Rocky Mountain Trench

The Rocky Mountain Trench is a long and deep valley extending approximately 1,500 km from the Bitterroot Valley in northwest Montana through British Columbia to the Liard Plain just south of the Yukon Territory. Its predominantly flat floor is 3–20 km wide and ranges in elevation between 600 m and 1,000 m above sea level. With walls made of sedimentary, volcanic and igneous rock, the Trench is sometimes referred to as the “Valley of a Thousand Peaks” because of the towering mountain ranges on either side: the Rocky Mountains to the east and the Columbia, Omineca and Cassiar mountains to the west. Humans have relied on the rich resources provided by this distinctive landscape from pre-colonial times to the present.

Sunken Ships/Shipwrecks

SABLE ISLAND, a crescent-shaped sandbar 300 km east-southeast (160 nautical miles) of Halifax, is also infamous for its shipwrecks, and is known as "the Graveyard of the Atlantic," as its shifting sands have been the site of over 350 such incidents.

Hydroelectricity in Canada

Hydroelectricity is energy produced from flowing water. The amount of energy produced depends on volume and speed: the more water moving at a fast rate, the more energy produced. For this reason, many hydroelectric stations are built near waterfalls. To produce energy, water is directed toward turbines — sometimes with the help of a dam — causing them to spin. In turn, the turbines make electrical generators spin and electricity is produced. It is a renewable, comparatively nonpolluting energy source and Canada’s largest source of electric-power generation.

Natural Regions

Natural regions are intended to describe areas of the Earth's surface which possess similar qualities or attributes. They may refer to either land or water, and can vary in size. The term “natural region” is often used interchangeably with the word “ecozone.”

Article

Fungus

All members of the kingdom Fungi are commonly known by the same name, fungus. Fungi have some characteristics in common with both PLANTS and ANIMALS, yet most biologists consider them to be an independent group.

North-West Territories (1870–1905)

The North-West Territories was the first Canadian territory. It was Established on 15 July 1870. As a territory, the region became part of Canada. But it lacked the population, economic and infrastructure resources to attain provincial status. It thus fell under the jurisdiction of the federal government. It covered a vast area, stretching west from a disputed boundary with Labrador, across the northern portions of present-day Quebec and Ontario, through the Prairies to British Columbia, and north from the 49th parallel to the Arctic Ocean. The territory was subject to numerous boundary changes before 1905. At that time, the provinces of Saskatchewan and Alberta were carved out of the southwest portion of the region. In 1906, the remaining territory was renamed the Northwest Territories.

Energy in Society

Energy plays a unique and critical role in the world; no activity of any kind (no "work") can take place without the movement or conversion of energy.

River

A river is a course of water, usually growing in volume between its source and its terminus in an ocean, a lake or another river.

Environmental Movement in Canada

The environmental movement seeks to protect the natural world and promote sustainable living. It had its beginnings in the conservation efforts of the early 1900s. During this time, conservationists aimed to slow the rapid depletion of Canadian resources in favour of more regulated management. Many scholars divide the evolution of the environmental movement into “waves.” These waves are periods in time easily characterized by certain themes. While the number of waves and their characterization may differ from scholar to scholar, they’re often defined as follows: The first wave focused on conservation; the second, pollution; the third, the professionalization of environmental groups; and the fourth, climate change.

Plant

The shoot system (stem and leaves) grows upward into the light and is the site of photosynthesis; the root system penetrates the soil, anchors the plant and absorbs necessary water and minerals.

Maple Trees in Canada

Maples are trees and shrubs in the genus Acer, previously classified within the maple family Aceraceae, but now placed by some taxonomists in Sapindaceae (Soapberry family), which also includes horse chestnut (Aesculus hippocastaneum). There are approximately 150 species of maple around the world, most in the temperate zone of the Northern Hemisphere, and the majority native to eastern Asia. Ten maple species are native to Canada, perhaps the best known being sugar maple (Acer saccharum) of eastern Canada and the northeastern United States. The Canadian flag displays a stylized maple leaf, and maple is Canada’s official arboreal emblem. Maples are not only important to Canada symbolically, they are also ecologically and economically significant.

Snow

The size of a snowflake is related to how far the snowflake has fallen from the sky and to how well colliding snow crystals stick to each other. The largest snowflakes are usually observed near 0° C because of the increased forces of adhesion at these temperatures.

Crustacean

Crustacean, shelled invertebrate with segmented body and limbs at some stage of its life, an exoskeleton and 2 pairs of antennae. The exoskeleton, a protective and supportive framework located outside the body, is periodically molted to allow for growth.

Solar Energy

The energy contained in sunlight is the source of life on Earth. Humans can harness it to generate power for our activities without producing harmful pollutants. There are many methods of converting solar energy into more readily usable forms of energy such as heat or electricity. The technologies we use to convert solar energy have a relatively small impact on the environment. However, they each have disadvantages that have kept them from being widely adopted.

In Canada, the use of solar energy to generate electricity and heat is growing quickly and is helping reduce pollution related to energy production. Despite Canada’s cold climate and high latitudes (which get less direct sunlight than mid-latitudes), solar power technologies are used in many places, from household rooftops to large power plants. The Canada Energy Regulator (formerly the National Energy Board) expects solar power to make up 3 per cent of Canada’s total electricity generation capacity by 2040.

Geological History

Fundamental to all ordering of events of the Earth's history is the principle of the positional relationships of rock and mineral bodies. For example, in any stratified rock sequence, younger rocks overlie older ones.
