Biological weathering is caused by living organisms, such as microbes, animals, and plants. Water, oxygen, and rocks are nonliving things (though water and rocks may be capable of weathering), and only plant roots fits the definition of biological weathering. So the correct answer for #1 is A.
Frost wedging occurs when the little water content in rock freezes, expanding and forcing the rock apart. Eventually, enough freeze-melt cycles causes the rock to break apart little by little. This is due to ice's density being less than that of water, meaning that it is because water expands when frozen. So the answer to #2 is A.
My name is jeff and idk about the answer
Answer:
The Moon's phases repeat every 29.5 days, but it's orbit around the Earth only takes 27.
Explanation:
Why? In that time, as our Moon moves around Earth, the Earth also moves around the Sun. Our Moon must travel a little farther in its path to make up for the added distance and complete its phase cycle.
They are found in the tundra regions of Eastern and central Europe. Mostly covered in permafrost, in some areas this frost has melted. The Drunken forest is the reference to the shallowness of where the trees roots are and then the trees start to tip over (Like a drunk man LOL). But within the Northern Hemisphere it alters the life around it and also destroys roads and buildings
It is only logical that mountain ranges form natural watershed boundaries because <u>water </u><u>from </u><u>rain </u><u>and </u><u>melting snow </u><u>flow to the </u><u>river</u>s.
<h3>Sources of Water for rivers. </h3>
- Rainfall and the resulting runoff.
- Water from natural ice.
Both of these come down from mountains and will be impacted by gravity to keep flowing downwards. This then forms or contributes to rivers and explains why mountains are generally next to watersheds.
