= **Convergent Boundaries are when __tectonic plates__ coiled**. = **They can form;**
 * 1) **Mountains**
 * 2) **Volcano**
 * 3) **Islands**

= **Continental vs. Continental** = = = = Continental vs. Ocean = = = =** Ocean vs. Ocean **=
 * **When two continental plates collide, they form mountains such as, The Himalayas.**
 * **It also creates volcanoes such as, Guadalupe.**
 * **Island such as the Hawaiian Islands have formed.**

 * ** When a continental and ocean plate collide. **
 * ** The ocean (the weaker) plate goes under the continental (stronger) plate and creates a subduction zone, and can create volcanoes **
 * ** Subduction in Cont. vs. Ocean is when the cont. plate laps over top of the ocean plate. It forms a subduction zone. **

 * ** When the oceanic plates divide, and new plates take their place. Making them move farther across the ocean with every new plate. **
 * ** These can form Trenches and Sea-Floor Spreading. **
 * ** You will find this along the Mid-Ocean Ridge. **
 * ** Subduction isnt just in ocean vs. cont., it's in ocean vs. ocean too! It's when one of the oceanic plates over laps the other. This forms a trench. **
