What is the purpose of a geological time scale?
The reason Geologic Timescales are used are to give sense of what time begining from 4.5 billion years ago, and the satges through Evolution. That's how it's possibly percieved, I am not accuratly certain, so do research and come up with a possible answer to counter my statement.
What year did glaciers start to form?
Volcanoes have been around since the formation of earth they are vents to relieve pressure from the earth's core.
What does it tell us about the earth?
The Earth is the third planet from the sun in our solar system, the only known planet to support life, and has a diverse range of ecosystems. It contains a mix of land, water, and atmosphere that sustains a delicate balance for life to thrive.
What proof do geologists have that the earth has changed over time?
Months, years or even centuries aren't helpful for thinking about earth's long history. Because the time span of earth's past is so great,geologist use the geologic time scale to show earths history. :they didn't discover much, but they use fossils,DNA,and reacher many things.:
What are banded iron formations and what do they tell us about the evolution of Earth's atmosphere over geologic time?
Banded iron formations are sedimentary rocks consisting of alternating layers of iron-rich minerals and chert. They indicate periods of high oxygen levels in Earth's past, as the iron in these formations could only have been deposited in an oxygenated environment. The presence of banded iron formations suggests that significant amounts of atmospheric oxygen were produced by photosynthetic organisms, leading to the oxidation of iron in seawater.
How does radioactivity formation tell Earth's geologic story?
It Does a man
What does this information tell you about the geologic history of those areas?
Plant life could be used to interpret the geologic history of a location.
What can the Richter scale tell us when it is used to compare earthquackes?
A richter's scale shows the intensity of an earth quake on a scale from 0-10. The greater the number, the more the intensity of the earth quake which leads to more destruction of life and property
What do lava samples tell scientists about what has happened to the earth magnetic field over geologic time?
The magnetic field periodically changes its orientation.
What part of a map tell the relationship of distance shown on a real distance on earth?
The scale bar.
What do scientists use to mark boundaries in the geologic time scale?
I'm thinking it's index fossils because index fossils tell when or how old the layer it was found in. If that's what your asking.
How can people tell if the world is going to end?
well if the scale for a earthquake will happen and if 2012 is the world will die is about 1000000000000.6 on the scale which will make the earth only have water
What does a food web tell us about life?
it tells us that without an habitat there would be no life on earth

What the rocks of the sierra nevadas tell geologist about the geologic history of California?
Granite
How do scientists put fossils in order on the geologic time scale?
Location. Different layers of rock/soil tell a roughly chronological tale of the past, barring cataclysm. There are enough undisturbed sites worldwide that a mosaic can be discerned. Good question.
What is used to convert the distance on the map and the actual distance in real life?
Somewhere on a map there will be a scale. The scale will tell you the ratio of a distance on the map to the corresponding distance on the ground. eg 1cm = 10km
