A type of rock that forms directly from precipitates of hot water is called a <u>hydrothermal</u> rock
What is a hydrothermal rock?
- Hydrothermal essentially means “hot water.”
- Hydrothermal rocks are those rocks whose minerals crystallized from hot water or whose minerals have been altered by hot water passing through them.
- Thus, these rocks are distinct from metamorphic rocks, which are created by solid‐state mineral transformations.
- In fact, many hydrothermal rocks (such as those that form from hot springs and geysers or crystallize as veins in cracks in other rocks) actually build up in layers, much as sedimentary rocks do.
- Veins result when hot water moves through cracks in the bedrock of the crust.
- Various minerals are precipitated on the sides of the crack as the temperatures decrease.
- The shape and orientation of the minerals depends on the temperature, pressure, and rate of flow.
- When all the available space in the crack has been filled with mineral deposits, the crack is sealed and the vein is complete.

It was a "social experiment" since, unlike in most other places, a new nation was created in a short time from the many people who came to the land (unlike for example in Europe, where people have lived in the same place for generations).
So people could start the organisation of the society almost "from scratch" rather than negotiate slowly what was already threre - and this was new, an "experiment".I think that the experiment is in a way still ongoing, but not as much as it was before. The challenges that the US faces today are more similar to those of other nations.
Answer:
Dominant inheritance means an abnormal gene from one parent can cause disease. This happens even when the matching gene from the other parent is normal. The abnormal gene dominates. This disease can also occur as a new condition in a child when neither parent has the abnormal gene.

Answer:
The first twenty years of Georgia history are referred to as Trustee Georgia because during that time a Board of Trustees governed the colony. England's King George signed a charter establishing the colony and creating its governing board on April 21, 1732.
<span>The colonist began smuggling goods during the 1760s because
they were heavily taxed by the British. The
stamp Act affected both colonist and British merchants alike. Also the British would not permit ships from
other countries to trade in America. The
Navigational Act prevented colonist to buy cheaper goods from other countries
and because of these unfair conditions, it light the fuse that led to the
American Revolution as the colonist desired to be free from British rule and
establish their own country.</span>
