What is plant action?
plant roots can grow in cracks rocks. as they grow they break apart the rock.
What part of a growing plant can put enough pressure on some kinds of rocks to break the rock apart?
A metal or a bigger rock than the composed one.
What does a plant do to break a rock into pieces?
Plant root growth penetrates small cracks and crevices in rock and spreads them further apart, fracturing them and making them more vulnerable to chemical weathering. Other plants can attack the surface of rock directly, extracting nutrients.
How can plants chemically change rocks into soil?
Well, first the plant can eat the rock and digestion will break it down. Or, the plant can throw it into outer space where it will explode from gassy bubbles.
How can a tree break a rock apart?
The roots of the tree break into the rock.
Can a plant break a rock a part?
Yes, by erosion or by its roots.
What is plant action?
plant roots can grow in cracks rocks. as they grow they break apart the rock.
Explain the difference between cleavage and fracture.?
Cleavage is when you can break the rock into square like pieces and Fracture is when you break a rock into uneven different shaped pieces.
How are ice and plant roots weathering agents?
They expand within cracks in rock to break the rock apart
How can a plant can break a rock?
a plant has roots right? So when the plant is inside a crack of a rock and starts growing, the crack is opened up further until finally the rock breaks. This is generally not a very effective mechanism.
Explain and give examples of the ways in which soil is formed.?
One way in which soil is formed is from the weathering of rock. When water and wind break down rock, particles from the rock are turned into soil. Also, the decomposition of plant remains turn into soil because after the plant remains have been eroded, those parts or particles turn into soil. It's the same with animal remains, too.
Why are large rocks broken into smaller pieces by plants?
because the roots of the plant break down rock (by forsing it 2 break)
Explain how rock and mountains break apart?
Rocks and mountains break apart due to erosion or weathering. The rocks and mountains would break down into smaller and smaller pieces and fall away.
How do plant roots break apart rocks?
Mechanical weathering.
What natural event could have caused something as hard as a rock to break?
Any form of mechanical weathering causes rock to break into smaller pieces. A landslide will definitely cause rock to break. Meteor impact, plant root growth, ice wedging, and the movement of animals will also cause weathering.
