[math]W sin(slope) + H cos(slope) = true thickness[/math]
[math]24 sin(14) + 18 cos(14)[/math]
[math]23+2[/math]
[math]26[/math] (with sig figs)
EDIT: Just realised my calculator was on radians, not degrees
Using degrees, I got the same thing you did, so you can probably ask a question now

Yes I meant 24 meters, you needed to convert. pikachu4919 is correct (36.514ft, idc about sig figs). Your turn!

Pretending you are part of the USGS and giving a presentation to eager 3rd graders, provide three examples of geohazards, how each of them can be caused, and one safety measure you would recommend for each of the examples you provide.

Earthquake: Caused by tectonic plates, faults, and other large-scale rock movement; buildings can be built safer, and seismologists can predict when one will occur
Subsidence: Caused by changes in groundwater level, faulting, mining, earthquakes, various other geologic events/processes. Safety measures: more careful mining and groundwater extraction, prediction of faulting events and earthquakes
Landslide: Caused by earthquakes, groundwater level changes, deforestation, erosion. Safety measures: taking a good geologic survey of the area before deforestation, not removing too much groundwater.

Nice! Your turn!

Name the two supercontinents that formed after pangea split during the triassic and jurassic.

Since no one's posted a question in a while,
1. Alfred Wegener used which of the following pieces of evidence to prove his theory of continental drift? (Select all that apply)
a) Matching coastlines of continents now separated by oceans.
b) Evidence of glaciers in areas that are now tropical.
c) The composition of meteors from outer space.
d) The diversity of species of fossils, especially those of dinosaurs and
mammals.
e) The pattern of similar mountain belts on different continents.
2. However, what crucial part of the theory was Wegener unable to prove?
