What is an example of dissolved oxygen?
What is an example of dissolved oxygen? Oxygen is added to water by: Re-aeration: Oxygen from air is dissolved in water at its surface, mostly through turbulence. Examples of this include: Water tumbling over rocks (rapids, waterfalls, riffles) Wave action Photosynthesis (during daylight) Plants produce oxygen when they photosynthesize. What level of dissolved oxygen is […]
Which has higher porosity clay or sand?
Which has higher porosity clay or sand? Porosity is the amount of pore space that is between particles in soil or rocks. Surprisingly, clay can have high porosity too because clay has a greater surface area than sand, therefore, more water can remain in the soil. What are two factors that determine the porosity of […]
