface, forming volcanic islands. A chain of islands known as an island arc may form in this way. The Lesser Antilles is a good example of an island arc. This arc formed as the crust beneath the western edge of the Atlantic ocean was forced. below the edge of the Caribbean plate. There are still active or dormant volcanoes on many of the islands in this arc.
If two continental plates collide, it creates a collision zone that leads to very high mountain ranges.
