Jigsaw Research Formative Check

In the "Changes to Glaciers" article from Jigsaw reading; which answer BEST summarizes the scientist's claim?

• Warmer Temperatures cause glaciers and ice sheets to lose more water to melting than is added from new snow

• Warmer Temperatures cause glaciers and ice sheets to gain more water feom new snow than is lost from melting

• Colder Temperatures cause glaciers and ice sheets to lose more water to melting than is added from new snow

• There has been no change in glaciers and ice sheets over the past 200+ years

Explain what this graph is telling us about Glaciers

• The average mass of glaciers has increased from 1950-2020

• the average mass of glaciers has decreased from 1950-2020

• there has been no change in the mass of glaciers from 1950-2020

• glaciers are moving farther south due to ice worms

What does this graph tell us from the Glaciers article?

• It tells us that the number of glaciers tested has increased over the years

• it tells us that the numbers of glaciers tested has decreased over the years

• it tells us that the number of glaciers tested has not changed in over 70 years

In the "Changes to Groundwater" Article; Please select the answer that BEST summarizes the claim made by the scientist

• Changes in air temperature do not directly affect groundwater. Warmer air temperatures can cause less precipitation so that groundwater does not refill as quickly as it’s pumped

• Changes in air temperature directly affect groundwater. Colder air temperatures can cause more precipitation so that groundwater refills more quickly than it is pumped

• Groundwater is entirely dependent on snow melting

• Groundwater is an infinte source of water; we will never run out of it

Which answer best describes what this data chart is telling us?

• It is telling about how much water is stored underground in different areas of the United States

• It is telling about how much water is stored above ground in different areas of the United States

• It is telling about how much water in the United States is available because of glaciers melting

• It tells us about how much rainfall we can expect in different areas of the United States each year

Based on this data chart; is the amount of groundwater in Nebraska increasing, decreasing, or staying the same?

• Increasing

• Decreasing

• Staying The Same

In the "Changes to StreamFlow" Article; which option BEST describes the claim made by scientists

• Warmer temperatures can cause snow to melt faster and earlier in the year. Warmer temperatures cause some places to get more precipitation and other places to get less precipitation

• Warmer temperatures can cause snow to melt slower and later in the year. Warmer temperatures cause no change in precipitation

• Warmer temperatures have no effect on snow melt and no effect on precipitation

• Streams only exist because of snow melt; they do not rely on rainfall at all

What do the Big, Blue Triangles mean on this Data Chart?

• It means that streamflow has decreased by 20%

• It means that streamflow has not changed

• It means that streamflow has increased by at least 50%

• It means that streamflow has increased by 20%

Based on this data table; is Nebraska experiencing any change in Winter to Spring runoff in their streams?

• Yes, they are experiencing run off 10 days earlier

• Yes they are experiencing runoff 10 days later

• No, there is no evidence of any change in Nebraska's runoff

According to the "Glaciers and Water Supply" Article; What percentage of freshwater on Earth is found in Glaciers?

• 25%

• 50%

• none, glaciers are made of salt water

• 70%
