C. Sandstone and Basalt make a metamorphic rock.
Answer:
Option (B)
Explanation:
The Maurya Empire was one of the famous and largest empire in India in its historical time. It was originated by Chandragupta Maurya, the person who had dethrown the Nanda Dynasty. He was very powerful and expanded his territory in almost all parts of India. This empire was remarkable for the regular and successful administrative system and also the finance system that eventually lead to the production and development of its economy.
The Maurya empire was bordered by the great mountains of Himalaya on its northern side.
Thus, the correct answer is option (B).
Answer:
“Crust” describes the outermost shell of a terrestrial planet. Our planet’s thin, 40-kilometer (25-mile) deep crust—just 1% of Earth’s mass—contains all known life in the universe.
Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. At the center of the Earth is a hot, dense metal core.
Earth’s layers constantly interact with each other, and the crust and upper portion of the mantle are part of a single geologic unit called the lithosphere. The lithosphere’s depth varies, and the Mohorovicic discontinuity (the Moho)—the boundary between the mantle and crust—does not exist at a uniform depth. Isostasy describes the physical, chemical, and mechanical differences between the mantle and crust that allow the crust to “float” on the more malleable mantle. Not all regions of Earth are balanced in isostatic equilibrium. Isostatic equilibrium depends on the density and thickness of the crust, and the dynamic forces at work in the mantle.
Just as the depth of the crust varies, so does its temperature. The upper crust withstands the ambient temperature of the atmosphere or ocean—hot in arid deserts and freezing in ocean trenches. Near the Moho, the temperature of the crust ranges from 200° Celsius (392° Fahrenheit) to 400° Celsius (752° Fahrenheit).
The Yucatan Peninsula and the Baja California Peninsula are two peninsulas found in Mexico.
