This question will appear on exam 1 next week. try answering this and turn it in at the beginning of class on 7/11. be sure to use full sentences when describing. sketch, label, and describe the major layers of earth. include in your description the chemical composition and physical properties. be sure to include the difference between continental and oceanic crust. next, sketch and describe the difference between lithosphere and asthenosphere. (see lecture 2 slides 17-27) 1.

sediment layers stop spreading when they reach a barrier or they run out of sedimentary material. lateral spreading is the movement of gently to steeply sloping, saturated soil deposits caused by earthquake-induced liquefaction. i hope this . : )

it is very hard for the climatologists to precisely predict how will the global temperatures be changing so there's lots of models, some of which differ significantly, this is due to multiple factors, and probably the most important is the human activity.

humans have been a key factor in climate change around the globe since the start of the industrial revolution, and in the past few decades the consequences are becoming more obvious. there's lots of emission of pollutants in the atmosphere as well as changing the environment on the surface itself, so it's really hard to predict how will that go in the future because there's some countries that are reducing the damage and are going towards green energy, while others are stubbornly continuing with pollution and damages to the environment.
