According to Khanna the lines that are important to North America are the ones that are based on connectivity.
<h3>What does Khanna say about continental lines?</h3>
This author referred to this lines as useless lines that divided territories in the world.

Answer:
Ferrous (Fe²⁺) and magnesium cation (Mg²⁺).
Explanation:
The olivine mineral is a type of orthosilicate, which is generally yellow to yellow-green in color. It is the main component of the upper mantle of the Earth, which can be found in igneous and metamorphic rocks.
The olivine mineral exists in the form of Mg₂SiO₄, Fe₂SiO₄, or (Mg,Fe)₂SiO₄.
<u>This silicate consists of two divalent cations, ferrous (Fe²⁺) and magnesium cation (Mg²⁺).</u>
Answer:
C. Turbine
Explanation:
Most power-generation technologies use a form of turbine to create electricity. The turbine is forced to spin because of an external force applied to its blades, and that movement against a fixed generator created electricity.
In a gas or steam plant, the gases force the movement of the turbine.
In water-based plants, it's the water pushing the blades (like in a dam).
In a wind turbine, it's the wind pushing the blades.
And so on.
<span>Climatic Variation of the Himalayas
</span> The Himalayan region mainly experiences two season winter and summer. The average summer temperature in the southern foothills is about 30 degree Celsius and the average winter temperature is around 18 degree Celsius. In the middle Himalayan valleys the average summer temperature is around 25 degree Celsius while the winters are really cold. And on the higher region of the middle Himalayas the summer temperature is recorded at around 15 to 18 degree Celsius while the winters are below freezing point. The climatic condition at region above 4880 m is below freezing point and it is permanently covered with snow. During the winter the snowfall is really heavy while the summers are much more mild and soothing. The Himalayan Alpine climate varies according to the altitude. The more the height the more cooler the temperature gets here. The climatic condition changes very quickly in the Himalayan region due to change in the altitude. The climate here is very unpredictable and dangerous too.
