A plant takes root in a small crevice of rock, as the plant grows, its roots push on the edges of the rock, breaking it is a form of weathering? 1. True

2. False

True

Step-by-step explanation:

Roots grow into cracks in the rocks, as the roots grow, they press on the sides of the crack, making it wider until it breaks apart (example - tree roots breaking up the sidewalk. Mechanical weathering is the process of breaking big rocks into little ones. This process usually happens near the surface of the planet. Temperature also affects the land. The cool nights and hot days always cause things to expand and contract. That movement can cause rocks to crack and break apart.

The density of water is 1 g/cm cubed and in order for the pebble to sink its density has to be greater than the density of water and in order for the twig to float its density has to be less than the density of water
