If the lithosphere is resting on the asthenosphere and you put a lot of
statuscvo [17]

Answer:

Explanation:

Can you think of a solid that can flow?

You use one twice a day! Toothpaste is a solid that can flow. Is the asthenosphere made of toothpaste? Only if the

toothpaste is ultramafic in composition, and then it would only be able to flow if it were really, really hot. Still the

toothpaste analogy gives you a good image of how the asthenosphere might behave if you squeezed it!

Lithosphere

The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid

solid. The lithosphere is the outermost mechanical layer, which behaves as a brittle, rigid solid. The lithosphere is

about 100 kilometers thick. How are crust and lithosphere different from each other?

Which characteristics can be used to classify the tree as a gymnosperm rather than “any other type of seed” plant?
erica [24]
1. Naked Seeds, Gymnosperm means 'naked seed' and these were the earliest trees to evolve. They do not produce flowers and have seeds which are directly exposed to the air for wind pollination. Pine cones are one example. For ease you might think of the gymnosperms as conifers, such as yew and Scots pine.

Which statements accurately describe soil? Check all that apply.
ahrayia [7]

Answer:

Soil condition directly affects crop growth.

Explanation:

Soil condition affects the crop growth directly. If a soil is in fertile condition then the growth of crop which is growing in such soil will be good but if the soil is infertile then the crop will not grow to its fullest. A fertile soil is the one which has optimum condition for growth of a crop like suitable pH, moisture retention capacity, good amount of nutrients & minerals like nitrogen, phosphorus, sodium, potassium, magnesium etc. If a soil is rich in all these constituents then the crop which is growing in this soil will be healthy. But, if a soil is infertile then the crop which is growing on that soil will be under stress and will not be able to grow completely.
