How do you calculate the percent slope of a mountain?

Back

Percent slope is calculated by dividing the vertical rise by the horizontal distance and multiplying by 100.

Front

What is the percent slope of a mountain that rises from 380 m to 590 m over a horizontal distance of 3,000 m?

Back

7%.

Front

What are the main types of mass wasting events?

Back

Front

What factors can trigger a landslide?

Back

Factors that can trigger a landslide include heavy rainfall, earthquakes, volcanic activity, and human activities such as construction.

Front

What is the difference between a landslide and a rockfall?

Back

A landslide involves the movement of a large mass of soil and rock, while a rockfall specifically refers to the rapid descent of individual rocks.

Front

What role does vegetation play in preventing landslides?

Back

Vegetation helps to stabilize soil with its root systems, reducing the likelihood of landslides.
