Answer:
The lithosphere-asthenosphere boundary
Explanation:
because is conventionally taken at the 1300 °C isotherm. Below this temperature (closer to the surface) the mantle behaves rigidly; above this temperature (deeper below the surface) it acts in a ductile fashion.
Answer:
The answer is 5.1852 cm/yr
.
Explanation:
In order to calculate the full seafloor spreading rate in cm/yr, we have to first calculate the half-spreading rate which can be done by simply dividing the given distance (in cm) by time (yr); after calculating the half-spreading rate, we will double it and get the full seafloor spreading rate, thus:
Distance = 3,500 km = 3,500 × 100,000 cm = 350,000,000 cm
Time = 135,000,000 years
The half-spreading rate = distance ÷ time = 350,000,000 ÷ 135,000,000 = 2.5926 cm/yr
.
Therefore, the full seafloor spreading rate = 2.5926 cm/yr × 2 = 5.1852 cm/yr.
This is a topic that comes up in politics a lot. The first slot is nation and the second is state. Despite them often appearing side by side, it is important to distinguish between the 2. For some people to be a nation, there needs to be a sense of communality and cultural elements. Nations can exist without states (having territorial control of the land they live in) just like natives in various parts of the world. Also, states can exist without a specified nation living there; for example there are multicultural states or states with very few inhabitants that can hardly call themselves a nation.
Andorra because all the rest end in -ia
Answer:
Cold, dry
Explanation:
Humid air is often more associated with tropical climates, and we can assume from "polar" that the answer would be cold.
