Extrusive igneous rocks are formed by cooling lava. Since
the temperature gradient between lava and Earth’s atmosphere is very big,
cooling is very rapid. The second option is deemed true, which also means the
third option is false. Foliations occur only in metamorphic rocks, deeming the
forth option false. Since extrusive igneous rocks are formed at the surface of
the Earth, there would be no confining pressure, which means the first option
is false.
Most of the population of the world is concentrated on the continental margins, or more specifically, along the coastlines. This is due to multiple factors, some of which are:
- Climate;
The climate in the coastal regions is usually much more pleasant that the climate deeper into the mainland, so naturally the people preferred to live where it is more pleasant.
- Arable land;
In close proximity to the coastline there's usually nice fertile soil, so it is very suitable for production of food, thus managing to sustain yourself.
- Economy;
The coastal regions, in lots of cases, are well suited for building ports, and that makes them excellent places from where trade can take place, so it strengthens the economy of these places.
metamorphic rock are the rock which are formed when igneous rock and sedimentary rock change from one form to another form due to more heat and pressure. long time exposure of heat and pressure on the sedimentary rock and igneous rock changes them from one form to another form and metamorphic rocks get form

To help understand trends, identify patterns, or assist in explaining a particular phenomenon.
Answer:
The answer is below
Explanation:
A kite is a quadrilateral (has four sides and four angles) with two pairs of congruent adjacent sides.
From the image we can see that one pair of congruent side has be formed with a length of 30 feet. Therefore the amount of rope that has been used is 60 feet and 40 feet (100 - 60) of rope would be remaining to complete the kite. Hence 40 feet of rope would be used to make the other pair of adjacent side.
This means that the remaining pair of adjacent side would be 20 feet each so that all the roe would be used.
