Aniket Bharati, Date – 2/16/2024 You will need to use the web application shown in the video tutorial in Lab 4. For this activity, you will be estimating the age of the Hadriaca Patera region (image 1 in the web app).  Count the number of impact craters greater than 500 m in diameter for the square region of 15.42 km by 15.42 km. Number of Craters: 5  Non-impact craters for that square region should not be counted.  Once you know the number of impact craters for that square region use the following formula to estimate number of craters for 1 mln sq. km: o # of craters/ 1 mlnsq. km = 1,000,000 * (# of craters) / (linear size of region) 2 - 10 / 1millsq km = 1,000,000*(10) / (15.42 km) 2 - # of craters/ 1 mlnsq. km = 1,000,000 * (10) / (237.7764 km) 2 - # of craters/ 1 mlnsq. km = 42,056.319 km 2 Structure Hadriaca Patera is Approximately: 3 X 10 9 or 3 billion years Old.
