Why do erosional landforms occur more often in the cooler seasons?
Leona [35]
Erosional landforms occur more often in the colder periods of the year because in this parts of the year there's usually more rain, and also there's snow ,and most importantly ice. The rain and snow contribute to the chemical decomposition of the rocks, while the ice with it's pressure contributes to the physical decomposition of the rocks, by literary increasing it's volume inside the cracks of the rocks and break them from the inside.

Suppose that two stars in a binary star system are separated by a distance of 80 million kilometers and are located at a distanc
jonny [76]

Answer: 1) Angular separation equals 0.0000031 degrees

2) Angular separation in arc -seconds equals 0.011156"

Explanation:

For 2 stars separated by a distance 'S' and at a distance 'D' from the earth the angular separation in radians is given

\theta _{rad}=\frac{S}{D}

Applying values we get

\theta _{rad}=\frac{80\times 10^{6}}{150\times 9.46\times 10^{12}}\\\\\therefore \theta _{rad}=\frac{1}{18487500}radians

Now we know that 'π' radians equals 180 degrees thus the above value in degrees shall be equal to

\therefore \theta _{degrees}=\frac{1}{18487500\times \pi }\times 180^{o}=0.0000031^{o}

2)

The angular separation in arc- seconds is given by

\theta ''=\theta ^{o}\times 3600\\\\\theta'' = 0.0000031\times 3600=0.011156"
