A coast landform is very easy to explain. All it is a land that is connected to. a sea or a ocean. The United States has around 95,000 miles of coastline. This fact was taken from the NOAA. There are many more miles of coast around the world.The CIA also gives many other facts about how many miles of coast we have around the world. sea or a ocean.

Dimension. The dimension of an object is a topological measure of the size of its covering properties. Roughly speaking, it is the number of coordinates needed to specify a point on the object. For example, a rectangle is two-dimensional, while a cube is three-dimensional.
Being a vector, (x, y) has a a certain distance (magnitude) from and angle (direction) relative to the origin (0, 0). Vectors are quite useful in simplifying problems from three-dimensional geometry. Definition:A scalar, generally speaking, is another name for real number. Definition: A vector of dimension n is an ordered collection of n elements, which are called components. Notation: We often represent a vector by some letter, just as we use a letter to denote a scalar (real number) in algebra.
