Answer:
<u>e. All convergent plate boundaries are subduction zones</u>
Explanation:
- It's well known that any place either on land or ocean when is subdued into the earth's mantle is formed by a subduction zone where the plate boundaries collide either oceanic or continental boundaries this collision can result from the earthquake and volcanic eruptions.
- These collisions thus lead to the creation of mountains and volcanoes at greater altitudes as the place gets elevated and as a result of the slab push and pull as many earthquakes generally occur in this shallow zone also named as the Benioff zone.
- Plates dip here at an angle of 45 degrees and thus form these internal subduction zones that lead to lithospheric density differentiation
Answer:
C. include global warming, which is greatly enhanced by society's production of greenhouse gas
Explanation:
Human activities such as burning of fossil fuel, industrial waste has lead to the emission of greenhouses such as carbondioxide, carbon monoxide, methane, chlorofloro carbon accumulation of which in the atmosphere leads to global warming as a result of the depletion of the ozone layer and the direct impact of sun on the earth.
The depleted ozone layer has lead to the constant and high temperature
that is affecting the earth.
Green plant,trees are natural users of carbondioxide but deforestation of this trees has also reduce the use of carbondioxide making it abundant in the atmosphere.
Answer:
d. may belong to any of the three primary rock types
Explanation:
- Metamorphic rock is the transformation of any of the existing rocks through the process of metamorphism i.e associated with changes in form. When the original rocks are subject to intense heat from below. The Pressure over these rocks causes profound hearing and compaction of rocks particles and matter.
- About 12% of the earth's surface is made up of metamorphic rocks that are either derived from the igneous or sedimentary rocks based on texture, chemical, and mineral assemblage.
- Some common examples of these rocks are gneiss, slate, marble, and schist, etc that have been formed from the sedimentary processes.
Terrestrial: Mercury, Venus, Earth, Mars
Gas: Jupiter, Saturn, Neptune, Uranus
