WHAT IS ACID RAIN?
Is a term refering to the deposition of wet and dry acid components when it rains,snow fog…
WHO IT IS FORM?
Acid rain is componed by mallority sulfur dioxide, but it also have nitrogen oxides that reacs on water.
THIS PHOTO SHOWS HOW THE ACID RAIN IS FORMED
The consequences the acid rain has are:
1-Increases the acidity levels of rivers, lakes and seas. This can kill aquatic life.
2-Has been found to destroy the roots and leaves of many forests.
3-Can erode buildings and monuments
THIS PHOTO SHOWS AS THE FIRST PHOTO HOW THE ACID RAIN IS FORM BUT ALSO THE CONSEQUENCES IT HAVE
RELATION WITH NITROGEN CYCLE
In the nitrogen cycle some of the molecules reacts with sulfur dioxide and water to form acid rain.
I get this imformation from:
¿HOW IS ACID RAIN FORM?
¿HOW AFFECT ACID RAIN TO RIVERS AND AQUATIC MAMMALS?
Is a bear native largely within the Arctic Circle. It is the world’s largest land carnivore and also the largest bear. An adult male weighs around 350–680 kg, while an adult female is about half that size.
Each pregnant female digs a maternity den consisting of a narrow entrance tunnel leading to one to three chambers.
WHY ARE IN EXTINTION?
Human hunt polar bears to used the fur at trousers or to make footwear.
The tick gets the blood it needs to survive, but the
other animal is harmed by the tick transmitting disease into its blood.

Mendel discovered that when crossing white flower and purple flower plants, the result is not a blend. Rather than being a mix of the two, the offspring was purple flowered. He then conceived the idea of heredity units, which he called “factors”, one of which is a recessive characteristic and the other dominant.
1-The Law of Segregation states that when any individual produces gametes, the copies of a gene separate so that each gamete receives only one copy. A gamete will receive one allele or the other.
2-The Law of Independent Assortment, also known as “Inheritance Law” states that alleles of different genes assort independently of one another during gamete formation.
is the result of a sudden release of energy in the Earthś crust that creates seismic waves. It intensity is mesure on Mercall scale.
