Australia is an island country, and besides the big main island and Tasmania, it has 12,000 islands plus in its territory. Since it doesn't have any land borders, its borderline is actually the sum of all coastlines of all islands in its territory, and that accounts for 70,000 km.
New South Wales is the biggest state in the country, and it occupies 10% of its total land mass. Its border is 4,635 km, which means that it accounts for 6.62% of the total borderline of Australia.
Hi!
The majority of Earth is covered in water. So, we can immediately eliminate A and B.
After looking at the statistics, the United States Geological Survey has determined 71% of Earth's surface is covered by water!
Hopefully, this helps! =)
Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock.
<u>Explanation:</u>
The metamorphic rocks can be identified in some of the following ways. Some of them are rocks changed by the ocean or in the ocean will have salt in them. They are also identified by the amount of water and other minerals found in them. Look at the way the grain are formed.
Metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock. The parent rock can be either sedimentary, igneous, or even another metamorphic rock. The word "metamorphic" comes from Greek and means "To Change Form".
Reduce use of fossil fuels in factories and other places as a source of energy and attempt to replace the use of fossil fuels with cleaner sources of energy like "Wind energy" and "Solar energy"

Volcano Develops when one plate slides under another
Subduction zone Where oceanic crust collides with continental crust
Continental drift Moving plates
Magma Made from melting plates
A volcano is a igneous feature that forms on the surface when lava cools and solidifies. When a plate slides under another, the molten magma formed by the melting of plates reaches the surface to form volcanic structures.
Where oceanic crust collides with continental crust, a subduction zone is formed. The denser oceanic crust slides beneath the less dense continental crust.
Drifting continents are as a result of moving plate.
