Contagious diffusion is wide-spread and involves interpersonal contact.
Answer:
True
Explanation:
The mass movements are representing movements of large masses of soil, also including rocks, water, biomass in them. These movements though need certain natural conditions so that they can happen. For a mass movement to occur, there has to be a slope, and under the influence of the gravitation, once the conditions are right, there will be movement downward until it reaches a flatter spot. If the terrain is flat, then a mass movement can not occur, as the gravitation is pulling the material down, so it will not be able to move. Also, if the gravitation is lacking, the material will not move anywhere, as without gravitation, there will be no atmosphere, and without atmosphere, there will be no agents to cause the mass movement.
Answer:
The intermediate to felsic eruptions may be usually moderately to highly explosive
Explanation:
- Felsic lavas are hot, high in silica and volatiles, and have a high viscosity of fluid matter. They are thick and heavy and resistance movements.
- They thus represent the shielded nature of volcanoes etc. Fluid lava flow, tephra, lapilli, and volcanic bombs.
- Felsic magma is rich in feldspar, and silica as opposed to mafic magma which is rich in magnesium and iron.
- Felsic magma is usually acidic.
- As a result of the high intensity of volcanic eruptions, the lava is sticky and dark in color also it's bulky, etc. An example of Mount Saint Helens that erupted destroying both property and human life.
I think its third one cause it doesnt give us a,b,c,or d
