1. how does heat flow inside earth move the tectonic plates?
2. what effect does plate movement have on geologic events?
3. how does earth recycle tectonic plate material?

1, The force that causes most of the plate movement is thermal convection, where heat from the Earth's interior causes currents of hot rising magma and cooler sinking magma to flow, moving the plates of the crust along with them.

2, plate movement effects earthquakes,volcanoes, and tsunamis.

3, crustal recycling.

d. in sexual reproduction, offspring have more chromosomes than

either parent.

asexual reproduction results in offspring which are genetically the same as the parent organism (not counting a rare mutation). sexual reproduction produces a random mixture of the genetics derived from both parents
