At the divergent plate boundaries new oceanic lithosphere is formed in the gaps of magma coming up from the mantle. The magma coming up forms mid-ocean ridges. They form along mountain chains that are marked as boundaries between diverging plates.
Answer:
They are youngest close to the ridges,
Explanation:
At the ocean ridges, there is divergence at their margins.
Therefore, new materials upwell from the mantle below to the surface.
- The basaltic materials cools and solidifies at the margin.
- This action forces the old lithosphere backwards as the plate pulls away.
- At the margin of the ridge, the rocks are younger.
- Away from the margin, the crust begins to grow older.
So, at the margin the age of the rocks are more younger than those away from the margin.
Due to two factors..
The first factor is the placement of Europe in relation to latitude lines.
Up north is bound to be more cold than most places down south near the Mediterranean sea. (Which is closer to the equator)
The second factor is the physical geography of the region. Ranging from mountain ranges like the Alps and the Urals to the flat planes of much of mid Europe. The weather interacts with these regions and determines the climates making up much of the continent. (Only takes a rudimentary understanding of basic earth science and geography to understand that. If you have more questions pertaining to the subject, pm me.)
Answer:
What should be <u>TRUE</u> of the island of <em>Hawaii</em> :
- Scientists in search of ongoing speciation events are more likely to find them here than on the other six large islands.
- Its species should be more closely related to those of nearer islands than to those of farther islands.
- It should have a rich fossil record of terrestrial organisms.
Explanation:
In cases of <em>geographic isolation</em>, and subsequent speciation, produced by dispersal and colonization phenomena we can find the island of Hawaii. Adaptation to these environments can be the trigger for divergence. The <em>large number of species</em> in this archipelago, more than 500, seems to have emerged through<em> migration</em> and diversification. Many of these are endemic to a nearby island, and the subsequent<em> evolutionary divergence.</em>
The volcanic islands, which have never been in contact with the continent, are especially<u> rich in endemic species; </u>the species that inhabit them are descendants of those who arrived in times past and <u>were able to adapt.</u>
Almost ninety years ago, in the south of the island of Hawaii, they revealed some <u>bones </u>that turned out to be the<u> first bird fossils discovered i</u>n the archipelago. The bones were under a flow of prehistoric lava and on a bed of volcanic ash.
In short, the Island of Hawaii is of great interest to scientists and there are always new developments buried years ago by volcanic activity.
Answer:
1-Civilization describes a complex way of life that came about as people began to develop networks of urban settlements. The earliest civilizations developed between 4000 and 3000 BCE, when the rise of agriculture and trade allowed people to have surplus food and economic stability
2-The scope of Civilization is larger than most other games. The game begins in 4000 BC, before the Bronze Age, and can last through to AD 2100 (on the easiest setting) with Space Age and "future technologies".
3-Civilizations first appeared in Mesopotamia (what is now Iraq) and later in Egypt.
4-Gods of Mesopotamia - 3200 BC, Home of the First Written Evidence of Religion.
5-From the collapse of ancient Rome to the fall of the Mayan empire, evidence from archaeology suggests that five factors have almost invariably been involved in the loss of civilizations: uncontrollable population movements; new epidemic diseases; failing states leading to increased warfare; collapse of trade routes
6- Most civilizations have agriculture, and a system of government like monarchs or elections. They speak a common language, and usually have a religion of some kind. They teach their young the knowledge they need. All civilizations since the Sumerians and the Egyptians have some kind of writing.
