The sun is in the highest point in the sky. The northern end of Earths axis is tilted toward the sun. The Northern hemisphere receives minimal daylight.
Surface of the Earth: Most of the Earth's surface (70%) is covered with water, and the remaining 30% is taken up by the seven continental landmasses. However, underneath the water that fills the oceans, and the dirt and plants that cover the continents, the Earth's surface layer is made of rock.
A large volume of air that has nearly the same temperature and humidity at different locations at the same altitude is called the Air Mass. Air mass covers hundreds or thousands of square miles and adapt to the characteristics of the surface below them at the same time they are also classified according to latitude and their continental or maritime source regions.
