1. floods can drastically change the land in an area due to
2. droughts are characterized by a prolonged lack of
3. fast moving land called can be caused by rainfall, human development in an area, or erosion to name a few.
4. a can be used to measure the intensity of an earthquake.

Explanation:

• For question 6: Floods carry water which has the power to erode and deposit sediments, changing the land.
• For question 7: Droughts are periods where there is a significant shortage of precipitation (rainfall, snowfall etc.).
• For question 8: Mudslides (or landslides) are fast - moving masses of land that can be triggered by rainfall (saturating the soil), human development (disturbing the land balance), or erosion.
• For question 9: A seismograph is an instrument that records the ground motion during an earthquake, and from these records, the intensity (among other aspects like magnitude) of an earthquake can be measured.

Answer:

1. erosion and deposition
2. precipitation
3. mudslides (or landslides)
4. seismograph
