Winter. It can kill plants, livestock; and re-shape the surrounding area.
Answer:
D. Heavy rainfall saturated the soil and destabilized the over-steepened slope.
Explanation:
The mud slide must have occurred in La Conchita California due to heavy rainfall which saturated the soil and destabilized the over-steepened slope.
Mud slide or mud flow is a form of mass wasting in which slope moves downward due to instability of the materials. They usually influenced by the effect of gravity on steep slopes.
- Prior to the mass moving event on the in the county, there was an unprecedented 14-15days streak of rainfall.
- The rain saturated and lubricated the soil bringing a reduction in their cohesion and ultimate movement.
- This led to the sliding down of the masses on the slope.
Answer:
Wastewater from fracking operations is injected into porous rock formations, which can induce seismic activity.
Explanation:
- The environmental concerns of the fracking can be linked to the increase of the potential for the oil spills that harm the coil and the surrounding vegetation and can cause the earthquakes due to the high pressure that is used to extract the oil and the gas from the rocks and storage of the excessive wastewater on site.

Answer:
c. The downgoing slab takes along water, and that water lowers the temperature at which rock melts to allow melting in and near the slab.
Explanation:
A subduction zone occurs when one of the plates at convergent boundaries, an area where tectonic plates meet, is an oceanic lithosphere.
These oceanic plates are high in temperature on formation but as they cool, they descend into the mantle below. This descent applies pressure until water is liberated from the lowering crust. The water in turn rises into the surrounding mantle and lowers the temperature at which the rocks melt to produce magma which are partly melted rocks.
This liberation of water from the subducting crust and accompanying melting is responsible for the formation of almost all magma at subduction zones.
