O nosso planeta é extremamente vasto e ainda está longe de ser completamente explorado. Curiosamente, a maior parte da superfíci

e terrestre é coberta de oceanos e eles permanecem um grande mistério para a humanidade. Pouco se conhece sobre as profundezas do oceano, mas durante a Segunda Guerra, devido ao uso de sonares para detectar submarinos, o homem conseguiu uma série de descobertas a respeito desse ambiente. A respeito dos oceanos, podemos dizer que:
a)os oceanos, apesar de serem extremamente vastos e robustos, possuem a maior parte da fauna em sua superfície, tendo as profundezas praticamente vazias de vida.

b)as profundezas do oceano são conhecidas por serem ambientes prósperos para a vida, com abundância de luz, alimento e poucos predadores, por isso muitos peixes e outras formas de vida habitam lá.

c)os oceanos são muito profundos, possuem um solo arenoso similar a de um deserto plano em seu fundo.

d)existem indícios de que áreas que hoje são oceanos antigamente eram superfície terrestre. Essas alterações podem ser atribuídas ao movimento tectônico das placas.

Which factor does not help determine whether a volcanic eruption will be explosive or relatively quiet?
Zinaida [17]
The factor that does not help determine whether a volcanic eruption will be explosive or relatively quiet is the composition of the lava.
On the other hand, the composition of the magma, the temperature of the magma, and the amount of dissolved gases in the magma are quite important for determining this.
