Explanation:
we depend on them for drinking water
they are home to lots of species
they are the source of our irrigation for agriculture
All of the above are reasons why freshwater biomes are important.
The reddish-orange colour of weathering of volcanic ash is most likely due to its iron sulfide content which oxidizes to iron oxide so that limonite is yellow and hematite is red and in ash since it is such fine grained material it weathers more rapidly because it has a large surface area.
Answer:
24
Explanation:
Given parameters:
Atomic number = 24
Mass number = 52
Unknown:
Number of electrons in the uncharged atom of chromium = ?
Solution:
In an uncharged atom of chromium, the number of protons and electrons are the same.
Once we can find the number protons, we can simply equate it to the number of electrons.
- Atomic number is the number of protons in an atom.
- Therefore, since the atomic number is 24, the number of protons likewise is 24;
Number of electrons is 24
Explanation:
Catastrophism is the theory that the Earth has largely been shaped by sudden, short-lived, violent events, possibly worldwide in scope, this contrast with Uniformitarianism that suggests that the landscape developed over long periods of time through a variety of slow geologic and geomorphic processes.
To meaningfully study the past, we must assume the same or similar mechanisms operated then as now, following this idea we conclude that uniformitarianism is a more logical theory, <em>geologists then consider periodic catastrophe (volcanic eruptions, earthquakes, meteorite impacts, and storm deposits) is one of those processes uniformitarianism suggests.</em>
