Answer:
Option (4)
Explanation:
Seismic P and S waves are generated during an earthquake that has the potential to propagate through the interior of the earth. P waves are also known as the primary waves and they move in a compression and extension way in their direction of propagation. S waves are shear waves. This P waves travel faster than the S waves and can travel in both solid as well as in liquid. Whereas the S wave can travel only through solids. They get absorbed when they reach the core-mantle boundary. These two waves are helpful in determining the epicenter of an earthquake by recording the arrival of these waves.
Hence, the correct answer is option (4).
In Canada, the diamonds are most likely to be found in the mines. The mines contain lots of materials like diamonds, silver, gold,
Answer:
There is no such thing as "earthquake weather". ... Very large low-pressure changes associated with major storm systems (typhoons, hurricanes, etc) are known to trigger episodes of fault slip (slow earthquakes) in the Earth's crust and may also play a role in triggering some damaging earthquakes.

Explanation:
Water vapour is important for a number of different reasons, but its presence in the atmosphere is one of the most important. Water vapour is present within the atmosphere in varying amounts but is a vital component of the hydrologic cycle. In the atmosphere, water vapour can exist in trace amounts or even make up as much as 4% of the atmosphere. This concentration depends largely on where the water vapour levels are measured. On average, the value of water vapour in the atmosphere is 2-3%. In arid or very cold locations - such as polar regions - the amount of water vapour in the air is much lower.[4]
Even on a clear day, water vapour exists in the atmosphere as an invisible gas - unlike clouds which are droplets of liquid water that can be seen. If the conditions are right, water vapour in the air can collect on small particles of dust, salt, or smoke in the air to form small droplets. These droplets gradually increase in size and over time become various forms of precipitation. Since water vapour is so prominent in the atmosphere and forms precipitation, water vapour is a major component of the hydrologic cycle. When water holding areas are heated by the Sun, some of the water being held evaporates and becomes vapour, powering the cycle.[5]
In addition to being created by evaporating water, plants are capable of producing water vapour through a process of transpiration.
1- The terrestrial lithosphere is composed almost of 80% by igneous rocks, they are also known as magmatic rocks and are formed at high temperatures due to magma solidification, they come from the superior mantle and terrestrial coast. Its texture is super resistant with significant hardness to obtain minerals and other derived materials. They can be divided into extrusive and intrusive.
2- Through experiments, Bowen has defined a sequence of mineral formation when a magma begins to cool. There are two types of magmatic differentiation defined by Bowen, the continuous series and the discontinuous series. In the continuous series the internal structure of the magma is not altered and all minerals have iron and magnesium, they are formed: aluminum, silica and sodium and calcium.
In the discontinuous series decreasing the temperature reacts the previously formed mineral with the existing liquid, and thus a new mineral with different internal structure and composition is formed. They are formed: olivine, pyroxena, amphibole and biotite.
