energy
By the currents themselves - water contains oxygen (hence H2O), and nutrients, thanks to decaying (biotic) matter which, yes, contains nutrients even when no longer living.
Sediments eroded from mountainsides and transported in streams are an example of the conservation of mass. The total amount of sediment that is eroded from the mountainside remains constant as it is transported by streams to other locations.
In solids, matter is transported through atomic vibrations and lattice structure. In liquids, matter is transported through the movement of particles via convection and diffusion. In gases, matter is transported through random motion of particles due to differences in pressure and temperature.
almost everything besides stuff that u can't hold besides air for example: pencil, paper, pen, soccer ball: soccer's my favorite sport! actually even things that you can't touch are matter including air. things that you can't touch that aren't matter are things such as energy.
Matter
The tune of currents delivers you straight from past to present no matter where you are.
This process is best seen as an example of the conversion of mechanical energy into potential energy. The kinetic energy of the moving water impacts the rocks, breaking them down into smaller pieces. These pieces are then transported downstream where they accumulate as sediment, storing potential energy until they are deposited elsewhere.
Water itself is not energy, but it can contain and transfer energy. For example, water can hold thermal energy in the form of heat, kinetic energy in the form of waves or currents, and potential energy in the form of water stored in a reservoir.
An example of a state of matter besides ice is liquid water. Water is able to exist in three different states - solid (ice), liquid (water), and gas (water vapor) - depending on the temperature and pressure conditions.
No, that's Star Trek technology!
matter
Convection currents occur in liquid. Heat excites the matter near the source and causes it to rise, making nearby matter rush in to fill the space. Then that matter is heated, rises, and so on. A good example of this is the Earth's mantle: heat from the core is dispersed by convection currents.
