Why does the Inter tropical Convergence Zone shift?
Earth scienceAsked by: Vanessa Martel The shifting of ITCZ is the result of the Earth’s rotation, axis inclination and the translation of Earth around the Sun. Seasons are the result of this. ITCZ moves toward the hemisphere with most heat, wich are either hemisphere summers. Why are the tropics shifting? Earth’s tropics are expanding poleward and
Has there ever been a case where we have found what appears to be a prehistoric fossil but have no way of dating it?
Earth scienceAsked by: Vanessa Martel What is fossil dating? To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to
Is this a fossil or a mark on the stone
Earth scienceAsked by: Danielle Dunn How do you tell if a stone is a fossil? It is also a good idea to look for signs that the rock contains a fossil before trying to break it, part of a fossil may be visible on the surface of the rock. You can identify the limestone by it’s

Is Table Rock Beach still closed? Conversation. All city beaches in Laguna Beach are closed. This includes beaches operated by the County
What is the difference between waterlogging and flooding?
Earth scienceAsked by: Richard Reyes WATERLOGGING : Waterlogging refers to the saturation of soil with water. Soil may be regarded as waterlogged when it is nearly saturated with water much of the time such that its air phase is restricted and anaerobic conditions prevail. FLOOD : Flooding is a temporary overflow of water onto land that
How do I represent wind direction on a UTM (Universal Transverse Mercator) map projection?
Earth scienceAsked by: Stacy Wilson How do you read a Universal Transverse Mercator? The UTM (Universal Transverse Mercator) coordinate system divides the world into sixty north-south zones, each 6 degrees of longitude wide. UTM zones are numbered consecutively beginning with Zone 1, which includes the westernmost point of Alaska, and progress eastward to Zone 19, which
What is the origin of oil?
Earth scienceAsked by: Stacy Wilson Petroleum, also called crude oil, is a fossil fuel. Like coal and natural gas, petroleum was formed from the remains of ancient marine organisms, such as plants, algae, and bacteria. What is oil short answer? Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture
What are the natural causes for methane formation?
Earth scienceAsked by: Emma Jones Methane is produced by the breakdown or decay of organic material and can be introduced into the atmosphere by either natural processes – such as the decay of plant material in wetlands, the seepage of gas from underground deposits or the digestion of food by cattle – or human activities –
Could we plant enough trees to offset greenhouse gas emissions?
Earth scienceAsked by: Emma Jones How many trees would it take to offset global warming? A single mature tree, meanwhile, may take in about 50 pounds of carbon dioxide per year. At this rate, it would take 640 trees per person to account for all American emissions, which adds up to more than 200 billion trees.
Is there a correlation between the underwater geological activity and topology of the mid Atlantic ridge/ South American plate and the Gulf Stream?
Earth scienceAsked by: Lina Smith What is the Mid-Atlantic Ridge and how does it play a role in plate tectonics? In between these continents lies the Mid-Atlantic Ridge, a site where new plates are formed and a dividing line between plates moving to the west and those moving to the east; beneath this ridge, material rises
