Answers
Answer:
1. The structure of the earth is divided into four major components: the crust, the mantle, the outer core, and the inner core. Each layer has a unique chemical composition, physical state, and can impact life on Earth's surface...
2. THE MANTLE IS ONE OF THE THREE MAIN LAYERS OF THE EARTH.IT LIES BETWEEN THE INNERMOST LAYER, THE CORE AND THE THIN OUTERMOST LAYER , CRUST. THE MANTLE CONSISTS OF HOT,DENSE SEMISOLID ROCK AND IS ABOUT 2,900 KILOMETERS(1,800 MILES) THICK. MOVEMENT IN MANTLE CAUSES VOLCANIC ERUPTIONS AND EARTHQUAKES...
3. Sedimentary rocks are largely found on the Earth's surface. They cover 75% area of the Earth. These rocks are generally not crystalline in nature. They are soft and have many layers as they are formed due to the deposition of sediments...
4. The rock cycle is a process in which rocks are continuously transformed between the three rock types igneous, sedimentary and metamorphic. ... If the sediments are buried under further layers of sediment, they can become lithified to produce a sedimentary rock. Magma is produced when rocks are melted...
5. We cannot go to the centre of the earth. Answer: Since the temperature and pressure increase enormously as we go deeper and deeper inside the earth, we cannot go to the centre of the earth. ... Answer: Because of extreme heat and pressure, limestone undergoes a change in its form and turns into marble...
6. It is impossible to reach the centre of the Earth because the temperature increases with the increase in depth. ... So it is impossible to access direct information about the Earth...
This is the hope it's helpful for you...
