Question

chaping the land
a group of scientists has been investigating the effects of colliding plate actions. activity along a long seam.
which type of landform is the group researching?
ocean trench earthquake zone ocean ridge mountain range

Explanation:

Ocean ridges are formed by divergent plate boundaries where tectonic plates move apart. As magma rises to fill the gap, it cools and forms new oceanic crust. This process is related to cooling plate activity along a long seam. Ocean trenches are formed by convergent boundaries (subduction), earthquake zones are areas prone to earthquakes (not directly formed by cooling along a seam like ridges), and mountain ranges can be formed by various processes (e.g., convergent boundaries - collision) not specifically by cooling along a long seam as described for ridges.

Answer:

ocean ridge
