<span>The most volcanically active belt on Earth
is known as the Ring of Fire, a region of subduction zone
volcanism surrounding the Pacific Ocean. Subduction zone volcanism
occurs where two plates are converging on one another. One plate
containing oceanic lithosphere descends beneath the adjacent plate,
thus consuming the oceanic lithosphere into the earth's mantle.
This on-going process is called subduction. As the
descending plate bends downward at the surface, it creates a large
linear depression called an oceanic trench. These
trenches are the deepest topographic features on the earth's surface.
</span>
<span>The crustal portion of the subducting
slab contains a significant amount of surface water, as well as
water contained in hydrated minerals within the seafloor basalt.
As the subducting slab descends to greater and greater depths,
it progressively encounters greater temperatures and greater pressures
which cause the slab to release water into the mantle wedge overlying
the descending plate. Water has the effect of lowering the melting
temperature of the mantle, thus causing it to melt. The magma
produced by this mechanism varies from basalt to andesite in composition.
It rises upward to produce a linear belt of volcanoes parallel
to the oceanic trench, as exemplified in the above image of the
Aleutian Island chain. The chain of volcanoes is called an island
arc. If the oceanic lithosphere subducts beneath an adjacent
plate of continental lithosphere, then a similar belt of volcanoes
will be generated on continental crust. </span>
Answer:
1) if mother nature pressures a species to evolve they will not evolve right therefore they past on to their offspring and the they die.
2)mass extinction occurs when something BIG happens take dinosaures for ex they were wiped out by something HUGE this was all proving by sci because of the fossils
3) the meteor (i think)
4) i don't know
Explanation:
sorry if I am wrong for any of these
have a nice day
Answer:
the process of improvement
Answer:
What role does the physical geography play in Europe's culture?
Physical features, weather-related phenomena, and local resources had a deep impact on how historic European cultures prospered, interacted, and believed their world worked. The geography and climate of the Mediterranean region, for example, directly influenced Greek mythology.
How does communism affect Europe?
The injustices of communism were not limited to mass murder alone. Even those fortunate enough to survive still were subjected to severe repression, including violations of freedom, of speech, freedom of religion, loss of property rights, and the criminalization of ordinary economic activity.
What is Europe's largest industry?
Services. The services sector is by far the most important sector in the European Union, making up 74.7% of GDP, compared to the manufacturing industry with 23.8% of GDP and agriculture with only 1.5% of GDP. Financial services are well developed within the Single Market of the Union.
Eastern Europe.
Explanation: Eastern Europe.
Cloud droplets collide to form larger droplets in a process called <u>coalescence</u>
Answer: Option A
<u>Explanation:</u>
When the drop lets of the cloud which are present in the air bang into each other, the result is the formation of a bigger drop let of the cloud and this whole process is known as coalescence.
And such big drop lets are big enough in their size which can result in the rainfall in that region. The droplet should at least reach a size of 4 mm to result into rainfall and this collision is a fast process.
