This treaty was aimed at protecting the continent’s ecozone (from military operations and mineral exploitation, etc) that is essential or the planet. Due to the harsh environment on the continent, it is also inhabitable and is more or less unoccupied.
Earthquakes generate compressional waves (p-waves) and shear waves (s-waves). Compared to the speed of shear waves in a given earth material, the speed of compressional waves is the fastest.
Because of this the compressional waves are the first waves to arrive on a complete record of ground shaking. They are also called P waves, which derives from this fact - P is an abbreviation for primary, first wave to arrive.<span>They typically travel at speeds between ~1 and ~14 km/sec.</span>
Mediterranean Sea is full of resources. The temperate climate provide diverse and abundant agriculture, trade and knowledge exchange and technology throughout the region. Since the waters are relatively smooth, it makes trade easier an cultural exchange.
Answer:
igneous rock
Explanation:
There are three main kinds of rocks, sedimentary, metamorphic and igneous.
The igneous rocks are the ones that formed from a hot source like magma inside the soil, as it gets to the surface of the Earth it goes cooling. If it cools almost in the surface of the Earth then is consider a plutonic rock.
Plutonic Rocks have a big quantity of minerals, since they cool under a big pressure, these minerals get together forming a solid rock.
By passing the time the granites of minerals can be easily seen at naked eye, like the characteristics of these sample.
