Plate Tectonics

Plate tectonics is the theory proposing that Earth’s outer rocky shell is divided into seven major and several smaller rigid plates. Forces generated by heat losses from the planet’s interior constantly move the plates about. Plate movements, ongoing over millions of years (see Geological History), open and close ocean basins, generate volcanoes, raise mountains, facilitate accumulation of mineral and petroleum deposits, and influence evolution and climate change. Friction between plates prevents steady motion and stores energy that is released in sudden movements, causing earthquakes.

Floods in Canada

Floods are primarily caused by naturally occurring changes in the height of rivers, lakes and oceans. According to Public Safety Canada, floods are the most common natural hazard in the country and among the costliest. Historic floods have occurred across Canada, with many of the worst happening on major river systems that pass through populated areas. Scientists predict that flooding linked to the impacts of climate change will increase as the 21st century progresses, particularly in coastal areas of the country.

Endangered Plants in Canada

A species is endangered if there are threats to its survival. Plants are put at risk for several reasons, including: climate change and the loss of natural habitat to cities, agriculture and industry. In Canada, these activities threaten entire natural ecosystems, such as older forests and Prairie grasslands. As of 2021, 250 plant species are at risk in Canada, according to the Committee on the Status of Endangered Wildlife in Canada. In addition, four are extirpated and one is extinct. The committee’s definition of a wildlife species includes taxonomic categories as well as geographically distinct populations. For example, the bent spike-rush (Eleocharis geniculate) is included on the list of at risk plant species twice, as there are two different populations, one in British Columbia and one in Ontario, facing different threats to their survival. (See also Endangered Animals in Canada.)
