The separation of Australia and Antarctica,The separation of Greenland and North America,The continued growth of the Atlantic Ocean are during the cenozoic era of the phanerozoic eon .
The Paleozoic, Mesozoic, and Cenozoic eras make up the three primary time periods that make up the Phanerozoic, the aeon of observable life, which are separated mostly by distinctive assemblages of life-forms. The kind of fossil that were discovered influenced the names of these. The word Cenozoic, which means "new life," refers to the most recent age. This is so because the fossils resemble modern-day animals and flora.
The Cenozoic Era covers the period from the extinction of the dinosaurs and to the present day. Mammals stepped in to fill the void left behind by the dinosaur extinction because mass extinctions provide conditions for new life to flourish. They developed into several species that we now identify, including humans! Cenozoic Era, the third of Earth's main eras, began around 66 million years ago.

A bio geophysical feedback mechanism in the Sahel relates: reduced vegetation to a decrease in surface temperatures and a reduction in rainfall.
What is rainfall?When water vapor in the atmosphere condenses into droplets, they descend to the ground due to gravity. The majority of the fresh water on Earth is deposited by rain, which is an important part of the water cycle.
It offers water for hydroelectric power plants, irrigation for crops, and favorable environmental conditions for a variety of ecosystems.
The movement of moisture along three-dimensional areas of temperature and moisture differences known as weather fronts is the primary factor in the formation of rain.
Convective clouds like cumulonimbus, which are able to coalesce into slender rainbands when there is adequate moisture and upward motion, can produce precipitation if those conditions are met.
When upslope flow is maximum inside windward sides of the terrain at elevation, which encourages moist air to concentrate, severe precipitation is possible in mountainous places.

How do chlorofluorocarbons affect earth's ozone layer?
Answer:
Chlorofluorocarbons (CFCs) are chemicals that release chlorine and bromine into the atmosphere, which break down the ozone molecules in the ozone layer and cause depletion of the ozone layer.
Chlorofluorocarbons result in the depletion of the ozone layer of the earth.
The Earth's ozone layer shields all life from the sun's damaging radiation, but human actions have harmed it. Less ozone-layer protection from ultraviolet (UV) radiation will eventually harm crops and lead to greater instances of skin cancer and cataracts.
The ozone layer in the stratosphere absorbs some of the sun's radiation, preventing it from reaching the planet's surface. Most notably, it absorbs UVB light. UVB has been associated to a variety of negative outcomes, including skin cancer, cataracts, and crop and marine life damage.
When gaseous CFCs slowly climb into the stratosphere, they are broken down by intense UV light, releasing chlorine atoms, which subsequently combine with ozone molecules.

How do plates move at convergent plate boundaries?
Convergent (Colliding): This occurs when plates move towards each other and collide. When a continental plate meets an oceanic plate, the thinner, denser, and more flexible oceanic plate sinks beneath the thicker, more rigid continental plate. This is called subduction.
The plates in convergent boundaries come together and collide with each other and dense and thick plates sink under the less dense plate.
Convergent boundaries are where two lithospheric plates(plates over the land) move together or collide and the more dense plate sinks under the less dense plate.
A convergent plate boundary is a place where two tectonic plates are moving toward each other by some action, causing one plate to slide beneath the other. This process is also called subduction. The collision of these plates can result in earthquakes, volcanoes, the formation of mountains, and other geological events.
Earth's surface is formed up of two types of lithospheric plates i.e one is continental and the other is oceanic. The crust that makes up continental plates is thicker yet less dense than the oceanic crust because of the lighter rocks and minerals that compose it. Oceanic plates are made up of heavier basalt, the result of magma flows from mid-ocean ridges.
When plates converge, they result in three types of movements and they are oceanic plates collide with each other forming oceanic-oceanic boundaries, oceanic plates collide with continental plates forming oceanic-continental boundaries, or continental plates collide with each other forming continental-continental boundaries.

according to a new study released this week, which part of earth may have stopped turning?
The rotation of the Earth's inner core may have ceased, which could have caused it to go into reverse. Along with the mantle and semi-solid mantle, the Earth is made up of the inner, outer, and crustal layers.
Has the inner core of the Earth ceased to rotate?The inner core may be suffering a turning-back, according to their study. "We demonstrate surprise observations that imply the inner core has practically ceased its rotation in the previous decade," they stated.
Why did the Earth's rotation suddenly stop?The majority of our globe would become extremely hostile if it abruptly stopped rotating. The Earth rotates at almost 1700 km/h, and if our globe suddenly stopped, anything that isn't firmly connected to the bedrock would be moved. This is a result of motion's inertia, as previously mentioned.
