Light colored igneous rock is called felsic, it is high in quartz, muscovite mica, and orthoclase feldspar content. Dark colored igneous rock is called mafic, and contains a lesser amount of silica along with olivine, pyroxene, amphibole, biotite mica, and plagioclase feldspa
<span>Light coloured igneous rocks (felsic) tend to have greater silica and aluminum content and a lower iron and magnesium content than dark (mafic) rocks.</span>
The sediments located in Heinrich layers contain almost exclusively<u> </u><u>ice</u><u>-</u><u>rafted</u><u> </u><u>detritus</u><u>, known as </u><u>IRD</u><u>.</u>
Heinrich layers are layers of sediment in the North Atlantic. These sediments have consist of high amounts of debris in Foraminiferida shells brought by ice. This composition explains how these layers function as a historical record of major ice releases.
These layers are formed from huge releases of ice of the Hudson Strait ice stream. The North Atlantic cores of sediment found in these layers are badly sorted and lack almost any foraminifera, being composed of primarily ice-rafted detritus (IRD).
These IRDs are described as sediments of no particular size that are carried by floating ice until they are introduced into the water and mix into the environment. This Ice carries debris located within it in the way a raft would carry a person, by allowing it to float on the surface of the water

Uneven distribution of wealth, increased population leads to crowded urban areas which could be unsanitary, immigration can cause cultural conflicts
Answer:
City B of Northern Hemisphere
Explanation:
The major difference between the southern and northern hemisphere is that the southern hemisphere has more water than land. In that case, water heats up and cools faster in Southern hemisphere.
Whereas, in the northern hemisphere there are more lands than water, therefore, land heats up and cool faster. Land absorbs heats faster and releases same faster. 90% of world population lives in the northern hemisphere
The only division between the Southern and Northern hemisphere is the equator.
Base of above explained, there are much temperature variations in the northern hemisphere than in the southern hemisphere, because of large landmass and physical variation of various land forms. Northern hemisphere experiences extreme climate
City B in the northern hemisphere will have largest annual temperaure.
