The <u>innermost core</u> is the immovable object in a supernova explosion.
<h3>
What is Supernova?</h3>
- The enormous and dazzling explosion of a star is known as a supernova.
- This sporadic astronomical event occurs either when a white dwarf is sent off into uncontrollable nuclear fusion or in the latter stages of the formation of a massive star.
- The initial object referred to as the progenitor either entirely vaporizes or falls into a neutron star or black hole.
- A supernova's peak optical luminosity can be comparable to that of an entire galaxy before diminishing over the course of a few weeks or months.
- The most recent supernova remains have been found, although Kepler's Supernova, which happened in 1604, was the last one in the Milky Way that could be directly observed.

Some people consider the Earth to be alive because of its dynamic processes or cycles. Biogeochemical cycle is the turnover of different substances in the Earth and occur in different parts of the Earth like in the biosphere, lithosphere, atmosphere and hyrdosphere. Biogeochemical cycles help keep the Earth warm, recycle essential materials and is vital (or are needed) to living things.
The image shows the Convergent plate boundary.
<u>Explanation:
</u>
Convergent boundaries occur wherever the Earth’s tectonic plates move or collide toward each other.
As the plates converge, the denser, thinner tectonic plate sub-ducts or dives beneath the lighter, thicker, more buoyant tectonic plate.
As shown in the picture, the plates are composed of rigid lithosphere consisting of the crust of the earth and the uppermost mantle. Movement of the plates is driven by convection in the asthenosphere and lower mantle, which are softer and warmer than the lithosphere and can flow on geologic timescales. Convection is fuelled by heat generated from radioactive decay of elements in the Earth.
