Answer:

1. Tectonic activity is responsible for some of Earth's most dramatic geologic events: earthquakes, volcanoes and deep ocean trenches can all be formed by tectonic activity in the lithosphere.

2.The lithosphere can affect the atmosphere when tectonic plates move and cause an eruption, where magma below spews up as lava above. This can also release copious amounts of volcanic ash or soot, which pollutes the atmosphere, blocks radiation and creates a cooling effect.

3. I don't know what's show on the text sorry that parts up to you good luck :)

The historical walking tour of a town covers a total distance of 5 miles. The map shows that the path of the tour travels 3 inch
kari74 [83]
Since the problem is given all the total walking distance, the first thing we are going to do is find the total distance in the map:
Diastance_{map}=3+4+2+1
Distance_{map}=10
Now that we have the distance in the map, we can establish a ratio between the walking distance and the distance in the map:
\frac{5miles}{10inches} = 0.5 \frac{mile}{inch}

We can conclude that each inch the map represents 0.5 miles of walking distance.
