(a) The mantle is the largest layer by volume of the earth.
(b) The mantle is solid except for a partially melted region in its upper part called asthenosphere.
(c) The upper mantle above the asthenosphere is considered part of the lithosphere.
(d) Large scale convection currents occur in the mantle.
(e) The mantle is dominated by aluminum rich minerals. ]]> 2017-09-19 14:40:14 UTC https://padlet.com/user_1412471615/a22kwullum6t/wish/188920216 * Post a diagram of rock cycle user_1412471615 https://padlet.com/user_1412471615/a22kwullum6t/wish/188920889 2017-09-19 14:41:26 UTC https://padlet.com/user_1412471615/a22kwullum6t/wish/188920889 What are the components of soil? user_1412471615 https://padlet.com/user_1412471615/a22kwullum6t/wish/188921202 water, eroded inorganic parent material, air, and organic matter

Usually found in forest soils
A horizon: Small mineral particles mixed with the broken down organic material from O horizon
E horizon: Very few nutrients found
B horizon: Subsoil, less organic material than horizon A
C horizon: Weathered parent material
R horizon: Bedrock]]> 2017-09-21 14:14:30 UTC https://padlet.com/user_1412471615/a22kwullum6t/wish/189759891 https://padlet.com/user_1412471615/a22kwullum6t/wish/189760298 The very top layer, O, is the grass. The next layer, A, is called the topsoil. Beneath that is E, which is called transition. The next layer, B, is called the subsoil. From layers O and E is called the zone of leaching. from E to B is called the zone of accumulation. Next is layer C containing weathered parent material. Below all of that is a layer of bedrock.]]> 2017-09-21 14:15:11 UTC https://padlet.com/user_1412471615/a22kwullum6t/wish/189760298 Coriolis effect user_1412471615 https://padlet.com/user_1412471615/a22kwullum6t/wish/189803945 2017-09-21 15:32:11 UTC https://padlet.com/user_1412471615/a22kwullum6t/wish/189803945 https://padlet.com/user_1412471615/a22kwullum6t/wish/189806259 2017-09-21 15:36:17 UTC https://padlet.com/user_1412471615/a22kwullum6t/wish/189806259 https://padlet.com/user_1412471615/a22kwullum6t/wish/189807048 2017-09-21 15:37:43 UTC https://padlet.com/user_1412471615/a22kwullum6t/wish/189807048
