Answer:
Climate Change Some of the biggest human migrations coincided with major changes in climate, according to a new analysis. Researchers say early humans set out in search of climates where more food was available. And some populations stayed put in certain locations because barriers like glaciers blocked their progress
Explanation:
<span>Rocks in earth's mantle and crust melt due to extreme temperatures and turn into magma.
Hot magma erupts as lava above earth's surface during a volcanic eruption.
Being exposed to a cooler temperature, the lava starts cooling down quickly.
The lava solidifies into a rock formation with a fine-grained or smooth surface.</span>
You have both questions right. Madagascar is an island because it's surrounded by water and culture is a learned away of living

Answer:
13, 320km
Explanation:
Step 1:
Measuring distance = differences in latitude
If the latitudes are in the same hemisphere subtract e.g. North and North, but if the latitudes are in different hemispheres then you add.
To find the distance between Town A and B, since they are in different latitudes( North and South), you subtract.
distance=(latitude+latitude)×111 km
= 50°+70°
=120°
Step 2: convert to km
Since 1°=111 km
∴ 111 km×120°
= 13,320 km
Hope this helps!!
