Earth Science

a) A planet of radius R has a core of radius R/2 which has a uniform density ρc. The mantle also has a uniform density ρm and the two densities are related by ρc = yρm Determine y if C/MR^2 = 1/3.b) Assume the average density of the entire Earth ρE = 5515 kg/m3. Using the result you found for y, derive the average densities of the core and mantle, ρc and ρm, respectively. For comparison, the volume-averaged densities on Earth are ρm = 4480 kg/m3 and ρc = 10640 kg/m3 . Comment on what the main reason is for why the approximate values are different from the observed average densities. ...

Fronts And Cyclones

Part I Types of FrontsA front is defined as the boundary between two airmasses. The major types being:mT - maritime Tropical (moist and warm)mP - maritime Polar (moist and cold)cT - continental Tropical (dry and warm)cP - continental Polar (dry and cold)When any of these airmasses meet, they form a front. Depending on which airmasses meet and which airmass is moving forward (and which is moving out of the way) you will have different kinds of fronts.The two main types of fronts are cold fronts, where cold air is advancing forward toward warm air, and warm fronts, where warm air is advancing forward toward cold air. This video gives a brief overview of these two types of fronts:What are weather fronts? (Links to an external site.)What are weather fronts?Question 1: Describe three (3) differences between cold and warm fronts.There are other types of fronts, however. When a cold or warm front stalls, or stops moving, we call this a stationary...

Pacific NW

Lab Purpose and learning objectivesReport, describe, and interpret your observations of several features found in the Pacific NW.Formulate a hypothesis explaining how several landform features relate to each other and explain what took place to create them (Your story).Use the scientific method to structure your exploration and explanations.Instructions and Overviewa. You are going to investigate and solve a mystery about a geological phenomenon in our “backyard”. You will be given several pieces of evidence and multiple clues and hints containing geologic information for you to observe, formulate hypotheses about, and interpret. b. Using the eight pieces of evidence provided, and the large map of the Northwest with their locations, make observations and interpretations and record these in the table provided You will type these up and upload these to Canvas.c. Hints are provided along with the evidence to help guide your group and should be used for discussion when making your observations and interpretations. You do not need answer these...
