Answer: 
Explanation:
The Tropic of Cancer is one of the parallels (imaginary line around the Earth parallel to the equator) located in the northern hemisphere (currently its latitude is 
).
It is called "Cancer" because a long time ago, when the summer solstice occurred in the northern hemisphere (on June 20th or 21st), the Sun was in the constellation Cancer (the crab).
Now, if we were just in the North Pole, Polaris would by exactly over our heads (
over the horizon), but as we go south and find the Tropic of Cancer parallel, Polaris altitude will be approximately at an angle of over the horizon.
Hence, the altitude of Polaris measured by an observer at the Tropic of Cancer is .
Answer:
Magma are the hot molten materials that rises up towards the surface due to the increasing force from the depth. These magma when comes out to the surface then they are considered as lava.
The felsic lava are those in which the amount of silica and aluminium is very high. Due to this high silica content, the viscosity is high. The amount of silica present in magma or lava is directly proportional to the viscosity of magma or lava. The felsic lava due to its high viscosity flows sluggishly.
Whereas, the basic lava are those in which the silica content is significantly less. Iron (Fe) and Magnesium (Mg) is mostly present in this type of lava. As a result of which it flows easily without any difficulty.
This is the reason why felsic magma (lava) are more viscous compared to the mafic magma (lava).
From my perspective the crop is called "Poppy Crops".
Answer:
The Mediterranean climate zone.
Explanation:
(because this zone has mid to warm climate with seasonal rainfall in the winter months helps in the cultivation of grain crops like wheat and barley. Fruits like grapes, figs, walnuts and olives grow well in Mediterranean climate due to ideal soil types and dry summers.)
