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:
All of the above is true about the waxing gibbous and waning gibbous moon.
Explanation:
The first option is correct because the waxing gibbous moon is lit up on the right, with the moon moving into full moon phase next, and then being followed by a phase where it is lit up on the left, known as the gibbous waning moon.
The second option is correct because the moon moves from the waxing gibbous phase toward the full moon phase, it is becoming more and more lit up, thus it gains light, while the waning gibbous moon phase comes after the full moon phase where it is becoming less and less lit up, thus loses light.
The third option is correct because the lit up part of the moon in both of these phases has an elliptical shape, with the elongated part being on the top and bottom side, thus giving it an appearance like a football.
Geography uses other subject in it's studies. Very close to geography are geophysics and geology. Geophysics studies quantitatively physical phenomena of the planet Earth, geology studies composition of soil rocks and their development through history. Geography uses biology, statistics, mathematics and other subjects in order to better describe the Earth.
Answer:
can you send a picture of this question, because I can't read all the answers.
<h2><u>Answer:</u></h2>
For the right triangle to be given in name of three letters such as this, the right angle is most likely to be in the center, in this case letter K. To determine the common trigonometric properties of a certain angle we may use of the mnemonics SOH - CAH - TOA.
sin angle = opposite side / hypotenuse
cosine angle = adjacent side / hypotenuse
tangent angle = opposite side / adjacent side
If we let small letter j, k, and l be the sides opposite to angles J, K, and L, respectively. Then, the cos (L) will be,
cos (L) = j/k
