What are three ways that rocks can break into smaller pieces?
When someone pushes rocks onto grass and the grass makes it break into smaller pieces
When seeds get into the cracks and then the seeds start to grow and that causes the rock to break...root wedging
When rocks get rained on and they get smooshed into the ground.
When ice gets into the cracks and then the ice freezes and breaks the rock...ice wedging

No, a mountain won't last forever. Thunder and lightning can make it crumble.
Yes, a mountain will last forever. Rocks can never break apart.
No, a mountain won't last forever. Ice wedging and root wedging break rock apart.
Why do cone volcanoes explode?
They have thin lava that releases the air bubbles.
They have thick lava that releases the air bubbles.
They have thick lava that traps the bubbles and creates pressure, causing an explosion.
They have thin lava that traps the bubbles and creates pressure, causing an explosion.
By looking, how can you tell the difference between volcanoes that explode and those that don't?

What is the difference between felsite and basalt lava?
Felsite is light-colored. Basalt is black.
Basalt is light-colored. Felsite is black.
What is ice wedging?
Ice wedging is when a soda can explodes.
Water freezes in cracks of rocks and expands, breaking the rocks apart.
When ice in your cup is stuck and won't come out.
Ice melts in cracks of rocks and shrinks, breaking the rocks apart.
What is root wedging?
Seeds fall in cracks of rocks. The roots grow and break the rock apart.
Tree roots wedge themselves into each other.
Gardners cut roots to get them to grow better.
Rocks fall in the roots of plants and break the plants apart.
What causes landslides?
sun
not enough rain or water
forest fires
rain or water
What is a landslide?
a fault in the Earth
when rocks or mud slide down a slope
when rocks or mud stay where they are
rocks or mud moving in a flat area
