Gas particles spread out to fill a container evenly, unlike solids and liquids. The particles move very fast and collide into one another, causing them to diffuse, or spread out, until they are evenly distributed throughout the volume of the container.
Navigable rivers and natural harbors was the geographic feature that contributed most to the settlement of colonies along the atlantic coast. The natural harbor is a body of water sheltered by natural barriers which is well deep to provide a good and a safe anchorage place which permit the transfer of cargo and passengers between the ships and the shore.
Answer: Partial melting
Explanation: Partial melting occurs when the temperature is high enough to melt some of the materials that make up a rock but not all. This happens because a rock is not made up of a single material but different materials which have different melting points.
As the molten or melted rock cools down it crystallizes in a process known as fractional crystallization and this is how igneous rocks are formed.
