Question

3. As the magma chamber became depleted, the volcano that erupted in the previous number became extinct. The surface processes of the earth (weathering and erosion) soon took over. Due to the uneven erosional and weathering rates, the northern_side of the volcano is made up mostly of basaltic lava flows and the southern side is made up mostly of graniticlava flows. (20 pts) a. Describe the different styles in the resulting b. If your business is in agriculture, which side of the c. If there is an ocean on the southernside of the topography? (flat vs steep topography) volcano are you going to invest? Why? volcano, would it be a wise investment to build a resort? How will the sand look like? d. The gradient of the stream that drains from the eroding volcano starts from a steep angle and becomes less shallow as it approaches the ocean. How would you describe the energy of the water as it flows down oramnsetce and the degree

Explanation / Answer

Low viscosity low viscosity basaltic magma flows easily down slope away form the summit vent. Low low viscosity of the magma allows the lava to travel down slope on a gentle slope, but as it cools and its viscosity increases, its thickness builds up on the lower slopes giving a somewhat steeper lower slope.due to accumulations of material eroded from the volcano and to the accumulation of pyroclastic material, gentle slopes occur near base.The basalts spread huge areas of relatively low slope and build up plateau.

B. Southern side is grantic. I will choose that beacuse, usually granatic magma takew long tuke to cool down and crystalise to solid rock. This allows minerals to form in plenty. Contains 75% of oxygen and silica, and remaining percent it has no. Of elements like potassium and aluminium.

C. Yes we can build a resort. Mostly granute magma will result in coarse structured rock, more silica and oxygen. Basaltic magma is fine grained. Mostly ocean floors are basalt. But continents wil be granite.
