Earth is comprised of four systems, or spheres. which of these spheres do each of the five branches of earth science study?

Answer;

-Geologists study the lithosphere.

-Oceanographers study the hydrosphere.

-Meteorologists study the atmosphere.

-Astronomers focus beyond the Earth System and study the systems of other planets and heavenly bodies.

-And environmental scientists might study the atmosphere, biosphere, or hydrosphere.

Explanation;

-Earth science is the science that focuses on planet Earth and its place in the universe. The study of volcanic eruptions is one field in earth science.

-A system is a portion of the universe and all of its components, processes, and interactions. Our solar system contains eight planets and one dwarf planet which orbit a single sun.

-Earth is made up of four spheres: the lithosphere, hydrosphere, atmosphere, and biosphere. Changes in any part of the Earth's system affects all other spheres. For example, storms form in the atmosphere which bring rain. The rain affects the hydrosphere by increasing the amount of water in a river, which affect the flow of the river. Flowing rivers change the surface of the lithosphere. Plants and animals in the biosphere depend on water to survive.

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
