Answer:

Parent rock - Limestone

Metamorphic rock - Marble

They contain calcite and minerals such as Mica, quartz and intergrowth of mineral crystal. They also react with hydrochloric acid. They do not have foliation.

Explain the differences between the Ptolemaic view of the universe and the new vision of the universe proposed by Nicolaus Coper
saveliy_v [14]

Answer:

The Ptolemaic view of the universe was geocentric: the Earth was at the center of the Universe, the Moon, Mercury and Venus circled around the Earth in that order, the Sun and the rest of the planets were after, and the starts were located far beyond.

The model of the Universe according to Nicolaus Copernicus was heliocentric: the Sun is at the center of the Universe, the Earth and the other planets circle around it, and the stars are far away and fixed.

What Galileo means by the statement is that neither model was incorrect, or sinful. The universe was created by divine intervention, and humans try to understand its shape. The Ptolemaic approach was an initial understanding of the divine creation, and the Copernican view was more advanced.

andriy [413]
This is actually a Maths question - although is it related to geography.

In order to calculate this, we simply need to find out how many is 80% of 1500, like this:

\frac{80}{100} *1500=8*15=4*30=120



So the answer is: 120 volcanoes are located in this area!
