 * Questions 1.- **
 * Convergent: ** To converge is to come together from different directions.
 * Divergent: ** A line or surface that draws apart from another line or surface.


 * Question 2.- **
 * The **lithosphere is created** at **divergent** boundaries, which are the boundaries between two plates that are **moving away** from each other. **Rifts** form here and through these gaps **molten material from the mantle often rises up to the surface, solidifies and forms new lithosphere (plates grow in size).**
 * ** Part of the lithosphere is destroyed at convergent boundaries, ** which are the boundariesbetween two plates that are **moving towards each other. One of the plates moves under the other and sinks inside the mantle, destroying part of the lithosphere (one plate reduces in size). There is usually a trench along these boundaries**


 * Question 3.- **
 * Plate boundary interaction generates huge forces, friction and an increase in the temperature of the lithosphere. These produce geological processes, such as volcanoes, earthquakes and mountain ranges. **


 * Question 4. The theory states that the Earth´s lithosphere is broken up into plates, which are dynamic and that the interactions between their boundaries produce geological phenomena. **
