This is a divergent boundary.
This is a divergent boundary.
Rift valleys are common at this type of boundary.
Rift valleys are common at this type of boundary.
This type of boundary can form an oceanic trench.
This type of boundary can form an oceanic trench.
Subduction is occurring at this plate boundary.
Subduction is occurring at this plate boundary.
Convection currents within the mantle are moving the plates.

Answer 1

Based on the knowledge of tectonic plates and boundaries, the following statements are TRUE:

1. Rift valleys are common at this type of boundary. (True for divergent boundaries)
2. Convection currents within the mantle are moving the plates. (True, as convection currents drive plate tectonics)

The other statements related to divergent boundaries forming oceanic trenches and subduction occurring at these boundaries are FALSE. Oceanic trenches are typically associated with convergent boundaries, and subduction occurs where one plate is forced under another, which is not the case at divergent boundaries.

So, the TRUE statements are:

- Rift valleys are common at this type of boundary.
- Convection currents within the mantle are moving the plates.
