Answer:
Explanation: The United States of America and Canada have one of the worlds oldest environmental partnerships. The various ways they're partnering to better the environment include:
1. The U.S. - Canada Air Quality Agreement.
This Agreement was signed in 1991 with the aim of working towards the reduction of air emissions which cause cause acid rain. The Agreement was later expanded in the year 2000 with the goal of reducing transboundary smog emissions under the Ozone Annex.
2. The Great Lakes Water Quality Agreement.
This Agreement was initially signed in 1972, and amended in 2012. The goal of the Agreement is to provide a mechanism that involves the effort and cooperation of both countries, that will be geared toward the protection of the Great Lakes Basin ecosystem.
Answer:
Option: D. It cooled very slowly.
Explanation:
Iceland is known as the Land of Fire. The country is present in the plate boundary of the North American and Eurasian tectonic plates. Being on the top of the Ring of Fire, it has active volcanoes. Hexagonal basalt columns formed from a volcanic eruption. Basalt columns are the result of a cooling process that changes the appearance of the lava. Basalt is a volcanic rock rich in iron and magnesium created from the heated magma that emerges as lava during an eruption.
The photograph given below is from Icelandic national park Jokulsargljufur.
The apparent brightness is defined by how much light we get pretty much. The formula is:
This takes into account that the light is spreading out to a sphere that has the surface given by 4πd^2.
We have that d=20 ly and 1 ly is 9.46*10^12 km or 9.46*10^15m.
Hence, d=20*9.46*10^15=189.2 *10^15 m
Now, we can substitute the d value and calculate that L=<span>8.45184*
W/m^2</span>
<span>The only time I think it should be allowed to disrupt another citizens group is when that persons group is promoting and acting upon ideas that interlope anothers happyness, property, or well being. I think if someone is wrong doing something innocent then you have to wrong do them to put an end to it. So when they say "forget their rights" you gotta say "forget their rights". It should be completely an eye for an eye in an incident such as this one. Fighting fire with fire will only burn everything down but thats exactly what you want to happen when it comes to a matter such as this one.</span>
The statement which is given above is true.
<u>Explanation:</u>
Acid deposition or acid rain is any form of precipitation that falls from the atmosphere in the form of rain. Acid rain falls on the ground in dry or wet forms. Acid rain falls in the form of sulphuric acid or nitric acid.
This type of rain results in the deposition of acids on the ground or surface. Acid rain and acid deposition is harmful for the living beings. It damages the buildings, cars as well as crops. Acid rains can be prevented by not allowing the burning of fossil fuels.
