1. What type of heat transfer causes the movement of tectonics plates.
creativ13 [48]
1) heat from radioactive decay in the core of the Earth heard the mantle.
2) Plates move averagely only a few cm a year, this has been happening ever since the planet formed and cooled to give a thick crust so this movement has added up over many years to move plates far from where they started.
3) because the mantle is heated and is able to flow slowly, convection currents are set up which cause the plates on the crust to move.

  • Hadean eon.
  • Cenozoic eon
  • Mesozoic eon.
  • Proterozoic Eon
  • Paleozoic eon

Explanation:

  • The Proterozoic Eon continued for about 2,500 to 541 mn years ago and it preceded the Archean. Consisting of the deepwater deposits and the strata,  and showed a rapid continental acceleration and the occurrence of the first known glaciations also to place.
  • The paleozoic eon was for about 542 to 251mn years ago and it was divided into the six geological period ad they started after the breakup of the supercontinent as Pangea.
  • The archean eon is an eon that was for about4,000 to 2,500 mn years ago with a tectonic layer of rocks and rocks were more active than they are now. Formation of the mudstone and the volcanic sediments.
  • The Mesozoic era was about 252 to 66 mn years ago and it was the age of reptiles and the coniferous, as Mesozoic is the middle life and is one of the three eras of the Phanerozoic eon.
  • Cenozoic is a new life and is the most recent phase of the geologic eras. ad extends from about 66 mn yer ago. Known as the extinction event of the earth.
  • Hadean eon stared with the formation of the earth 4.6 billion years ago.

Describe what water regulation adaptations might have evolved in protists in hypertonic habitats such as great salt lake or in h
zhenek [66]

Answer:

The hypertonic habitats is home to saline protists which depend on salts for their survival.

Explanation:

  • Protists are a multicellular organism like the algae, don't from natural groups have invertebrates. They freely occupy the environment that contains liquid water.
  • As these microorganisms cant breath in freshwaters the need the salts to sustain themselves and responsible for the production of 30% of oxygen in the water sphere.
  • Diatoms and other oozes are some of the most beautiful protists found to date, they are also home to corals and stick to the body of seafloors. As for long, they have adapted to the same type of conditions.

If three seismic stations have the following P–S intervals: DUG = 57 sec, WUAZ = 73 sec, ISCO = 14 sec, what is the order from c
iragen [17]

Answer:

ISCO-DUG-WUAZ

Explanation:

Seismic waves of an earthquakes is recorded first in the station closest to the earthquake. The P wave is the faster moving wave and then the S wave. The faster the time it takes the P and S waves to register in the seismographer the closer the station to the site of the earthquake. Bearing this in mind, the wave was first registered in ISCO making it closest to the earthquake site, followed by DUG and then WAUZ.

ISCO (14sec)-DUG (57sec)-WUAZ (73sec)

Climate change is caused mainly by changes in the balance between the amount of solar radiation received by Earth and the amount
miss Akunina [59]

Answer:

Yes, that is very much true, just because climate change is caused mainly by changes in the balance between the amount of solar radiation received by Earth and the amount of heat radiated back into space by the Earth.

  • <u>Climate change:</u>

<em>"The change in stability of the environmental factors or the negative effects  in the equilibrium inside the environment is called as the climate change."</em>

  • <u>Global Warming And the green house effect:</u>

<em>"The overall rise in temperature of the earth spheres and its environment is termed as global warming, and its due the green house effect(the negative effect due to the increase level of CFC's)."</em>

  • <u>The trapped Sun radiation inside the earth's sphere:</u>

<em>"Due to large number of CFC's inside the earths sphere, as they results in trapping the radiation which needs to be radiated back out of the earth's sphere. Causing the rise in temperature of the overall environment."</em>

Explanation:

  • The chloro, floro and carbon elements which are also termed as the CFC's in general are created due increase level of industrial waste presence in the environment, leading to more solar radiation trapped inside the outer sphere of the earth's protective shield. Due, to this process the gasses are trapped inside the earth's sphere resulting in the rise in temperature.
  • <u>Consequences of Climate Change:</u>
  1. As our earth passed from various levels and situations and as there were also some ice ages, which almost resulted in creating inhabitable situations for the living beings.
  2. But, these days earth is facing some alarming situations in the form of high temperature in its environment, which is some how leading to some thing more worse.
  3. There will be less resources of food in the near future and most importantly there will be species like polar bears and some marine animals who will face extinction due to the rise in temperature inside the environment.
