Briefly explain how physical weathering enhances the rate (speed) of chemical weathering?
nirvana33 [79]

Answer:

Physical weathering enhances the rate of chemical weathering .

Explanation:

Physical weathering is the breaking down of rocks by various processes like freezing and thawing without altering the rocks chemical composition.

While, chemical weathering involves the disintegration and dissolution of rocks by the chemical processes like oxidation , carbonation and solution processes etc.

Generally a fractured rock can easily be weathered by chemical agents rather than a normal fractured rock.

So ,

when a rock is already subjected to physical weathering, the rock will develop cracks on it and when the chemical agents comes in contact with that rock, the chemical solution will penetrate into those cracks and will dissolve the rocks at a rapid rate.

What three religions are in constant conflict over the land in the Middle East? Describe the claim of each.​
Ymorist [56]

Answer:

Judaism, Christianity, and Islam are in constant conflict over the land in the Middle East.

Explanation:

The Middle East is a region that is important for many reasons, and one of them is religious importance. This area is actually the birthplace of three major religions, the so-called Abrahamic religions. The three religions that emrged in this region are Judaism, Christianity, and Islam, in that order.

Judaism came first, and what is now Israel is considered as the holy land for this religion. Despite many attempts to forcefully removing the Jews from this area, some of them still managed to survive there and many more came back in the last century to reclaim what they consider as historically theirs.

Christianity emerged from Judaism. What is now Israel is also holy to it, and especially the city of Jerusalem. The claim of the Christians for this region is that their religion emerged there and its holy places have to be in their hands and no one else.

Islam came last, emerging from Christianity. Soon it became the dominant religion in the region through conquest and assimilation. It has been dominant in the area for over a milennium, so the claim is that it is historically theirs and since they managed to conquer the place it belongs to them.

Some of our best deep space-telescope images show some galaxies that are 100 times fainter than the faintest objects that can be
Ksenya-84 [330]

Answer:

True

Explanation:

Deep space telescopes are fitted with the faint object cameras, that are way better than ground-based spectroscopically functioning telescopes. The Subaru telescope at Hawaii observed the faintest object ever from a ground-based telescope. But when compared to other deep-space telescopes like Hubble's deep space telescopes it's very small. They have reached up to a magnitude of 31 , which observes 20 times fainter objects .
