Trenches and landslides occur
Large cracks and volcanic activity occur
Earthquakes and landslides occur
2
At convergent plate boundaries...
Plates move apart, and mid-ocean ridges form
Plates slide along each other, and mountains form
Plates move towards each other, and mid-ocean ridges form

3

core
inner layer
outer layer
mantle
5
What can be formed at a convergent plate boundary?
