Imagine you are part of a group of engineers who need to test a scale model of a footbridge. It will be a 1/20th scale model of the bridge. The footbridge will cross over a busy road and allow people to cross the road safely. How could a relatively small design error of 2 centimeters in the model system cause a significant problem in construction of the bridge? What if it was an error of 4 centimeters? (HINT: Create a ratio table.) Please explain your answer. PLS HELP ME

Much of the general structure and physical properties of the interior of the earth are inferred from: a)deep oil and gas bore holes b)geologic investigations c)analysis of seismic waves d) study of volcanoes

Rocks, as they are compressed, begin forming mountains above the earth's surface when two continental plates converge. the continental crust increases in depth as the mountains grow above. the himalayan mountains formed at a convergent plate boundary in this manner. the rocks are smashed together causing them to due to the intense heat and pressure from the colliding plates and eventually forming rock. a) melt; igneous b) layer; sedimentary c) recrystallize; metamorphic d) melt into the earth's interior; metamorphic
