Answer:
The correct answer is A. Barrier islands are constantly moving in the direction of the longshore drift.
Explanation:
Barrier islands are islands in the form of relatively narrow strips of sand located close to and parallel to the coast of the mainland. As a rule, they are located in the form of a chain consisting of several islands, sometimes more than a dozen. The length and width of the barrier islands are related to coastal parameters, including tides, wave energy, sea level and soil composition. Some barrier islands reach a length of more than one hundred kilometers, the longest and widest is Padre Island, Texas. The shape, area and the very existence of barrier islands are variable, as they can appear and disappear in a short time on a geological scale.
These islands are formed from the longshore drift, which is forming these islands by sediment and sand accumulation. Therefore, as they are formed by this process, it is the same process that constantly moves them.
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.
I think Nigeria is the answer.
