Answer:
Explanation:
Nuclear fusion occurs in the core of a star. Stars use the process of nuclear fusion to convert hydrogen to helium, and this process provides energy for the star, making the star very hot and bright. When the star runs out of either hydrogen or helium and nuclear fusion in a star's core stops, the star is no longer creating energy. Without energy, the core cools and the outer layers of the star begin to expand and become less bright, and the star will eventually either collapse or explode.
Answer:
Normal fault
Explanation:
Tensional stress occurs as a result of forces which could be wind, water etc pulling the rocks apart and forming faults. Faults are also known as a type of fracture which occurs between rocks.
Tensional stress along a fault can result in a dropped hanging-wall block relative to the footwall side(in a perpendicular position) thereby producing a normal fault.
Passes from body to body until it becomes pure
Main Difference
The key difference between Physical Map and Political Map is that Physical Map indicates the natural features of a place like mountains, waterbodies plains, etc. and The political map shows territorial features like country, cities, nations and their boundaries.
Physical Map vs. Political Map
The difference between a political map and physical map stems from the purpose for which they are created. Before discussing that further, let us first see what a map is. Maps are representations of natural features and landforms on a piece of paper with greatly downscaled ratios. Maps are important as they could be used to locate a place in an unknown area and also used to get directions to reach a particular location. To meet the requirements, different types of maps are available out there. Two important types of maps are the political map and physical map. A physical map is used to show geographic properties of an area such as mountains and rivers, while a political map is one that shows the cities, roads, and borders of different countries. This is the key difference between a political map and physical map, but there are other differences that we will discuss in this article.
