Why do earthquakes often cause damaging fires? tsunamis from earthquakes generate enough heat to start fires. magma from deep underground escapes through faults. seismic waves can break gas lines, water lines, and electrical lines.

The correct answer is c) Seismic waves can break gas lines, water lines, and electrical lines.

Explanation:

Earthquakes are produced by the strong movement of the earth, which is caused by sudden releases of accumulated energy for a long time, after changes in tectonic plates.

The dimensions of earthquakes are different between each one; some are very strong, and others of lesser strength. Therefore, depending on the power of the earthquake, this will be the effect of it. For example, when it is of one dimension, there may be fires, landslides, and thousands of buildings and houses lost, and many times human losses.

For these reasons, earthquakes can cause fires because, depending on their magnitude, they can cause short circuits or gas explosions.

I hope this information can help you.

the earth’s crust is broken into separate pieces called tectonic plates (fig. 7.14). recall that the crust is the solid, rocky, outer shell of the planet. it is composed of two distinctly different types of material: the less-dense continental crust and the more-dense oceanic crust. both types of crust rest atop solid, upper mantle material. the upper mantle, in turn, floats on a denser layer of lower mantle that is much like thick molten tar.

each tectonic plate is free-floating and can move independently. earthquakes and volcanoes are the direct result of the movement of tectonic plates at fault lines. the term fault is used to describe the boundary between tectonic plates. most of the earthquakes and volcanoes around the pacific ocean basin—a pattern known as the “ring of fire”—are due to the movement of tectonic plates in this region. other observable results of short-term plate movement include the gradual widening of the great rift lakes in eastern africa and the rising of the himalayan mountain range. the motion of plates can be described in four general patterns:

collision: when two continental plates are shoved together

subduction: when one plate plunges beneath another (fig. 7.15)

spreading: when two plates are pushed apart (fig. 7.15)

transform faulting: when two plates slide past each other (fig. 7.15)

the answer is d.index
