The freshwater sources that are generally in continuous motion and follow a defined path are called streams and rivers.
If I were to improve the lab then I will make the following changes:
The experiment aimed to observe and model the effects of rivers on erosion. So, I can make a virtual model of the river and can compare the velocity, gradients and volume of rivers.
Comparison between the low and high factors listed can help in computing the effect of the powerful river on erosion.
The high velocity. gradient and volume of the river will cause more erosion as it exerts more force.
The low volume, gradient and velocity river will affect in a less manner on erosion.
Due to electron deficiency in a metal cation, they cannot form a covalent bond beacuse it means to share electrons. By contrast metal cation seek for electrons. In an ionic bond, one atom give electrons, while another atom recevie electron. Because of that, this is the better option to metal cations.
