Answer:
b. dissolve in the nitrogen of the air.
Explanation:
We can say that volcanic ash travels long distances when mixed with nitrogen in the air. Nitrogen is one of the most prevalent elements in the air and that is why it is so easy for ash to move. Furthermore, this is why they are so harmful to humans, as they can be breathed.
Volcanic ash can be moved through the air in large quantities, when this happens, the event is called a plume of ash, as it promotes the movement of real ash columns.

explain why mantle convection occurs
Answer:
Mantle convection is the very slow creeping motion of Earth's solid silicate mantle caused by convection currents carrying heat from the interior to the planet's surface. [1] [2] The Earth's surface lithosphere rides atop the asthenosphere and the two form the components of the upper mantle .
Explanation:
The mantle is heated from below (by the core), and in hotter parts, it rises (is buoyant), whereas in colder areas, it sinks.Convection cells are created as a result, which causes mantle material to move horizontally near the Earth's surface.
Mantle convection occurs for what reason?
Because relatively hot rocks are less dense and rise in a gravitational field while relatively cold rocks are denser and sink, mantle convection happens.When hot rocks rise, heat is advected upward, and when cold rocks fall, cold is advected downward; this counter flow is the same as an upward heat flux. Several tectonic plates that make up the lithosphere are continuously being generated or eaten at plate borders.As mantle is added to a plate's expanding boundaries, which is related to the spreading of the seafloor, accretion takes place.The rising element of mantle convection is up welling beneath the spreading centers. When highly heated particles in a liquid or gas move and replace less heated particles, convection takes place.Convection is the process through which heat energy is moved from heated areas to colder ones.When heated, gases and liquids both expand .A convection cell cannot form without a heat source.The heat source warms the fluid, which is then pushed away.The fluid inevitably cools after starting to lose heat.The flow of newly heated matter drives this colder, denser matter back toward the initial heat source. Convection, a thermally driven process whereby deep heating causes material to expand and become less dense, leading it to rise while being replaced by complementary cool material that sinks, is the primary method of heat transport in the Earth's mantle. Any fluid, including boiling water, soup (where the cells may be recognized by the particles they transport, like as rice grains), the ocean, or the surface of the Sun, can produce convection cells, also known as Hadley cells. Convection causes the water at the bottom to expand and become lighter when water is heated.The cooler molecules then sink to the bottom as the heated ones rise to the top.Then, these colder molecules warm up. Convection is the process of warm fluid continuously rising above cold fluid.For instance, if you heat a bucket of water and dip your hand into it before removing half of it, the other hand will indicate that the water is chilly.Convection is the cause of this .The difference in temperature between the two fluid components allows the heat energy to be transported by convection.Hot fluids have a tendency to ascend while cold fluids have a tendency to sink due to this temperature differential.Convection current is produced as a result within the fluid. These currents receive their heat from both the mantle and the Earth's core.Mantle material rises slowly through the asthenosphere in the form of hot columns.The hot material expands out and pushes the colder stuff out of the way near the top of the asthenosphere. The commonly accepted, oversimplified theory for why tectonic plates move is that they are propelled by currents in the upper mantle, the slowly flowing layer of rock just beneath the Earth's crust.Colliding currents cause plates to collide.Currents that diverge pull them apart. Mantle convection is the term used to explain how the mantle moves when heat is transferred from the blazing core to the brittle lithosphere.The mantle's temperature gradually drops over extended periods of time as a result of below- and above-surface heating and cooling.To learn more about mantle convection refer

why volcanoes are dangerous?
Answer:
the lava emitted is harmful
high energy release can cause landslides
it can burn crops
it releases harmful gases. plz mark brainliest
Answer:
Volcanoes spew hot, dangerous gases, ash, lava, and rock that are powerfully destructive. People have died from volcanic blasts. Volcanic eruptions can cause damage hundreds of miles away. Volcanic ash causes airplane engines to fail, destroys crops, contaminates water, and damages electronics and machinery. The ash carpets the ground, burying everything, sometimes even causing buildings to collapse.

What is similar about the desert and savanna zones in Africa?
Both contain stone plateaus.
Both experience limited rainfall.
Both contain abundant grasslands.
Both experience high temperatures.
please choose from above
Answer:
Both experience limited rainfall.
Explanation:
no water
The similarity between desert and savanna zones in Africa is both have high temperatures. Thus, the correct answer is option D.
What are savanna zones?A savanna, also known as a savannah, is a mixed woodland-grassland ecosystem distinguished by trees that are sufficiently spaced so that the canopy does not close. The open canopy allows enough light to reach the ground to support an unbroken herbaceous layer dominated by grasses.
Despite their dense tree cover, savannas have an open canopy. Savannas are commonly thought to have widely spaced, scattered trees. However, tree densities are higher and trees are more regularly spaced in many savannas than in forests. Savannas are also characterized by seasonal water availability, with the majority of rainfall confined to one season.
Therefore, both experience high temperatures.
