From its original territory in Eastern Europe, Russia managed to expand greatly and become the biggest country in the world by far, and one of the biggest reasons for that was the relatively easy terrain, and the lack of natural barriers that were going to set the Russians back.
- harsh climate;
The fact that the climate is very harsh in the territories that Russia gained, meant that very small amount of people live in those areas, thus the resistance was relatively small and insignificant, so the Russians managed to gain the desired territories with relative ease.
Sedimentary rocks that are formed due to the accumulation of sediments that are derived from the deposition of small particles and their cementation of minerals and organic particles in the seafloor by the impact of various geological and earth processes like the wind, water, and glacier erosion.
Earth's crust is covered by 73% of sedimentary rocks and about 8% of the total crustal surface. Based on their formation, these rocks are thus classified as Siliciclastic, Carbonate, Evaporite, Iron-rich, and Phosphatic sedimentary rocks.
The color of these rocks is always determined by the iron and oxide contents, their size texture is a result of the density and permeability of the rocks like in the case of sandstone and limestone.
The relationship between the plate tectonics and the earthquakes is explained through the seismic waves that travel; through the three-layer of the earth from core to mantle to crust.
Earthquakes are directly related to plate boundaries as these are areas where these waves come out in the form of shocks and shaking of lands thus we expect of seeing three types of boundaries as Convergent, Divergent and Transform.
Answer: Plants perform photosynthesis more efficiently when carbon dioxide is abundant. This in turn reduces the amount of carbon dioxide in the atmosphere and increases the amount of oxygen
Answer: Shield volcanoes are formed by lava flows of low viscosity - lava that flows easily. Consequently, a volcanic mountain having a broad profile is built up over time by flow after flow of relatively fluid basaltic lava issuing from vents or fissures on the surface of the volcano.
