Answer:
Laccolith
Explanation:
A laccolith is an intrusion with the shape of a mushroom that grows under the earth's surface. This happens when liquid magma exceeds its way between 2 layers of rock, causing the overlying sediments to puff out as the feature increases. Eventually, this causes the origin of small hills and mountains surrounding the top of the mountain.
The answer is Mediterranean Sea
Answer:
Iron cannot release energy either by fission or fusion.
Explanation:
When a high-mass star runs out of hydrogen inside its core, it starts burning helium, and then heavier elements until it reaches iron.
Nuclear fusion of iron cannot occur, because the amount of energy required for the fusion of two nuclei of iron is larger than the energy released.
Therefore, when all the lighter elements lighter than iron have already fuse together, the star cannot burn any other element, so the nuclear fusion inside the core stops and the star collapses on itself, producing a huge explosion known as supernova.
Answer:
Caves, caverns, sinkholes, funnel-shaped holes, underground rivers and lakes
Explanation:
The karst topography is found at places that are dominated by rocks made out of calcium carbonate, better known as limestone. These rocks react with the water very easily and get dissolved from it very easily. Because of the large scale dissolving, this type of topography has numerous specific features. Some of the most common features in the karst topography are the caves, sinkholes, caverns, funnel-shaped holes, underground rivers, underground lakes etc. All of them are very attractive and understandably cause a lot of interest, thus they are often tourist destinations, but more importantly of big scientific interest. The biggest problem with this topography is that it is generally not stable, and it is very common that the rocks can crumble, which makes them relatively dangerous if visited at certain periods of the year, especially when there is more precipitation.
