In what way are the chemical equations useful to us? ↵Chemical equation gives us the complete information about the reaction taking place. It tells the number of atoms of each element participating in the reaction. It tells the neccerssary requirements such as temprature, catalyst, etc. It also tells us the state of the elements in […]
What are three things that affect longshore currents?
What are three things that affect longshore currents? When a wave breaks at a more acute (steep) angle on a beach, encounters a steeper beach slope, or is very high, longshore currents increase in velocity. Conversely, a wider breaking angle, gentler beach slope, and lower wave height slows a longshore current’s velocity. What causes long […]
