Scientists use a system called Classification of Living Things, which categorizes each living organism into the following groups: Kingdom, Phylum, Class, Order, Family, Genus, and Species.
<h3><u>Answer;</u></h3>
D) <em>The more dense oceanic plate subducts under the less dense continental plate. Subducted plate melts due to heat and friction. Melted plate, now magma, rises up to the surface.</em>
<h3><u>Explanation</u>;</h3>
- <em><u>Volcanoes may be formed at convergent plate boundaries or at divergent plate boundaries. </u></em>
- <em><u>When two tectonic plates collide, they form a convergent plate boundary. Normally, one of the converging plates that is the dense oceanic plate will move beneath the other, which is the less dense continental plate a process as subduction. </u></em>
- <em><u>The friction between the plates in the subduction zone as a result of constant movement, melts the Earth's crust causing the underneath rocks to turn into magma.</u></em>
- <em><u>The magma creates great pressure and rises towards the surface of the earth, and on reaching the surface it is called lava, and a volcano is formed.</u></em>
3 examples would be touch, light and chemical.
and the most common signal would be chemical.
