<h3><u>Answer:</u> </h3>

Sometimes, some partly molten material rises towards the Earth's surface because either it gets added to the magma in the due course of the upward movement of magma and the magma doesn't get enough to melt it completely, or the material consists of elements with extremely high melting points.

<h3><u>Explanation:</u> </h3>

The magma carries molten material from the mantle towards the surface of the Earth.

In its course of rising up, sometimes some materials get added to it after it is just about to reach the Earth's surface.

Such material doesn't melt completely and reaches the surface in a partly molten form.

In other cases, the magma consists of elements with melting points above 1200° Celsius to 1300° Celsius.

Such materials sometimes reach the Earth's surface in a partly molten form.

Why did China launch out ''One Child Policy"?

zvonat [6]

Answer:

To try and contain the population growth.

Explanation:

In 1979, China's population growth was rapidly increasing. The government decided that this rate was too high, and passed the new law limiting each family to one child. You could actually pay to get out of this, but it ranged anywhere from $400 to $12,000 of a fine.

Hope this helped!
