Answer:
Rift valley, fault, graben and mid oceanic ridge are the landform formed due to divergent plate boundary.
Explanation:
Plate boundary explains convergent or destructive, divergent or constructive and transform plate boundary across the world between different plates. African rift valley formed in the Africn continent which is major landform due to divergent plate boundary. Faault and graben also formed which means narrower than rift valley. Mid oceanic ridge formed in North Atlantic ocean which is formed between North American plate and Eurasian plate due to divergent plate boundary.
The circle has two forms of equation - General Form and Standard Form. The general form of the equation of the circle would be x^2 + y^2 + Dx + Ey + F = 0. The constants of this equation are D , E and F. The way to use general form is to complete the square and then proceed the equation in standard form. In that way we can identify the radius and center of the given circle.
