Fossils
These are the continents on which fossils have been discovered.
What are all of them.
Conditions of the atmosphere at a particular place and time (such as temperature and precipitation) are called this.
What is weather.
This is a flowing mass of ice and snow that forms on mountaintops and near the north and south poles.
What is a glacier.
These are the remains of ancient animals and plants.
What are fossils.
This is the main force that causes glaciers to move.
What is gravity.
This represents all the fossils that have ever been found.
What is the fossil record.
This is a global climate marked by long-term cold temperatures that cause glacial formation and expansion.
What is an ice age.
This is what it's called when a glacier is growing.
What is expansion.
This is the number of years over which fossils form.
What are millions (or billions).
This is what it's called when a glacier is shrinking.
What is retreating.
This is the type of rock in which fossils are most commonly found.
What is sedimentary rock.
These are some things that scientists study to learn about past changes to Earth's climate and environments. Name at least 2.
What are ice cores, fossils, and the fossil record.
This is what happens when the amount of snowfall exceeds the amount of snowmelt over many years.
What is how a glacier is formed.
This is the one of the first steps taken to try and determine the age of a fossil.
What is measure the age of the rock in which the fossil is found.
This is the sediment that is eroded and deposited as glaciers retreat and expand.
What is glacial till.
This is what turns once living organisms into fossils.
What are heat and pressure.
This is where Earth receives the most direct sunlight.
What is the equator.
This is what glaciers do to the land underneath them as they move.
What is weather and erode.
This is the name for wood that has turned into stone.
What is petrified wood.
This is the most likely explanation why the Jakobshavn Glacier set a world record for most distance traveled in one day.
What is energy from the sun caused it to melt and retreat.
This is the best explanation for how fossils of the same dinosaur have been found on different continents.
What is plate tectonics or connected continents.
These are the elements of ice cores that tell us about differences in the environment over time.
What are layers and bands.
This is the system in which glaciers participate when their water melts and changes from one form to another.
What is the water cycle.
This is most likely the case if we find a fish fossil in the desert.
What is the area used to be under water.
This is the most likely reason for why glaciers have been melting at a faster pace over the past hundred years.
What is the Earth's climate got warmer.
