What is a spring tide? When and why does it occur?

Answers

Answer:

Spring tides happen just after every full and new moon, when the sun, moon and earth are in line. That's when lunar and solar tides line up and reinforce each other, making a bigger total tide.

A spring tide occurs when there's a new or full moon. Because it follows the moon's lunar cycle, a spring tide happens twice per month. With the moon and sun roughly aligned the tides of Earth are on average slightly larger than usual.

Alan lives in an area that has a huge park. Moreover, there is good quality of air and water in his region. What is the possible consequence of such conditions?
A.
premature deaths
B.
asthma
C.
cardiovascular diseases
D.
high life expectancy

Answers

Answer:

D. High Life Expectancy

Explanation:

Air pollution lowers life expectancy and causes tons of premature deaths in areas. The area that Alan lives in has good air quality which means that there is obviously going to be a increase in life expectancy. If water quality is bad in an area it can cause chronic illnesses (such as cancer), gastrointestinal illnesses, and even effect the nervous and reproductive systems in a bad way. So the fact there is good water quality in the region the area Alan lives in, he is pretty much guaranteed for higher life expectancy. Therefore the best answer is Option D.

With the findings of the 2016 Census count on population and dwellings, Statistics Canada gives Canadians a first look at the most recent national statistical snapshot.

The census counts 35,151,728 persons who said they lived in Canada on May 10, 2016, and displays population growth patterns across the country.

The organization will provide the complete spectrum of census data during the following year, as Canadians commemorate 150 years since Confederation, in order to portray a truthful picture of Canadians' lives and communities.

In 1871, the first census following Confederation recorded 3.5 million people in Canada, while the population figure in 2016 was ten times higher. When Canadians celebrated the 100th anniversary of Confederation in 1967, that number had risen to 20.0 million people (1966 Census).

Canadians have been making their way west for many years. The four founding provinces of Ontario, Quebec, New Brunswick, and Nova Scotia housed the majority of Canadians in 1871, whereas Western Canada was lightly populated. Manitoba, Saskatchewan, Alberta, and British Columbia accounted for over a third of the population in 2016.:
