Weather and Climate

The difference between weather and climate is a measure of time. Weather is what conditions of the atmosphere are over a short period of time, and climate is how the atmosphere “behaves” over relatively long periods of time. Weather is basically the way the atmosphere is behaving, mainly with respect to its effects upon life and human activities. The …

Atmospheric Sciences

Atmospheric sciences is an “umbrella term” for the study of the atmosphere, its processes, the effects other systems have on the atmosphere, and the effects of the atmosphere on these other systems. Weather and Climate International Weather Symbols Climatic Region Map Wind Chill

Atmosphere Index

The atmosphere is a layer of gases which surrounds the entire Earth. It consists mainly of Nitrogen, Oxygen, as well as a few other gaseous elements. The purpose of this “layer” around the Earth is to prevent excessive amounts of radiation from reaching the Earth, thereby allowing we, as animals / planets, to survive. The atmosphere is …

Plant Morphology

Plant morphology or phytomorphology is the study of the physical form and external structure of plants. This usually considered distinct from plant anatomy, which is the study of the internal structure of plants, especially at the microcopic level. Plant morphology is useful in the visual identification of plants.

Dendrology is the study of woody plants. These include trees: erect woody plants usually with one central trunk; shrubs: erect plants with numerous woody stems; and vines: woody plants that require an erect substrate for support. Dendrology tends to focus on economically useful woody plants, their identification and horticultural or silvicultural properties. Dendrology is often …

Zoology is the study of animal life. Zoology focuses on the evolution of the animal kingdom, comparing the anatomy, physiology, reproduction and behavior of animal groups. Zoologists are interested in the biology of particular groups of animals, the structure and function of animal bodies, and studying how new animals are formed and how their characteristics are passed on from …
