Glacial periods are caused by?
progressive cooling of earths surface. earths heat balance could change as orbit alters.solar radiation fluctuations, periodic changes in earth tilt and orbit. loss of heat from earths surface through reduction of carbon dioxide content of atmosphere. volcanic eruptions, short term cooling of globe could increase effect if lots erupted over longer periods of time. volcanoes and climate, the little ice age 1645-1715.
What sudden event could change the earths atmosphere?
The eruption of a very large volcano
In what field do scientists study the processes that change earths composition?
I think that it's geochemistry, but I could be wrong.
How many times is the suns radius bigger than earths surface?
109 Actually, no. 109 would probably be for Jupiter. For Earth, hundreds of Earth's surface could fit in the sun's radius.
How do intrusive igneous rocks become visible in the surface of earth?
it easly wears away and can travel by magma streams or rivers or could wear away into particles called protons and gets blown away by the wind.it can then land somewhere to slowly collect more particles to form an igneous rock in a random place
What could happen to earths surface if there was a change in the water cycle?
There could be change in the content of water. It will affect the level of water in the water bodies.
A reference point for determining position and motion could be?
The earths surface, a building, and a moving object
What wears down and builds up earths surface?
Weathering, erosion, and deposition. Earth's surface could also be built up by volcanism.
What planet temperature is closest to the earths?
Mercury has an average surface temperature (67°) closest to the Earths average surface temperature (14°C). The temperature on Mercury varies a lot though - you could argue that Mars is closer in temperature.

How do internal and external forces cause changes to Earths surface?
Most common change to the Earths surface from internal forces would most likely be earthquakes and volcano eruptions. External forces could be considered meteor strikes, or possibly the effects of gravity on the oceans ( Tides ) Global warming is also melting glaciers and causing a growth in arid regions. kapm
Whether you could see it or not how much of the Earths surface is always lit?
Ask dominick Bass he knows. Been
What sudden event could change the earths atmosphere?
The eruption of a very large volcano
What will be the effect on radiation received at earths surface of a decrease of ozone in the stratosphere?
Decrease of ozone in the stratosphere could cause UV to enter the surface. These could cause skin cancer and the immune system to weak.
How could a scientists use igneous rocks to study the materials found deep below earths surface?
because the igneous rock comes from below earth's surface
How does the earth-sun relationship affect physical processes and patterns on earths surface?
You could fit about 1.3 million earths in the moon
In what field do scientists study the processes that change earths composition?
I think that it's geochemistry, but I could be wrong.
