What is the Mohorovicic discontinuity made of?

As you probably know, the Mohorovicic Discontinuity is the boundary of the earth’s crust and the mantle. It would be made of elements such as oxygen, iron, sodium, silicon, and aluminum, among others. These elements would be present in rocks that make up both the Earth’s crust and mantle. What is the composition of Mohorovicic

What happens during a mudslide?

Mudslides develop when water rapidly accumulates in the ground and results in a surge of water-saturated rock, earth, and debris. Mudslides usually start on steep slopes and can be activated by natural disasters. What happens in mudslides? Quote from video:And lives mudslides are what site is called debris flows.

Is classification of fine grained soil? fine-grained soil can be classified as silty soil with intermediate plasticity to

What was the atmosphere like during the Paleogene period?

During the Paleogene period, most of the Earth’s climate was tropical. The Neogene period saw a drastic cooling, which continued into the Pleistocene epoch of the Quaternary period. As for the changing landscape, the continents drifted apart during the Paleogene period, creating vast stretches of oceans. What was the temperature like during the Paleogene period?

What is mineral and types?

What subdivision of the geologic time scale represents the greatest expanse of time?

There is another kind of time division used – the “eon”. The entire interval of the existence of visible life is called the Phanerozoic eon. The great Precambrian expanse of time is divided into the Proterozoic, Archean, and Hadean eons in order of increasing age. What subdivision of the geologic time scale represents the largest
