Answer: Mantle plumes, Continental rifts, island arcs, and Continental arcs
Explanation:
Mantle plume is the mechanism of convecting abnormally hot rocks within the Earth's mantle. The plume head partly melts on reaching shallow depths, the plume is often invoked as the cause of volcanic hotspots.
Continental rift refers to the belt of the continental lithosphere where the extensional deformation (rifting) is taking place. Continental rift zones have important consequences and geological features, and if the rifting is successful, leads to the formation of new ocean basins.
Island arcs are long chains of active volcanoes with intense seismic activity found along convergent tectonic plate boundaries. Most island arcs originate on oceanic crust and have resulted from the descent of the lithosphere into the mantle along the subduction zone. They are the principal way by which continental growth is achieved.
Continental arc is a type of volcanic arc occurring as an "arc-shape" topographic high region along a continental margin. The continental arc is formed where two tectonic plates meet, and where one plate has continental crust and the other plate has an oceanic crust along the line of plate convergence, and a subduction zone develops.
Answer:
✓The type of sediment on the seafloor.
✓The type of rock on the seafloor.
✓The rate of sediment deposition.
Explanation:
Sea drilling cores are one way to get samples that can be used for analysis whereby some information such as type of sediment on the seafloor and type of rock on the seafloor can be known. Surface samplers can be collected from sediment at very top layers or inside deep of the ocean floor. These samples could have animals hidden, , water and some particles that can be analysed in the muddy deep, devices such as Coring devices can be used in collection of cores. The information that can be determined directly by analyzing seafloor drill cores are;
✓The type of sediment on the seafloor.
✓The type of rock on the seafloor.
✓The rate of sediment deposition.
Women who enjoy a higher social status are likely to be more wealthy and as a result, they tend to be more educated (this is both a result and a reason for wealth). They will also often choose to have less children and will typically have a better healthcare.
So the correct answer is:
B. Women who enjoy a higher social status are usually more educated than women of a lower social status.
Answer:
Fast-moving lava can kill people and falling ash can make it hard for them to breathe. They can also die from famine, fires and earthquakes which can be related to volcanoes. People can lose their possessions as volcanoes can destroy houses, roads and fields
