Heat from moving the Earths crust.

Heat such as the sun and volcanos.

Some of the causes for major changes during the geological history of earth is the heat and sun because they melted the ground and the snow when we had it.

Ian L said...

Some cases or reasons why there were major changes was because some of it had to do with volcanoes. Which the volcanoes made volcanic islands which was a major change.

heat, sun, photosynthesis.

Some of the major Events is the creation of oxygen from the meteorites that have fallen from space and some Bacteria has started to live

The moving of continents, the shifting of tectonic plates, and global warming/climate change are some causes for the major changes during the geological history of Earth.

Some of the Major Changes during the Geological History of Earth were that Meteorites hit very often on Earth's surface and the Meteorites contained Rare minerals and the first organisms on Earth.

The temperature from the sun balancing act, Changes in the reflectivity of earths atmosphere and surface, and The Greenhouse Effect causes the atmosphere to retain heat.

The sun's radiation was shielded from the Earth's surface, and then plant life exploded, and the first reptiles to walk on land.

The sun/heat causes some of these things.

The ice age, heat and sun, meteorites, the atmosphere,the creation of the ozone layer, and plants and animals.

The sun's radation, the moons pull. Radiation from the sun was blocked by a chemical called O-Zone. The life and plant life began in ocean's as well as normal life. Millions of years later plant life begins on land and the first reptiles walk onto the shore.

Very small changes in the Earth's orbit result in only a 4 degree Celsius in the global mean temperature which can have very dramatic impacts on the Earth system.

On major change is temperature and biological change

The ice age is one of the reasons why earth why the Earth is different! The Ice age ripped up rocks and dropped them all across the earth!

Nikki Newcomb said...

The volcanic eruptions causes some of these things.

The temperature us a lot to life because their is a certain temp that you could live from or die

The sun and or heat can cause some of these things.

A major change of the history of earth was the added oxygen to the atmosphere.
When major ice ages happened when the ice melted it released a lot of oxygen which caused the earth to have 99% oxygen and 1% of other stuff. Which is why we can breathe.

Meteor Impacts, heat, volcanic eruptions, and the effect that the moon has on the tides.

The absorbing of CO2 into rocks caused the sun's heat to not be trapped within the planet at all, in turn causing an ice age that lasted millions of years, which also killed almost all life on Earth.
