At a __ , tectonic plates push apart from one another as magma rises upward to the surface. transform boundary convergent boundary subduction fault C divergent boundary

## Step 1<br />The problem describes a geological process where tectonic plates push apart from each other and magma rises to the surface. This process is characteristic of a specific type of plate boundary.<br /><br />## Step 2<br />We need to identify the type of plate boundary that matches this description. The options provided are transform boundary, convergent boundary, subduction fault, and divergent boundary.<br /><br />## Step 3<br />A transform boundary is where two plates slide past each other. This does not match the description given in the problem.<br /><br />## Step 4<br />A convergent boundary is where two plates move towards each other. This also does not match the description given in the problem.<br /><br />## Step 5<br />A subduction fault is a type of convergent boundary where one plate is forced under another. This also does not match the description given in the problem.<br /><br />## Step 6<br />A divergent boundary is where two plates move away from each other, allowing magma to rise and create new crust. This matches the description given in the problem.
