Tundra climate is probably the most biomes that are influenced by the climate. Four principal factors that affect Tundra climate are the solar radiation‚ the temperature‚ and precipitation as well as air pressure. Solar radiation is very weak in Arctic or Antarctic tundra which is why polar tundra are often covered in the snow compared to other tundra around the world. However‚ in summer‚ there is more solar radiation which gets the temperature to rise. Alpine tundra zone gets more solar radiation

in a species or a population‚ the gene pool. Domestication and plant breeding lead to a loss of genetic variety‚ hence the importance of “gene banks” Habitat diversity: The number of different habitats per unit area that a particular ecosystem or biome contains. It is associated with the variety of niches that may be exploited by different species. Conservation of habitat diversity usually leads to the conservation of species and genetic diversity Fitness: The ability for an individual to survive

is breaking them into their two categories. The Jovian planets (Jupiter‚ Saturn‚ Uranus‚ Neptune) are primarily composed of gas and are the outer 4 planets in our solar system. The Terrestrial planets (Mars‚ Earth‚ Mercury‚ Venus) are mostly rock and metal and are the four planets closest to the sun. Since the Terrestrial planets are made of rock and metal‚ their surfaces are

The rings of Saturn and Uranus may seem similar‚ but they are actually very different. The 2 planets ring systems differ mainly in their composition‚ size‚ and number. Saturn has 7 main ring groups that are made up of many other smaller rings. The groups are generally thicker in diameter but can vary. The rings themselves are composed of mainly icy particles. On the other hand‚ Uranus’ rings are broken into 9 sections and are generally thinner in diameter. Uranus’ rings are composed of both icy particles

One of the most common unanswered questions scientists find themselves asking is "Is there life on other planets?" Since the first famously documented UFO sighting in 1947‚ the idea of extra-terrestrial life has been debated almost non-stop. The subject has inspired many TV programs‚ such as The X-Files‚ and films (Mars Attacks‚ Independence Day‚ and the Men in Black films to name but a few). Scientists have come up with many new ideas and ways of trying to either prove or disprove the existence

life. The carbon cycle is the exchange of carbon among three reservoirs or storage places: the land‚ the oceans‚ and the atmosphere The atmosphere has the least amount of carbon‚ followed by the land with it plants and animals‚ also called the terrestrial biosphere and the ocean being the largest carbon reservoir. The carbon cycle is important as carbon-containing gases such as carbon dioxide affects and regulates the earth’s climate. It is also vital during the processes photosynthesis and respiration

The effects of extra terrestrial sightings can have an adverse effect on people if influenced the wrong way. No solid proof has shown that UFO ’s are real‚ but many sightings cannot be proven otherwise. The media‚ stories‚ or one ’s own experience may often influence what one believes. The government once stated that they had captured extra terrestrials.

forms present during this period‚ the events surrounding the mass extinction that signified its end remains a mystery today. The end-Permian mass extinction is regarded as the largest mass extinction event in the earth’s history‚ with marine and terrestrial life declining by 95% and 75% respectively (Shen et al. 2014). While clear that life on earth was greatly affected‚ many scientists are conflicted on the cause/causes of the extinction event.
