Answer:
Explanation:
These lines, more often called borders, are created by people to separate areas governed by different groups. Sometimes, political boundaries follow physical boundaries, but most of the time you can't see them. Most maps show political boundaries. Political boundaries change over time through wars, treaties, and trade
South of the Alps lies the Apennine Peninsula.
Explanation:
The Alps are the largest mountain range on European soil. It is still up for debate are they the highest mountains in Europe or not, as there are still debates about the border of Europe and Asia in the Caucasus, where there are higher mountains than the Alps. This mountain range has been formed by the Alpine orogenesis, which has been triggered by the movement of Africa toward Europe. These mountains are considered to be young mountains, and they are still growing in area and height.
- The Alps are a natural barrier between Central and Western Europe north of them, and the Apennine Peninsula south of them.
- The Appennine Peninsula has its northern border totally surrounded by the Alps, which has led to the development of a unique culture, but also served as a good defense mechanism in the past.
- There are three countries located on the Apennine Peninsula, with Italy dominating almost all of it, and San Marino and Vatican occupying very small areas.

A granite can be transformed from an igneous rock to a sedimentary rock and then to a metamorphic rock or the sedimentary rock can be transformed back into granite again by metamorphism. First of all, a granite often occurs in mountains and is susceptible to weathering and erosion.. Weathering such as argillic weathering can help break t he rock down to its constituent minerals which are mostly quartz, orthoclase feldspar and biotite mica. This then gets washed down into the rivers and thence to the coast and gets deposited in a marine environment as part of a delta or alluvial fan, in the form of sand, silt, clay and gravel. As this sediment becomes compacted, it turns into rocks like sandstone, siltstone etc. With deeper burial and the addition of heat and pressure these rocks get converted into such metamorphic rocks as quartzites, slates and phyllites, etc. I have seen a meta sandstone grade into a granite in the Canadian Shield so granite can then form from metamorphic processes as well as igneous processes.
An estuary is where salt water and fresh water meet. Estuaries are usually found at the edge of the coast, where the ocean water, or salty water, meets river, lake, any fresh water source, water.
A tributary is something completely different. It is a, usually smaller than the main river or lake, river/stream stemming off a bigger river or lake, or flowing into that river or lake.
