Explain why global trade patterns are changing ttoday

gregori [183]

Answer:

Products and services previously available within one country are made available to new markets outside the country due to globalization. In addition, countries with positive relations between them are able to increasingly unify their economies through increased investment and trade.

Land echoes the arguments discussed previously: that free trade causes global inequalities, poor working conditions in many developing nations, job loss, and economic imbalance. But, free trade also leads to a "net transfers of labor time and natural resources between richer and poorer parts of the world

Shearing creates ______ faults, the San Andreas fault in California.

LiRa [457]

Shearing creates strike-slip faults that could possibly occur in the San Andreas Fault. Shearing is structural component of rock which refers to its texture and fault mechanics. Simply put, it is rock deformation that is caused by compressive stress. The study of shearing in rocks is related to structural geology.

Major events in trassic period

Yuri [45]

Answer:

Both the start and the end of the Triassic period is marked by some really interesting and important events. Major events were:

1. The major extinction event

2. Splitting of Pangaea

3. Expansion of animal life

4. Massive change and rejuvenation (appearance of Mammals)

Explanation:

The Triassic is a geologic period and system which took place 251 to 199 million years ago. The Triassic is the first and shortest period of the Mesozoic Era.

1. The major extinction event

Triassic period (and the Mesozoic era) didn’t exactly have such a glorious start. Violent volcanic eruptions, climate change, a fatal run-in with a comet/asteroid had set off the extinction of more than 90% of Earth’s species.

2. Splitting of Pangaea

By the start of the Triassic, Pangaea was already formed as a supercontinent shaped like a giant C. Almost as soon as the supercontinent formed, it started cracking. By the end of the Triassic period, 199 million years ago, tectonic forces had started splitting the supercontinent in two (Laurasia in the north and Gondwana in the south). The ocean called Tethys filled the “C” and that’s how the splitting of Pangaea started. Interesting thing to know is that earlier failed attempts of splitting formed rift valleys in North America and Africa that are today very rich in the best preserved fossils of Triassic life.

3. Expansion of animal life

There is a long list of animals that existed or first appeared in the Triassic period.

The oceans were filled with the coiled-shelled ammonites, mollusks, and sea urchins that survived the Permian extinction and were quickly diversifying. The first corals appeared! Although, some other reef-building organisms were already present.

Other amazing creatures were: dolphin-shaped ichthyosaurus, plesiosaurus, fish, ancient squid, phytoplankton (two of the major groups still in the ocean today first appeared), frogs, salamanders, crocodiles, turtles, snakes, pterosaurs (a group of flying reptiles), moss, ferns, spiders, scorpions, centipedes (thrived), grasshoppers (first appeared), etc. As I said, the list is very long.

4. Massive change and rejuvenation (appearance of Mammals)

Last but definitely not least characteristic of the Triassic is that it was the time of tremendous change and rejuvenation. Life that survived the so-called Great Dying repopulated the planet and gave rise to new creatures, such as rodent-size mammals and the first dinosaurs.

Perhaps the biggest changes came with the evolution of dinosaurs and the first mammals in the late Triassic, starting around 230 million years ago (Eozostrodon, Coelophysis, Plateosaurus)

The Triassic finished in the same way it began. Something, perhaps a volcanic belch or an asteroid collision caused another mass extinction. Dinosaurs, however, survived and went on to dominate the Jurassic. And the rest is history. :)

Which of the following is a divergent boundary?

skelet666 [1.2K]

Among the choices given, an example of the divergent boundary is letter C. Oceanic-continental. When we speak of divergent boundary, we also refer to the constructive or extensional boundary. This is a feature which is linear in nature and exist between two tectonic plates that tend to move away from each other.
