1: The crust includes both the dry land and the ocean floor. It is thinnest beneath the ocean and thickest under high mountains. The crust ranges from 5 to 40 kilometers thick. The crust beneath the ocean is called oceanic crust.
2: Drylands are areas which face great water scarcity. ... They are highly adapted to climatic variability and water stress, but also extremely vulnerable to damaging human activities such as deforestation, overgrazing and unsustainable agricultural practices, which cause land degradation.
3: The seabed (also known as the seafloor, sea floor, or ocean floor) is the bottom of the ocean, no matter how deep. All floors of the ocean are known as 'seabeds'.
4: 660 kilometers
5: The mantle is composed of very hot, dense rock. This layer of rock even flows like asphalt under a heavy weight. ... The movement of the mantle is the reason that the plates of the Earth move! The temperature of the mantle varies from 1600 degrees Fahrenheit at the top to about 4000 degrees Fahrenheit near the bottom.
6: The mantle is divided into the upper mantle and lower mantle. Additionally, the upper mantle is divided into 2 parts: a thin portion of the lithosphere and the asthenosphere.
7: tectonic plates
8: Inner Core
9: NiFe
Sorry, I only know up to 9...number 10 is kind of confusing since I don't know what their talking about because I at least need a name for what I'm measuring. But I hope 1 - 9 helps.. ^^
