Can you guess the title of my next video?

Write your guess in the comments section below.

Beneath our feet, thousands of tree roots
are connected to one another by fungi.

Whose roots penetrate and spread into the ground.

They form a network called mycorrhizal network.

Through which trees send chemical signals and talk to each other.

Big mother trees called Hubs send nourishment to smaller plants, helping them grow.

Also, a dying tree deposits its resources
in the network for other trees to use.

Several natural processes make ocean water salty.

For example, when it rains, the water droplets react with carbon dioxide in the atmosphere.

Form carbonic acid, making rainwater slightly acidic.

This acidic rainwater reacts with minerals present in the rocks and forms new minerals and salts.

These minerals and salts are then carried
by flowing water to the oceans.

In addition to this, along the mid-ocean ridges, magma rises close to the oceanic crust.

Here, when the salty ocean water seeps into the earth's crust, it gets hot due to magma.

This hot water dissolves more minerals present in the crust.

Carries them to the oceans through fissures called hydrothermal vents.

Air pressure is the weight of air pressing
down on earth and all other objects present on it.

Now, when a straw is in a liquid, the air
pressure upon the liquid in the glass.

The air pressure upon the liquid in the straw is similar.

Causing the levels of liquid to be almost equal.

However, when we drink the liquid through
straw.

We first inhale causing the air from the straw to flow into our lungs.

Now due to the absence of air, the air pressure in the straw decreases.

Hence, the air pressure present on the liquid of the glass pushes the liquid into the straw.

Causing it to move upwards and thus, helping us drink.

Bones are one of the most important parts
of our body.

They not only provide structural support but also produce red blood cells.

Hence, when we crack or break a bone, it is
very important to heal it.

In the healing process, cells called chondrocytes produce collagen which forms cartilage.

This cartilage bridges the gap between the
broken bones, thus producing a soft callus.

Then, special cells called osteoblasts create a hard bony callus using collagen.

And minerals like calcium and phosphorus, thus forming our new bone.

However, this new bone is irregular in shape.

Hence, cells called osteoclasts start remodelling the bone.

Resulting in the formation of bone similar to the original shape.

Vertigo is not necessarily fear of heights.

In medical terms, vertigo refers to a false
sensation of movement due to which we feel dizzy.

The most common type of vertigo is Benign Paroxysmal Positional Vertigo or BPPV.

It is caused when our inner ear which helps
us maintain balance by detecting motion.

And position of our body, doesn't function properly.

Normally, when we move our head, the cilia and calcium crystals in our inner ear move.

Thus sending signals to the brain about our movement.

However, sometimes some crystals dislodge and move into the fluid-filled semicircular canals.

Now, when we move our head, the crystals move along with the fluid.

However, even after our head movement has stopped, the crystals keep moving in the canals.

Thus sending wrong signals to the brain that our head is still moving.

Due to this wrong information, the person gets a false sensation of movement which makes him feel dizzy.
