The correct option is a. There is very little rock record for earth’s first 600 million years because the surface of the Earth then was one huge ocean brain filled with hot water and nothing else.
The rock record is frequently referred to by geologists and other earth scientists. The only item other than the rocks that are present now is the rock record. The geologic events are not neatly organized in the rock record. Rock formations are eroded, buried, destroyed, split in half, melted, pressed together, and even turned on their side. Only "leftovers" that have not yet been recycled are "recorded" as elements of Earth's history. That is, the original rocks are frequently altered or destroyed when a region changes owing to a geologic process, making it challenging to investigate the circumstances that gave rise to the rock. However, everything we know about the Earth's past comes from examining the rock that was created by geologic processes.
Identify the FALSE statement. There is very little rock record for Earth's first 600 million years because
a. the surface then was one huge ocean basin filled with hot water and nothing else.
b. rocks of that age sank back down into the Earth.
c. intense meteorite bombardment may have destroyed most land surface.

Rain carries soil into a nearby pond. This is an interaction between which two "spheres" of the earth?.
Rain carrying soil into a nearby pond can be explained by the interplay of the geosphere and hydrosphere.
The hydrosphere interacts with the geosphere when bodies of water or rain cause land formations to erode. Rocks are broken down into small fragments and new rock patterns are created by rivers and rainstorms. The hydrosphere discharges snow and ice, which harden and cool the geosphere.
Precipitation, such as rain or snow, can fall to the surface of the Earth when a portion of air in the atmosphere becomes saturated with water. That precipitation facilitates weathering and erosion, two surface processes that gradually reduce huge rocks to smaller ones, thus bridging the hydrosphere and the geosphere.

Sally is most likely to work in the energy transmission pathways because she is fixing powerlines that were damaged during a storm.
What is Energy Transmission?
Transmission of energy is used to deal with the temporal mismatch between the production of (renewable) energy and changes in demand, in addition to transferring energy from the primary sites of generation to those sites. In an electric power system, transmission lines move electric energy from one location to another. They can transport direct current, alternating current, or a system that combines both. Also, overhead or subsurface wires can both carry electric current.
So, Sally is working in the career pathway of energy transmission as she is trying to fix the temporal mismatch between the production of energy and her powerline (i.e., demand).
