Answer:
Scalar quantity
Explanation:
Scalar quantities give a magnitude, while vector quantities give a magnitude and a direction. The answer will be a measurement that does not change, regardless of the direction of action. Displacement is a measure of length in a given direction; distance is the scalar version of displacement. hence length is scalar quantity
Answer:
Global warming can lead to more drought-resistant crops, increase the growth of some crops and improve the climate of countries with extreme climates.
Explanation:
Global warming is one of the great villains of modern society, as it is the main precursor of climate change that causes so much damage to living beings. However, some researches prove that global warming has had some advantages, which even not justifying its existence, should be disclosed.
Global warming, caused by the emission of greenhouse gases released by human activities, allows the earth's temperatures to rise. This allows some crops made up of plants that need high temperature to develop better, to grow faster. Furthermore, these plantations can develop resistance to drought and high temperature.
In addition, the increase in global temperature can help countries that suffer from extreme cold during winter such as Russia, Norway, Tajikistan, Canada, among others.
Banded iron formations are composed of alternating light and dark bands of chert.
<h3>
What is chert?</h3>
- Banded iron formations are made up of alternating light and dark chert bands.
- Chert is a sedimentary rock that forms in a variety of ways and is almost entirely composed of silica (SiO 2).
- When the siliceous skeletons of marine plankton are dissolved during diagenesis, silica precipitates from the resulting solution, biochemical chert is formed.
- Chert layers, which occur as irregular beds or rounded nodules within limestone formations, are common in eastern Kansas.
- Because it is harder than limestone, chert is more resistant to erosion.
- The Flint Hills' chert-topped hills are the result of the landscape's uneven erosion.
Therefore, banded iron formations are composed of alternating light and dark bands of chert.
