The correct answer is A. 110GPa
Explanation:
Pressure refers to a force applied to a surface or object either by another object or factors such as the atmosphere. This is calculated considering the force applied and the area. Additionally, this factor can be measured using the unit gigapascals (GPa), which is more common in geography and related areas.
In this context, the lower mantle, which is the layer below the upper mantle has a pressure between 24GPa and 130GPa; and this is a high pressure if compared to the pressure in the surface. Thus, the estimated pressure in this zone is 110GPa because this is the only number that is between the range of pressure in this zone, while others show a higher pressure that is not found in this layer.
Eruption with low silica tends to be nonexplosive. The type of lava is Basaltic, flows easily because of low viscosity (low gas content- originates in the mantle). This type of lava comes from shield volcanoes (low angle slopes and gentle)- eg. Manua Loa Volcano and Hawaii.
I believe that the answer is Urea.
Answer:
The crust size remains constant because the older crust is melted at subduction zones.
Explanation:
The crust is constnatly created on Earth, but the crust is constantly getting destroyed as well. This situation leads to the total size of the crust being roughly at the same level, or rather constant, as one side a new one emerges, while at the same time, on the other side it gets destroyed.
The vast majority of the new crust is formed where there are divergent plate boundaries. Here, a gap opens up between the plates that move away and magma is constantly rising to the surface and creates new crust. When it comes to the destruction of crust, it occurs at subduction zones. Here, one plate moves below another plate, and as it does it reaches the upper mantle where it gets melted and recycled because of the high temperatures and pressure.
