Answer:
B) a slow process
Explanation: its just like the rock cycle or any change to the Earth's surface :)
Answer:
Igneous and sedimentary rock types led to the formation of terranes as these has occurred during the time of oceanic basin closure.
Explanation:
- The deposition of sedimentary and volcanic rocks and some still unconsolidated sediments are deposited in the region which is related to the terrane accelerated events.
- And terrane acceleration is tectonostratigraphic fragmentation of crustal matter which is often broken from the crustal plate and is identified as a fault.
- Their activity is reflected in igneous rocks when the source material was eroded from the sediments. The youngest ages are constrained by the deposition of schists with active volcanism at its source with the youngest zircon crystallization.
- Diverse types of acceleration may be found in oceanic plateaus, island, and arcs and composite terranes of stratified, disrupted, metamorphic and composite.
Answer:
Explanation:
The Northeast is characterized by a fairly diverse climate, with bitterly cold winters and semi-humid summers, especially to the south.
The frontiers when taken into consideration, maps which establishes the European frontiers were seen to appear from the 18th century only and not prior to that.
<u>Explanation:
</u>
The ideology of formation of state or state boundary were emerged with the period of 17th century and even mid of 16th century witnessed it. The establishment of frontier though started with 18th century only.
The different topographical features were considered to describe the fronts such as the rivers, mountains. And, even the landmarks such as forts or towers were considered as the border distinction.
Answer:
b. An island 30 hectares in size that is 10 kilometers off the coast of the mainland
Explanation:
- Based on the theory of the island biography the highest number of the species would be found in the islands that have to be an island of the 30 hectares and is separate from the mainland coasts at a distance of the 10 km. And various factors affect the species diversity and richness of the isolated systems with a specific relationship to the oceanic islands.
