Answer:
Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated. ... As a result, the particles take up more volume.
Answer:The solid is less dense than the liquid
Explanation:
Ice is less dense than water because of the crevices or spaces in the lattice structure of ice. Liquid water has a much greater density than solid water because its molecules are more compactly packed than in ice. Ice has large spaces between the hydrogen bonded water molecules hence less density than the liquid. Being less dense than !liquid water, it floats on water.
Answer:
It is formed when magma is trapped deep inside the Earth.
Explanation:
Intrusive or plutonic, igneous rock forms when magma is trapped deep inside the Earth.
medium grained rocks ( crystal 2mm to 5mm) coarse grained rocks with crystal over 5mm in size.
The big bang; that's what most scientists think.
Answer:
Biotic factor
Explanation:
Competition only exist due to limited resources (abiotic factors AKA environment) which occurs in biotic factors (living organisms).
Fear factor is nonsense because fear does not exist in plants but they still compete for sunlight and water.
Factory factor is nonsense as well because this term does not exist in biology.
