<span>the spiral arms of the milky way was made of: D. younger stars and gaseous nebulae
The spiral arms of the mily way was organized into four spiral arms, and since it was made of younger stars and gaseous nebulae, Spiral arms typically contain a higher density of interstellar gas and dust than the Galactic average as well as a greater concentration of star formation</span>
Answer:
- Plate movements on Earth’s crust create stress.
- This adds energy to the crust, which then bends and breaks, forming mountains and geological basins.
Explanation:
The tectonic plates literally float over the magma. Thus, what makes the tectonic plates move is precisely the movement of this magma! And this movement does not happen at all, but in a cyclical variation, which we call Earth convection currents or cells.
The movement of tectonic plates moving over the asthenosphere (pasty part) interacting over time in a geodynamic process that results in the origin of mountains and geological basins, causing seismic quakes (earthquakes and tidal wave), volcanism, magmatism and other geological events (formation of mountain ranges and underwater pits) all due to these plate movements.
The trolleys have been reduced over the last decades, after their initial increase as a public transportation, when new and better ways were discovered/produced for transport, their decline has started.
The buses since their invention, had grown in number and became a very important part of every city's public transportation, and still are.
The rapid transit is the most recent one of the mentioned in here. It's popularity has grown, number increased, and is very practical because it is not causing traffic mess. It is very important transport asset nowadays and makes lives of millions of people much easier.
