Snake Species in Canada

A snake is a long, slender reptile of the suborder Serpentes, within the order Squamata (which also includes lizards). There are 25 species of snake currently found in Canada. In addition, one species, the timber rattlesnake, and one subspecies, the Pacific gophersnake, are extirpated. This means that, while they continue to live in other parts of their range, they are no longer found in Canada. Snake species in Canada belong to one of three taxonomic families: Boidae, Viperidae or Colubridae. Most species live in the southern part of the country; however, the common gartersnake can be found as far north as the 60th parallel, near Fort Smith, Northwest Territories.

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.

Soil

Soil is the thin, fragile surface layer of Earth. It is a dynamic, loose and porous body of variable thickness (between a few centimetres and a few metres). Soil is formed by continuous transformations of rock or deposit through physical, chemical and biological processes. It is one of the two main components of Earth — the other being oceans — in which life is particularly active. Soil is the source and site of many human activities, and human life greatly depends on it. In Canada, agricultural, environmental and natural-resource scientists are at the forefront of research on soil.
