<span>Extreme temperature and bedrocks
Tundra and desert both have shallow soil profiles because of the extreme temperatures and the bedrocks it has. In the case of tundra, it has extreme cold temperature and the soil were covered in ice in long periods of time. Because of this, the plants were unable to get water from the bedrocks resulting in plants dying. In the desert, however, it has extreme hot temperature making the plants unable to survuve due to lack of water in the environment and in the bedrocks. The plants that can only survive in this temperature are the plants that has the ability to store water in their system.</span>
Insects<span>, which are a type of </span>arthropod<span>, are easily the most numerous group of multicellular </span>organisms<span> on the planet, with about a million species identified so far. The title of heaviest insect in the world has many rivals, the most frequently crowned of which is the </span>larval stage<span> of the </span>goliath beetle<span>, </span>Goliathus goliatus<span>, the top size of which is at least 115 g (4.1 oz) and 11.5 cm (4.5 in). The largest confirmed weight of an adult insect is 71 g (2.5 oz) for a </span>giant weta<span>, </span>Deinacrida heteracantha,[1]<span> although it is likely one of the </span>elephant beetles<span>, </span>Megasoma elephas<span> and </span>Megasoma actaeon<span>, or </span>goliath beetles, both of which can commonly exceed 50 g (1.8 oz) and 10 cm (3.9 in), can reach a higher weight.<span>[1]</span>
Answer:
B. Protect us from harmful ultraviolet Radiation.
Explanation:
I did this in 6th grade. The ozone layer contains a high concentration of ozone, which absorbs most of the ultraviolet radiation reaching the earth from the sun.
Answer:
Due to mixing of particles present in the upper layer of limestone with sandstone during deposition.
Explanation:
The parent layer was limestone layer which is older than sandstone layer. This sandstone layer spreads on the limestone layer because of wind. The wind moves these sandstone from other region and their deposition occurs on the limestone layer. During deposition of sandstone, some particles of limestone which are present at the surface mixes with the sandstone so that's why in sandstone layer, small and weathered pieces of limestone are present.
