Rocks are heated, metamorphosed, melted, weathered, sediment is transported, deposited and lithified, then it may be metamorphosed again in yet another cycle. This recycling of the material of the Earth's crust has been going on for billions of years, as far back as there is a preserved geologic record (about 4 billion years). Weathering and erosion at the Earth's surface can break down rocks into small bits. These can be deposited as sediments that become sedimentary rocks. Burial, with rising pressure and temperature, can alter sedimentary (as well as any other) rocks to form metamorphic rocks. Continued rise in temperature can eventually melt rocks and produce magma. Cooling of magmas leads to igneous rocks, etc.

Answer:

be able to meet long term timber needs.

Explanation:

Forest Services has been indicated for a long time the exhaustion of timer in the United States. However, in the recent decade, this trend has shown a reverse. The creation of nuclear energy and other technological developments that bring about drastic changes in our way of life. Gradually, the forest has recovered its trees and plants, and it is anticipated that timber will be available to meet long-term wood needs.

You are pushing a box with 20 N of force that has<br> a mass of 10 kg, solve for acceleration

insens350 [35]

Answer:

Force=mass ×acceleration.

20=10×acceleration.

20=10a.

a=2m/s^2.

Answer:

If we use a thick foil, then more α particles would bounce back, and no idea about the location of positive mass in the atom would be available with such certainty.

Determine the ph of a 0. 35 m aqueous solution of CH3NH2 (methylamine). The kb of methylamine is?

guajiro [1.7K]

The pH of 0.35 M of CH₃NH₂ is 12.09 and the $k_b$ for methylamine is 4.4 x 10⁻⁴.

pHis the quantitative measure of acidity and basicity of an aqueous or other liquid solution. The scale range goes from 0 to 14. Water has a pH of 7 and is neutral in nature.
