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.
Coastal areas that are near warm ocean currents are more likely to experience warmer weather.
The Earth is such a magnificent place to live in, with all those skies that change hues throughout the day and all those rivers, lakes , mountains and rock formations that just added to its natural beauty.
The Grand Canyon which is located at the northwest corner of Arizona, is one of the Earth's scenery that was formed through a natural geologic process of weathering and erosion.
Geologic experts say that there is a number of combined processes that attributed to the majestic view of the Grand Canyon, the most powerful of which is erosion, primarily by water and ice, and secondly by wind.
The course of the Colorado River that curved the canyon has also contributed to the formation of the canyon, along with volcanic activities, continental drift and slight variations in the earth's orbit that dictates the variation in season and climate.
