Enceladus, one of Saturn's moons of only
about 314 miles in diameter hides in its entrails an ocean of liquid water that
is rich in organic molecules, making it one of the places where it is most
likely to find some form of extraterrestrial life.
Europa is a strange
shaped moon of Jupiter with a large number of intersecting lines. Models
from the interior of Europe show that under a thin crust of 5 km (3 miles) of
water ice, Europa can have oceans with 50 km (30 miles) of depth or more. The
visible marks of Europa could be the result of a global expansion where the
crust could have been fractured, filled with water and frozen.
Explanation:
As the two plates move away from each other in a divergent boundary, the magma from the mantle beneath rises to replace the void created. The magma then cools into a new crust. Before the magma cools, the iron minerals align themselves with the magnetic fields of the earth due to their ferromagnetic properties. These cause the rocks after they are cooled to seem to have bands.
Due to magnetic reversals of the earth's magnetic fields (i.e change in magnetic north and south poles) over several hundred thousand years, these bands will orient differently depending on the then earth magnetic polarity when the magma was cooling.

Answer:
The temperature of the Sun's middle most layer is 6,000 degrees Celsius to 20,000 degrees Celsius.
Explanation:
- The sun is basically divided into inner and outer layer.
- The inner layer consists of Core, Radiative Zone and Convection Zone.
- The outer layer has Photosphere, chromosphere, transition region and corona.
- The chromosphere is the middle layer that can vary its temperature 6,000 degrees Celsius to 20,000 degrees.
- For most reason the temperature of chromosphere can be taken around 7700 degree Celsius but it varies.
Answer:
why would scientists conduct investigations on a newly discovered alternative fuel?
to confirm that the alternative fuel is cleaner than fuels currently used
Explanation:
As an alternative fuel, it must be validated whether it is better than the one currently in use
