Explanation:
Tectonic Earthquakes
Earthquakes caused by plate tectonics are called tectonic quakes. They account for most earthquakes worldwide and usually occur at the boundaries of tectonic plates.
Plate tectonics
Induced Earthquakes
Induced quakes are caused by human activity, like tunnel construction, filling reservoirs and implementing geothermal or fracking projects.
Volcanic Earthquakes
Volcanic quakes are associated with active volcanism. They are generally not as powerful as tectonic quakes and often occur relatively near the surface. Consequently, they are usually only felt in the vicinity of the hypocentre.
Collapse Earthquakes
Collapse quakes can be triggered by such phenomena as cave-ins, mostly in karst areas or close to mining facilities, as a result of subsidence.
Answer:
Correct option are Basalt, gabbro and peridotite.
Explanation:
Igneous rocks like basalt, gabbro, dunite, diabase, and peridotite contains the olivine mineral. These are the dark coloured rocks and found within the surface of earth mostly in the areas around the tectonic plates. Olivine is known for its crystallization at high temperatures. It crystallize itself from the heat of the earth. Common olivine minerals are Forsterite, Fayalite, Monticellite and Tephroite.
Western Europe is more developed than Eastern Europe because <u>the market economy of Western Europe provides an economic advantage</u>
Explanation:
Stark differences persist between the western and eastern part of Europe. While western Europe was under the influence of Capitalism mode of production (led by the US and Great Britain), the eastern part was led by the erstwhile USSR following socialist mode of production.
Under the market economy, open competition and adaptive hand-holding by the US, western European countries prospered by leaps and bound. Marshall plan prepared by the US helped in post-war reconstruction of western Europe. On the other hand, eastern countries fell prey to the despotic rule of dictators, political instability and socialisation of assets. There were no such private assets and the important assets were nationalised. In the long run, the socialistic model of the market could not stand up to capitalism and fell in 1991 when the USSR disintegrated.
Answer:
polar region
High latitudes are dominated by floating sea ice covering much of the Arctic ocean in the north, and by the Antarctic ice sheet on the continent of Antarctica in the South.
Answer:
1. Galileo.
2. Newton.
3. Kepler.
4. Brahe.
5. Refracting telescope.
6. Reflecting telescope.
7. Astrolabe
8. Camera.
9. Radio telescope.
Explanation:
1. Galileo: he discovered details of a lunar surface.
2. Newton: he invented first reflecting telescope.
3. Kepler: he found planets had elliptical orbits.
4. Brahe: he performed a systematic mapping of sky.
5. Refracting telescope: uses a large glass lens.
6. Reflecting telescope: uses a mirror to focus light.
7. Astrolabe: tool used to determine location of a star.
8. Camera: instrument that accumulates light from an object to show more detail.
9. Radio telescope: records sounds of stars.
