What are the principal divisions of the solid earth based on compositional differences?
The principal divisions of the solid Earth based on compositional differences are the crust, mantle, and core. The crust is the outermost layer and is composed mainly of lighter elements like silicon and oxygen. The mantle lies beneath the crust and consists of denser silicate minerals. The Earth's core is located at the center and is primarily made up of iron and nickel.
What are 3 things that affect surface ocean currents?
Wind patterns, Earth's rotation (Coriolis effect), and the shape of the ocean basins are three factors that affect surface ocean currents.
What are the three areas of the earth?
The three main areas of the Earth are the core, mantle, and crust. The core is divided into the inner and outer core, composed of nickel and iron. The mantle is a semi-solid layer located between the core and crust, while the crust is the Earth's outermost layer where we live.
What is the fundamental difference between surveying and leveling?
Surveying involves measuring and mapping the three-dimensional positions of points on the Earth's surface, while leveling focuses on determining and establishing the elevation differences between points. Surveying is more comprehensive and involves determining both horizontal and vertical positions, whereas leveling is primarily concerned with vertical positioning along a level line or plane.
