Lava that cools so quickly that the ions do not have time to arrange themselves into crystals with definite shape will form igneous rocks with FINE GRAINED TEXTURE. Igneous rocks are those rocks formed as a result of cooling of magma or lava.
The features that result as a form of a glacier carving out rock and forms into the landscape over which it slides are called cirques. When a glacier moves it erodes the surface of the earth beneath it. In this process of erosion large boulders and very small pebbles all get caught up in the path of the glacier and move along with it. This moment causes deep depressions into the earth, changing the landscape. The deposition of rocks and silt from a melting glacier also changes the form of the land over which the glacier moves.
Africa is the continent that has the most countries through which the Equator passes. In fact, 7 out of the 13 countries in the world through which the Equator passes are in Africa. From west to east they are in this order, Sao Tome and Principe, Gabon, Republic of the Congo, Democratic Republic of the Congo, Uganda, Kenya, and Somalia. The Equator is an imaginary line invented by the humans for their own purposes. It basically is the line that separates the Earth into two equal parts horizontally, or rather into Northern Hemisphere and Southern Hemisphere. The Equator has latitude of 0 degrees, and it is the starting point from which the latitude is measured both north and south. This part of Africa is characterized with warm and wet climate, with the temperatures being constant throughout the whole year and have only few degrees of change, resulting in constant summer. The landscape is covered with dense tropical vegetation, and there's enormous amount of species that live in this area.
