Answer:
Two plates pull towards each other
Explanation:
Along a convergent plate boundary, two plates moves towards each other as the move in the same direction.
This results in different forms of plate interactions depending on the plate types.
- At an ocean - ocean and continental - ocean convergent front, subduction of the oceanic plate occurs. This is because the oceanic plate below is denser than the asthenosphere.
- At a continental - continental convergent front, the continental crust is pulls upward and build up as a mountain.
- The subduction produces trenches and some volcanic islands.
In a 0.01 M solution of HCl, Litmus will be red. Litmus paper will turn into red in acidic conditions. Hydrochloric acid is an acid. Litmus is an indicator for acidity and alkalinity made from inchens.
Sound travels in waves and the height of the wave is the loudness of the sound.
To decrease sound, you need to make the waves not so high, so you can
- decrease the amplitude
- decrease the height of the crest (lower the top of the wave down)
- increase the height of the trough (bring the bottom of the wave up)
It's all about getting the wave to be closer to the center, to not be so high and low, but to be flatter.
