The bar scale is the ruler-like graphic scale and on this picture, it is located in the bottom left corner. The way you measure with it is you take a ruler or a compass and measure the distance between the two points. Then you use the distances on the bar scale and the distance you measured to see the air distance between the two points.
The answer is - 30.
In the last 800,000 years, in a span of 1,000 years it never happened that the CO2 go upwards or downwards for more than 30 ppm. It has always been a slow process in this period and as much as the jumps were big, that never surpassed this number. On the other hand we are witnessing that this has happened nowadays in just 13 years, and that is very concerning because such rapid changes of CO2 in the atmosphere brings rapid changes in the climate and it will be a global catastrophe if this trend continues.
Oceanography but the study of ocean creatures is Marine Biology
ANSWER: False
EXPLANATION: Glaciers move downhill due to gravity and internal deformation. Until the thickness exceeds 50 meters, it causes plastic move which causes them to start them to move. They also move through basal sliding in which it slides over terrain, lubricated by the presence of liquid water created from ice that melts under high pressure from frictional heating.
