Answer:
The answer is, cooler materials are highly dense, causing them to sink to the outer core or letter B
Explanation:
The matter that is closer to the surface of the Earth cools faster, causing it to sink back down into the core and the hotter, less dense material to take its place. The Earth’s rotation also influences convection. Cooler materials move from Earth’s mantle to the lithosphere. Cooler materials are highly dense, causing them to sink to the outer core. Warmer materials sink to the mantle because their density slowly decreases. Warmer materials have a high density, causing them to rise to Earth’s surface.
hope this helps!!
Answer:
my answer would be BB.The heliocentric model was finally accepted because it best explains solar eclipses.
Answer: C. Y and Z
Explanation:
First, it is necessary to understand the concept of escape velocity.
The <u>escape velocity</u> is the <em>minimum speed with which any object needs to be launched to move indefinitely away from a more massive body or system to which only the gravitational force links it.
</em>
In this sense, each planet and body of the solar system has an escape velocity with which if an object is launched, it can escape the gravitational attraction of that planet. In the case of Earth it is approximately 
.
Hence, from the given options, the objects whose speeds are closer to 
are Y and Z.
almost all the countries depend on agricultural and production of crops for their development. they have achieved alots of benefits which couldn't be discribed but due to competition among the countries for development . resources are being exploited haphazardly without focusing in the conservation of natural vegetation.
