Create AccountMotor vehicle registration figures appear for the first time in The Canada Year Book for 1916-17. It was in this year that the Year Book accorded motor vehicles a new status as the most important means of transportation in Canada.
Canadian agriculture changed rapidly between 1850 and 1900, and changes in agricultural implements both caused and reflected changes in other sectors.
In Canada the 2 basic methods of producing electric power are hydroelectric generation, based on the energy contained in flowing water, and thermal generation, based on the production of steam.

An agreement signed with the US National Aeronautics and Space Administration (NASA) led to the launching of a series of 4 Canadian satellites, beginning with Alouette 1 (on 29 Sept 1962) from the Western Test Range in Vandenburg, California.
A wildlife preserve is an area of land or water set aside from at least some forms of development or recreational use, particularly from industrial use, hunting and motorized recreation, to protect wildlife and their habitats.
ALS is as common as Multiple Sclerosis. It seems to be striking people who are younger and younger.
"Plant" refers to familiar land plants, and also to aquatic plants, mosses, liverworts and algae plants. Although not technically plants, fungi and bacteria are often included. Palaeobotany is the study of ancient plant life using fossil evidence. Plant fossils are found coast-to-coast in Canada, from 45-million-year-old mosses in British Columbia to fossil forests on Axel Heiberg and Ellesmere islands in the Canadian Arctic.
From descriptive beginnings as the geography of the sea, oceanography has matured into a quantitative and multidisciplinary science bringing together experts from many basic fields.
Humidity is related to the amount of moisture or water vapour in the air. Although invisible, water vapour is always present in the atmosphere.

For mankind, the adventure began at 9:07 a.m. Moscow time on April 12, 1961. A Soviet air force major named Yuri Gagarin blasted into the Siberian sky aboard a five-ton spacecraft and the world marvelled at the astounding news that he had landed safely after circling the Earth in just 108 minutes.Most people would no doubt balk at having to stand on the roof of an elevator as it drops slowly into a dark mine shaft sunk more than a mile into the ground. Not physicist Duncan Hepburn, 53, who shrugs off the task as just another part of his job. Some job.
Electricity is a property of the atomic structure of matter, and is manifested as attraction between 2 oppositely charged bodies or repulsion between 2 similarly charged bodies.
The importance of transportation to a trading nation as vast as Canada cannot be underestimated. The great distances between mines, farms, forests and urban centres make efficient transport systems essential to the economy so that natural and manufactured goods can move freely through domestic and international markets. Transportation has and will continue to play an important role in the social and political unity of Canada.
Climate change occurs when long-term weather patterns begin to shift. These periods of change have occurred throughout the Earth’s history over extended periods of time. However, since the Industrial Revolution the world has been warming at an unprecedented rate. Because of this, the current period of climate change is often referred to as “global warming.” Human activities that release heat-trapping greenhouse gases, such as the burning of fossil fuels, are largely responsible for this increased rate of change. The implications of this global increase in temperature are potentially disastrous and include extreme weather events, rising sea levels and loss of habitat for plants, animals and humans. In Canada, efforts to mitigate climate change include phasing-out coal-fired power plants in Ontario and instituting a carbon tax in British Columbia.

MATHEMATICS spawned the computer in the 1940s and gave it its name. Its first application was the computation of theoretical ballistic tables for traditional bombs, but calculations for the atomic bomb and then for guided missiles soon became the driving force for computer development.
Long before formal study of plants began in Canadian academic institutions, they were studied by explorers and talented amateurs.
Technological innovation is essential for economic growth and for the improvement of the quality of life. Industrial research and development (R & D) is at the heart of the innovative process.
