True.

A region can affect its human inhabitants in many ways. If it’s arid it’s hard to farm, if theirs to much rain the crops and soil wash away, etc

Answer:

So the wavelength of light is 1015.7 nm

Explanation:

From Wein's displacement law, we can write the following formula;

$\lambda _{MAX}\times T=K$ here, $\lambda _{MAX}$ is the wavelength of maximum radiation in meters

T is the absolute temperature (in Kelvin) for maximum radiation

K is the constant has a value of $2.898\times 10^{-3}m-kelvin$

Given here, T = 2853 K

And we need to find $\lambda _{MAX}$

Putting the values in formula

$\lambda _{max}\times 2853=2.898\times 10^{-3}$

$\lambda _{max}=1.0157\times 10^{-6}m$

$\lambda _{max}=1015.7\times 10^{-9}m=1015.7nm$

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. :)

The apparent deflection of air masses to the right or left (depending on latitude) as they move from one latitude to another is

ehidna [41]

Answer:

Coriolis effect

Explanation:

The Coriolis effect is an apparent force, corresponding to the earth's surface, which makes deflection of any moving object (air masses) to the right in Northern Hemisphere and to the left in Southern Hemisphere because of the earth's rotation. The Coriolis effect is a primary cause of various large scale weather patterns e.g. Coriolis effect is responsible for cyclones and trade winds.

The weather effecting fast moving objects e.g planes, missiles,rockets is affected by the Coriolis effect. Coriolis effect determines the direction of winds. A plane that flies along a path (north-south) should not fly directly towards the target location but it should fly either a little right or left of it to get to the target location.

The Coriolis effect also have an impact on ocean patterns. The winds power the seas. There are very similar patterns of ocean and atmospheric circulation. The effect is that ocean flows in their basins in the Northern Hemisphere and counter clockwise in the Southern Hemisphere.
