Explanation:
- Mechanical weathering involves the breakdown of the rocks into small pieces by the external support such as pressure whereas Chemical weathering involves the breakdown of the rocks takes place by the chemical process.
- Mechanical weathering is a physical change that is caused by the movement of wind and water whereas chemical weathering takes place when the chemicals present in the air or water get mixed with minerals or rocks.
- Mechanical weathering involves:
Abrasion, freezing, thawing, exfoliation.
- Whereas Chemical weathering involves:
dissolution, oxidation, carbonation, hydrolysis.
Answer:
it from the planet is 4.51 unit
Explanation:
given data
time t1 = 7 days
distance a1= 5.0 units
time t2 = 6 days
to find out
How far is it from the planet
solution
we know that from Kepler second law of planetary motion
T² is directly proportional to a³
so T² = K a³ ...........1
here for for both time we can say
a2³ = a1³ × 
a2³ = 5³ × 
a2³ = 4.51 unit
so it from the planet is 4.51 unit
This is correct the magma benethe the crust moves the plates
