Answer: A) Under emissions trading programs, pollution levels will not fall sufficiently for optimal abatement.
Explanation:
First conceived in the seventies to fight acid rain and now useful in the battle against climate change, emissions trading is a program targeted at reducing emission by companies.
Under this scheme, every company that produces emissions will need to hold a permit for a limited amount. If they produce more than their stated limit, they would need to buy from other permit holders who produce lower emissions.
While this program can set a limit of total emissions, it will not succeed in reducing pollution levels below this limit.
Airborne fragments<span> of lava, called tephra, are ejected from a single vent. The lava cools rapidly and builds up around the vent, forming a crater at the summit. Cinder cone volcanoes are fairly small, generally only about 300 feet (91 meters) tall and not rising more than 1,200 feet (366 meters).</span>
Igneous rocks are formed as magma solidifies on the earth surface.
The process that might have formed this rock is:
A. melting underground, violent volcanic eruption, and solidification above ground
<h3>Igneous Rocks</h3>
Igneous rocks are known to be rocks that are formed when the magma melts underground and rises up to the earth surface via volcanic eruptions.
When they rise to the earth surface, they cool and solidify. This process will then result to the production of crystals.
Intrusive and extrusive rocks are formed in this process.
