Answers

Answer 1
Changes in the orbit of the earth caused the ice sheets to spread across Canada. 
Answer 2

Changes in the earth's orbit allowed the ice sheets to extend over Canada, resulting in nearly all of Canada and portions of the northern United States being buried by thick glacial ice around 15,000 years ago.

What was the thick glacial ice like about 15,000 years ago?

The Laurentide Ice Sheet was a vast sheet of ice that covered millions of square miles, including much of Canada and a major chunk of Northern America, several times throughout the Quaternary glacial epochs, from 2.58 million years ago to the present.

Giant ice sheets have grabbed the world at least 15 times in the last 2.5 million years. Glaciers carved out around one-third of the earth's landmass. They spanned from present-day New York to Montana, and from Ohio to Hudson Bay, Canada, and were up to 2 miles thick at times.

Due to changes in the earth's orbit, the ice sheets were able to spread across Canada, burying virtually all of Canada and parts of the northern United States under thick glacial ice roughly 15,000 years ago.

Therefore, option B is correct.

Loss of which habitat has had the greatest impact on the earth's biodiversity

Answers

tropical rainforest 
because loss on this habitat will have a greater impact

Answer:

Tropical rainforest

Explanation:

The tropical rainforest forms the major biodiversity on earth. It is because this habitat is located in the tropical region, where there is a high amount of sunlight and rainfall every year. The most essential nutrients are received by the organisms (both plants and animals) living in this habitat. Due to this reason, it supports a large number of living species in this region.  

The plants and trees also play an important role by providing the highest amount of oxygen from this region which is distributed globally.

So, this tropical rainforest is the most important habitat. The loss of this habitat will directly have a great impact on the earth's total biodiversity.

Compare and contrast the education systems in India, China, and Japan.

Answers

The Chinese education system consists of six years of primary school, three of lower secondary and three of upper secondary. The state mandates every child to attend nine years of school - six years of primary and three of lower secondary. At age 15, they are "empowered" to choose their upper secondary program in either academic or vocational fields.

China raised the bar for entry to the teaching profession in the 1990s. All primary school teachers needed a diploma and all teachers in secondary schools had to be degree-holders with professional certification. China was the first forward-thinking district to mandate continuous professional training for its teachers. Every teacher is expected to complete 240 hours of professional development in five years.

As evidenced in China, through a well-thought out, focused and step-by-step system of school education reform, it is indeed possible to aim at a bank of holistic schools in our cities. But for that our schools and the systems which govern them may have to go through a crucible of experimentation and be brave about embracing innovation and partnership.

Indian culture is ruled by three things : peace, love and religion.Education is the same, families are very close, and parents are being extremely tolerant with their kids. They will still give the guidelines to a good education, they know what is good and what is bad and they teach it to their kids, but I have always seen parents finally backing down to the will of their kids. If the kid wants a new toy, they’ll buy it ; if the kid does not want to finish it’s food, well, that’s ok. If he likes to do this, does not like to do this, his desires will always be fulfilled.
