the motion of particles in different states is difficult to observe. a student used computer software to represent the movement of particles in the solid state. which type of scientific model did the student use?

a simulation because it imitates an intrinsic process in the molecule.
a simulation because it visualize the orientation of atoms in the molecule.
a 3-dimensional model because it visualize the orientation of atoms in the molecule.
a 3-dimensional model because it imitates an intrinsic process in the molecule.

I think that is might be the last one, I'm not all that sure though

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
