Answer:
Mt. Pinatubo is one of the contrasting volcanoes that erupted violently in the year 1991, being the second strongest volcanic eruption that took place on earth in this entire century.
The 3 hypothesis that was proposed in order to describe the seismic activity of Pinatubo includes-
- The magma rising upward to the surface from the interior of the earth, erupting through the crater of the volcano.
- The eruption led to the releasing of a large number of volcanic gases into the atmosphere.
- The earthquakes are produced due to the continuous tectonic activities that are primarily caused when the earth's crust moves over the layer of viscous asthenosphere.
A large number of volcanic gases are released such as sulfur dioxide (SO₂), methane (CH₄), Hydrogen sulfide (H₂O), Carbon monoxide (CO), and other gases, due to the formation of convection currents and rising up of magma from the mantle, creating volcanic eruptions at the surface
Answer:
A oxygen
Explanation:
For plant growth nitrogen, potassium and phosphorous are the three main elements needed. oxygen is expelled from plants. Plants doesn't need oxygen
