Answer:
Cleavage of a mineral is defined as the direction along which the mineral breaks over the flat mineral surface. It is directly dependent on the mineral's crystallographic structure.
Slaty cleavage refers to the cleavage that is commonly found in the low grade metamorphic rock slate. Here, the fine grained minerals are so closely spaced and the lines of weakness are all parallel to each other, that allows the minerals to break in fine and thin layers. During the time of formation of slate, the smaller fractures are formed due to the increasing pressure. When groundwater moves through these fractures it forms a weak zone due to which these slaty cleavage forms.
When the rocks undergoes deformation and changes in the pressure and temperature condition then the cleavages are formed on the mineral's surface. The calcite contains rhombohedral cleavage are considered to be the perfect cleavage. Whereas the cleavage in amphibole is uneven and comprised of two directions that intersect each other at 56° and 124°.

Answer: 5am on Sunday, May 3rd.
Explanation:
Plane left at 12pm and takes 17 hours.
Add 12 and 17:
= 12 + 17
= 29
There are 24 hours in a day. The number of hours into the next day is therefore:
= 29 - 24
= 5 hours
If the plan arrives 5 hours into the next day, that would mean that it arrived at 5am. Date of the next day is May 3rd, a Sunday.
