this immense mountain range began to form between 40 and 50 million years ago, when two large landmasses, india and eurasia, driven by plate movement, collided. because both these continental landmasses have about the same density, one plate could not be subducted under the other. the pressure of the impinging plates could only be relieved by thrusting skyward, and forming the mountains.

a) eurasian
b) himalaya
c) rocky
d) ural

if I remember correctly it was a and c

i going by what my sister did yesterday I think she got it right

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.

the "power" of a lens is its resolution power, or its ability to distinguish between to closely located points. with the low power lens, it is likely you will see the rough form of the hay and maybe some movement of dots around the hay. however, when observed with the high power lens, the detailed features of the hay become visible and the microbes being grown are more clearly visible.

i hope this you
