Blood dries over time. How quickly this happens depends on the surface on which the blood landed, how much blood the spatter contains, and the heat and humidity at the crime scene, but as a rule the outer edges of the stain dry first. Consequently, after the interior portion flakes off or is smeared by an object, a dry blood spatter can skeletonize, that is, leave behind a ring similar in appearance (if not color) to a water ring on a coffee table. Patterns of drying help analysts determine how long an assault went on, detect whether it took place all at once or in stages, and nail down possible crime scene contamination. Clotting patterns in blood provide similar information and can help nail down the time factor if analysts arrive at the scene before blood can dry. Clotting begins within 3 to 15 minutes, but actual times vary by amount, surface type and environment. Mixed levels of clotting can indicate that multiple blows or gunshots occurred over time
Answer:
Gas Sulfur Dioxide and Ash
Explanation:
Gas sulphur dioxide and ash have a cooling effect on the surrounding environment after a volcanic eruption. The gas sulphur dioxide has special properties which allows it to reflect sunlight away from Earth. It also reflects other volcanic gases in the atmosphere, which ensures cooling at the site of the volcano.

I think the correct answer from the choices listed above is option C. <span>In the statement above, Pb-206 is known as the daughter while U-238 is the parent. Hope this answers the question. Have a nice day. Feel free to ask more questions.</span>
The scale used to measure the intensity of ice storms is called the Sperry–Piltz Ice Accumulation Index, <span>based on the expected footprint of an ice storm, the expected ice accumulation as a result of a storm, and the expected damage a storm inflicts on human-built structures.
Meteorologists use Dual Polarization Radar, and the Q2 a mix of sensors and algorithms to predict precipitation.
Yes ice storms can be predicted by weather agencies, and it depends how fast it is detected and how severe it is.
