1. “boundaries” tab

in the “interactive key” box, click the convergent, divergent and transform buttons to show their locations on the map. answer the questions below

1. convergent boundaries

a. describe how the plates are moving in a convergent boundary
b. where on the map are convergent boundaries?

1. divergent boundaries

a. describe how the plates are moving in a divergent boundary
b. where on the map are divergent boundaries?

1. transform boundaries

a. describe how the plates are moving in a transform boundary
b. where on the map are transform boundaries?

Explanation:

1. Convergent Boundaries:

• a. Plates move towards each other. One plate may be sub - ducted under the other.
• b. Convergent boundaries are often found at the edges of continents where oceanic plates meet continental plates (e.g., the Andes where the Nazca plate subducts under the South American plate), or where two oceanic plates collide (forming island arcs like the Japanese islands).

1. Divergent Boundaries:

• a. Plates move away from each other. Magma rises to fill the gap, creating new crust.
• b. Divergent boundaries are typically found in the middle of oceans, such as the Mid - Atlantic Ridge, where new oceanic crust is being formed.

1. Transform Boundaries:

• a. Plates slide past each other horizontally.
• b. Transform boundaries can be found on the ocean floor (e.g., the fracture zones in the Atlantic Ocean) and on land (e.g., the San Andreas Fault in California).

Answer:

1.

• a. Plates move towards each other.
• b. At edges of continents where oceanic and continental plates meet or where two oceanic plates collide.

2.

• a. Plates move away from each other.
• b. In the middle of oceans like the Mid - Atlantic Ridge.

3.

• a. Plates slide past each other horizontally.
• b. On ocean floor and on land (e.g., San Andreas Fault).
