Because of this, snakes that live in colder climates must hibernate through the winter. They will find burrows or caves and fall into a deep sleep until the weather warms up enough for them.
There are more than 2,700 species of snakes in the world. They live almost everywhere, in deserts, forests, oceans, streams, and lakes. Snakes live on the ground, in trees, and in water. There are a few areas where snakes do not live. They cannot survive in places where the ground stays frozen all year around, such as in the high mountainous regions, above the Arctic Circle and Antarctica. Some islands, including Ireland and New Zealand, do not have snakes at all.
Introduction
3.3. Biological Sciences Biology concerns living things, their appearance, different types of life, the scope of their similarities and differences, where they live and how they live. Living things are made of the same components as all other matter, involve the same kinds of transformations of energy and move using the same basic kinds of forces as described in chemistry and physics standards. Through the study of the diversity of life, students learn to understand how life has changed over a long period of time. This great variety of life forms continues to change even today as genetic instructions within cells are passed from generation to generation, yet the amazing integrity of most species remain.
3.5. Earth Sciences The dynamics of earth science include the studies of forces of nature that build the earth and wear down the earth. The understanding of these concepts uses principles from physical sciences, geography and mathematics.
