Answer: Option (D)
Explanation: When two oceanic plate moves in opposite direction due to the convection current generated in the mantle, the crust gets thinner and eventually magma comes out to the ocean floor, forming new crust. Due to this divergent movement, a chain of volcanic arc are formed in their vicinity.
For example, the Hawaiian.
Hence the correct answer is option (D).
D, 8100 seconds is equal to 2 hours and 15 minutes
Answer:
a) decreases and larger sediments are deposited first
Explanation:
As the Niagara River enters the Lake Ontario, it is coming up to a large body of water that is stopping its flow as it enters in it. This results in a loss of velocity. Because the river losses its velocity, it is no longer able to carry the sediments with it, thus it starts to deposit them. The largest sediments are deposited first as they weigh the most, so the river needs greater velocity to transport them. As the velocity is becoming smaller and smaller, the medium sized sediments come next for deposition, and in the end are the smallest sediments that are deposited when the river totally losses its velocity.
On locations where tectonic plates diverge or converge, volcanoes can be found. A volcano consists of a deep magma chamber where magma accumulates, pipes that lead to surface vents, and the vents through which lava is emitted during a volcanic eruption. Volcanoes are often known to have a mountain-like shape<span>
