How Landforms Change Over Time

A Journey Through Earth's Changing Surface Grade 2 Science

What Are Landforms?

Hills and mountains that reach high Valleys that dip down low Rivers that flow through the land Beaches by the ocean

Do Landforms Always Stay the Same?

Think about your favorite outdoor place Has it ever looked different after a big storm?

Natural Forces That Change Land

Water from rain and rivers Wind that blows sand and soil Ice that freezes and melts These forces work slowly over time

Let's Do an Experiment!

We'll build a mini landform Then make it 'rain' to see changes Watch carefully what happens Be ready to describe what you see

Erosion in Action

Changes Can Be Fast or Slow

{"left":"Slow changes happen over many years\nMountains grow taller very slowly\nRivers carve valleys bit by bit","right":"Fast changes happen quickly\nLandslides move lots of rock at once\nFloods can change riverbanks in one day"}

Remember This!

Landforms change over time because of natural forces like water, wind, and ice. Sometimes changes are slow, sometimes they're fast, but Earth is always changing!
