Tsunami waves are caused by earthquakes in the ocean floor. As the waves approach the shore, they usually grow in height. When this occurs, which aspect of the wave is changing? A. amplitude
B. direction
C. frequency
D. speed
E. wavelength

No because scientist are still changing there mines today so they are not correct to this day

When seismic waves hit a fault, the waves are reflected off the fault. seismograph can detect these reflected seismic waves. geologists then use these data to map the fault's length and depth

Iassume the answer is 75 feet. inwards to outwards rather than outwards to inwards. probably be 75.hachures are stokes drawn in direction of the steepest slope. a series of short parallel lines drawn on a map to indicate topographic relief. it is actually called hachures on contour lines. the small marks in the center of the feature are called hachures.observe the picture attached
