All questions are multiple choice. I ONLY NEED the correct answers. I DO NOT need an explanation. Thank you!
Question 1:
Refer to the model below. The curved arrow represents which of the following processes? Infrared radiation being reradiated back to O Earth's surface by gases in the atmosphere. 0 Infrared radiation entering Earth's atmosphere. 0 UV radiation entering Earth's atmosphere. UV radiation being reradiated back to O Earth's surface by gases in the atmosphere. Which of the following is NOT considered when measuring an individual's ecological footprint? the type of car the individual chooses to O drive 0 the location where an individual lives O the food that an individual eats 0 how much energy the individual's home uses up CURRENT 380 340 HIGHEST HISTORICAL CO, LEVEL 1950 300 CO, (parts per million) 260 220 180 800 700 600 500 400 300 200 100 0 Thousands of years before today (0 = 1950) Based on the graph above, how many thousands of years before today was C02 300 parts per million? https://climate.nasa.gov/vital-signs/carbon-dioxide/ O approximately 700 thousands years before today. O approximately 500 million years before today. O approximately 300 million years before today. O approximately 100 million years before today.CURRENT 380 340 HIGHEST HISTORICAL CO, LEVEL 1950 300 CO, (parts per million) 260 220 180 800 700 600 500 400 300 200 100 0 Thousands of years before today (0 = 1950) What is the current level of CO2 in parts per million? https://climate.nasa.gov/vital-signs/carbon-dioxide/ O Approximately 300 parts per million. O Approximately 320 parts per million. O Approximately 360 parts per million.

What could be a plausible explanation for the occasional small dips in the 002 levels? There was no 002 released in the 0 atmosphere during that time so the levels dropped. O The seasons changed causing a change in the 002 levels in the atmosphere. 0 The dips are not large enough to have any scientific significance. The positive trend means that there is no 0 . change In CO2. million square km 1934 1992 EDGE EDDB 2015 YEAR Summ- dunk has: on Based on the graph above, what can you infer about sea ice levels? Sea ice levels are remaining steady over the last 30 years. Sea ice levels are rising over the last 30 years. Sea ice levels are declining over the last 30 years. You cannot discern sea ice levels from this graph.

Q As 002 levels rise, sea ice levels rise. 0 As 002 levels fall, sea ice levels fall. Which of the following best describes the current rise in atmospheric CO2? O More volcanic eruptions occurring. O More burning of fossil fuels for human use. O Sea levels rising. O Destruction of biodiversity
