Volcanoes play an important role in creating land since they are the sources of magma, which once above ground normally cools to create new land. In the ocean, this land normally forms at divergent and convergent boundaries or hot spots. At divergent boundaries (where two plates move apart), magma constantly erupts along a trench deep below the ocean's surface. This magma rarely piles upward and instead is pushed to both sides of the trench. This is how new seafloor forms. Convergent boundaries can create island arcs like Indonesia as magma erupts bit by bit. Hot spots occur in the middle of plates. They are instances where the mantle pierces through the crust and begins to erupt directly onto to seafloor. Over time, these eruptions will pile up and create underwater volcanoes until they potentially make it above sea level, thereby forming an island. This is how Hawaii was and continues to be formed.
The land area of Australia is about the same size as the land area of the continental United States. The correct option among all the options given in the question is option "D". Australia is the sixth largest country in the world in respect to its size. Russia, Canada, Brazil, USA and China have a larger area than the continent of Australia.
We know that the poles had changed positions in the past, because of the arrangement of the crystals in the rocks made out of metal. The crystals of the metals act like the needle of the compass when the rock is cooling off and forming, they turn into the direction of the strongest magnetic field on the Earth, which is the North Pole. So by studying the rocks that are made out of metals and see the crystals arrangement and also estimate the age of the rocks, the scientist can precisely tell how has the North Pole been moving throughout time.
Answer:
1. arid
2. semiarid
3. Mediterranean
Explanation:
The Southwestern states of Arizona and New Mexico are characterized by the following climates arid, semi-arid and Mediterranean.
This is evident where arid to semi-arid climates are found in places like Nevada, Arizona, West Texas, and the and so on where there are desert lands and mountains.
The Mediterranean climates in the region of southwestern are found in places like Wyoming, where there is a form of desert land but capable of experiencing high cold temperatures at night during winter.
Geographic variation was the study or examination that living things which are relatively similar are different because of their habitat and geography was dissimilar. Comparable organisms parted ways by physical features and global positioning.
It depends on the position of the species a cline can happen. This can relate to a specific one of two or more substitute forms of a genetic factor that arise by transformation and are found at the same place on a chromosome which will assist in surviving of a different but reachable geographic location.
