The Great Barrier Reef is special because it is by far the largest reef in the world. It is consisted of around 2,900 individual reefs. The size of this reef is approximately as the size of Germany. There are over 900 islands that are stretched over 2,600 km along the the reef. The Great Barrier Reef is so marking and big, that even though it is below water it can actually be seen from space. The ecological importance of this reef is enormous as it is a home for thousands of species, with approximately 10% of all fish species in the world living in it. Because of its beauty and numerous attractions, the Great Barrier Reef is one of the most visited tourist destinations, and the Australian economy manages to generate between 5 and 6 billion Australian Dollars annually from it. Unfortunately, all of the human activity has been affecting this reef very negatively, and little by little part of it is dying out.
Light is not different. First sentence says "light can move through matter or through empty space."
An insect that has been fossilized in near-perfect form most likely has been entrapped in amber
Answer:
- Liquid (molten metals/rocks)
- Silica
- Gasses
Explanation:
The magma is a product of the mantle layer. The temperatures in this layer are very high, and the pressure is also much higher than on the surface. This leads to creating a melt out of the rocks/metals in it, thus creating a thick liquid out of them. Apart from the liquid of molten rocks/metals, a major component of any magma is the silica, which actually determines its behavior ones it reaches the surface of the Earth. The third important component of the magma are the gasses. The gasses are forming bubbles in the magma, and depending on the amount of silica, they can remain trapped and than cause explosions on the surface, or they can escape the magma easily if the magma is not highly viscous.
