The leaves of this plant contain a thick gel that is quite bitter, but contains a protein that has 18 of the 20 amino acids found in the body, as well as Vitamins A, B, C and E and a complex carbohydrate known as acemannan that delivers nutrition to cells and detoxifies them.

This gel can be applied to skin to moisturise it, exfoliate it and prevent acne. It can also be applied topically to injuries, minor cuts, dry skin and severe burns. Applying it to one's hair and scalp prevents itching and dandruff and reduces hair fall. Drinking the juice (mixed with some other fruit juice, since it’s too bitter by itself) treats constipation and acidity, and improves blood sugar levels. Drinking the juice regularly also promotes weight loss.

Which list identifies the order of events that formed a volcanic crater?
A) CBDA
B) BACD
C) CADB
D) DBAC

Answers

The correct answer is C)

Based on the given image, the order of events that formed a volcanic crater is CADB. Thus the correct option is C.

What is a volcanic crater?

A nearly circular hole in the ground produced on by volcanic eruptions is known as a volcanic crater. It is a valley that typically stands just above the eruption where volcanic debris is emitted, and it has the shape of a bowl or funnel.

During volcanoes, craters' dimensions and shapes could alter. A volcanic crater, also known as a caldera, is a sizable depression created when a natural disaster occurs and then collapses.

Underneath the surface of the Earth, the molten rock is known as magma. Less dense than normal lava is being pushed upward to the surface by intense pressure. When magma seeps through layers of preexisting rock, it forms another structure.

Therefore, option C is appropriate.

why is the elastic rebound theory compared to a rubber band

Answers

From an examination of the displacement of the ground surface which accompanied the 1906 earthquake, Henry Fielding Reid, Professor of Geology at Johns Hopkins University, concluded that the earthquake must have involved an "elastic rebound" of previously stored elastic stress.

If a stretched rubber band is broken or cut, elastic energy stored in the rubber band during the stretching will suddenly be released. Similarly, the crust of the earth can gradually store elastic stress that is released suddenly during an earthquake.

This gradual accumulation and release of stress and strain is now referred to as the "elastic rebound theory" of earthquakes. Most earthquakes are the result of the sudden elastic rebound of previously stored energy.

The following diagram illustrates the process. Start at the bottom. A straight fence is built across the San Andreas fault. As the Pacific plate moves northwest, it gradually distorts the fence. Just before an earthquake, the fence has an "S" shape. When the earthquake occurs the distortion is released and the two parts of the fence are again straight; but now there is an offset.

This diagram greatly exaggerates the distortion. Actually, the distortion is spread over many miles and can only be seen with precise instrumentation
