Whole mantle convection can take millions to billions of years to complete a full cycle. The process involves the slow movement of mantle material due to heat from the Earth's core and the cooling of the upper mantle and crust. Depending on the specific conditions and dynamics of the mantle, the cycle's duration can vary significantly. Generally, estimates suggest that a complete mantle convection cycle might take around 100 million to 200 million years.
Peridot is typically formed deep within the Earth's mantle and brought to the surface through volcanic activity. The process can take millions of years, as it requires specific geological conditions such as high pressure and heat to create peridot crystals.
Scientists can learn about Earth's mantle through seismic studies that analyze how seismic waves travel through the mantle, laboratory experiments that simulate mantle conditions, and by studying rare mantle-derived rocks that reach the Earth's surface through volcanic eruptions.
Mantle was born in 1931 and died in 1995.
Water enters the mantle cavity through an incurrent siphon, and exits the mantle through an ex current siphon. This is a normal aspect of biology.
A snail's organs are attached to the shell through the mantle. If you attempt to pull the snail out, it will harm it.
Yes, S-waves can travel through the Earth's mantle. They are secondary seismic waves that propagate by shearing the material they pass through, making them able to travel through solid materials like the mantle. However, their velocity and amplitude might change as they move through the different layers of the Earth.
The shell is secreted by the mantle.
Hot mantle rock rises where the plates are moving apart. This releases pressure on the mantle, which lowers its melting temperature. Lava erupts through long cracks in the ground, or fissures
They can do this by how and how quickly seismic waves can move through the mantle.

The moons heat does pass through the mantle but it hardly makes heat. its is mostly cold day and night.
