Minerals that grow as crystals in cooling lava can become magnetized if they contain iron.
Igneous rocks are composed of minerals that crystallise at a variety of different temperatures. This explains how a cooling magma could contain some crystals while still being primarily liquid. The Bowen reaction series is the pattern of mineral crystallisation from a magma.
Individual plagioclase crystals can be zoned from more sodium-rich around the exterior to calcium-rich in the centre when cooling occurs reasonably quickly. Because it controls how long the reaction can last before all the silica is consumed, the initial magma's composition is crucial to the crystallisation of magma.

Answer:
- It can change over time for certain kinds of loans.
- It is the interest charged each year for a loan.
- It can be reduced to reflect the borrower’s credit history.
Explanation:
The annual percentage rate is the amount of interest that is charged to the loanee for borrowing the loan and it is different for different types of loans such that with some kinds it can change overtime based on certain factors such as inflation.
Percentage rates are a reflection of the riskiness of the borrower so if the borrower has a good credit history, the rate can be reduced to show that the borrower is not too risky.

The majority of neandertal fossils been found in <u>Europe </u>where they have been most studied.
More about the neandertals:
The Neanderthals have undergone extensive evolutionary change. Around 430,000 years have passed since the earliest fossils that resemble Neanderthals were discovered. The earliest Neanderthals are thought to have existed between 130,000 and 40,000 years ago, beyond which no physical proof of them can be found.
In contrast to modern humans, who have a more globular skull, Neanderthals had a long, low head with a distinctively noticeable brow ridge above their eyes.
Their face also stood out. A very large, wide nose dominated the forward-protruding middle portion of the face. They would have breathed in warm, moist air thanks to the high internal volume of their noses. The size of their front teeth and the scratch scars on them indicate that they were frequently employed as a third hand when preparing food and other materials.
