Section 1
Weather Events Transform Landscapes Rapidly
Floods, fires, storms, and landslides can dramatically change the land in short periods. Heavy rain causes floods, while dry conditions lead to fires, both reshaping landscapes quickly.
In this Grade 4 lesson from Science: A Closer Look, Chapter 3, students explore how weather events such as floods, tornadoes, hurricanes, landslides, and avalanches cause rapid changes to Earth's surface. Students investigate how the steepness of a slope affects the movement of soil and rocks through a hands-on experiment, then apply inference skills to understand how erosion and deposition occur quickly during severe weather. The lesson builds core Earth science vocabulary and connects weather patterns to real-world land changes.
Section 1
Weather Events Transform Landscapes Rapidly
Floods, fires, storms, and landslides can dramatically change the land in short periods. Heavy rain causes floods, while dry conditions lead to fires, both reshaping landscapes quickly.
Section 2
Storms Rearrange Earth's Surface Features
Tornadoes create narrow paths of destruction, while hurricanes bring powerful winds and flooding over larger areas. Both storms can flatten buildings, uproot trees, and reshape ecosystems in a single day.
Section 3
Gravity Pulls Materials Downhill During Landslides
Landslides occur when heavy rains cause rocks and soil to slide down slopes. Similarly, avalanches happen when snow and ice rush down mountains, both events rapidly changing terrain.
Section 4
Rivers Deposit Materials During Floods
When rivers overflow, they carry soil and minerals to surrounding land. After floodwaters recede, these materials remain deposited on the land, providing nutrients that help plants grow.
