How Does the Moon Affect Our Ocean?

You see, the moon's gravity actually affects the entire Earth, not just the water, but because water is much less dense than land, we actually see the tides change. On the opposite side of the Earth— farthest from the moon where the moon's gravity is the weakest—we experience high tide because the rest of the Earth is being pulled away ...

Fluorspar: the EV critical mineral no one has heard of

Fluorspar in electric batteries. The main reason fluorspar is listed as a critical mineral in the US, EU, Australia and others, is the projected demand for electric vehicles (EVs), as well as to process silicon essential for solar panels. Fluorspar is used in all three main parts of an electric battery: cathode, electrolyte, anode.

Soil Pulling Away from Plant Pot: Causes and Solutions

What Causes Soil to Pull Away from the Sides of a Plant Pot. The main issue I had with the container planter I put together was that my soil kept pulling away from the sides of the container as it got drier. ... Bottom watering keeps the soil moist consistently, enabling the plant to get enough water. That way, you can prevent the plant from ...

Lead Barite Fluorspar Separation Method

How Water Moves Through Plants

The chief water movement in plants is through osmosis from the roots to the stems to the leaves. How does water transportation in plants occur? Water movement in plants occurs because plants have a special system to draw water in, conduct it through the body of the plant and eventually to release it to the surrounding environment.

Cohesive and adhesive forces are important for the transport of water from the roots to the leaves in plants. These forces create a "pull" on the water column. This pull results from the tendency of water molecules being evaporated on the surface of the plant to stay connected to water molecules below them, and so they are pulled along.
