Ineed on earth science !
1.which of the following statements about uniformitarianism is correct?

a. geological processes occurring today have always occurred in the past.
b. geological processes have changed throughout the earth's history.
c. features on the earth's surface formed as they appear today and have never changed.
d. geological processes have stopped completely at different points in time.

2.what tests were able to determine when continental crust was formed?

a. stratigraphic measurement and argon-aluminum dating
b. stratigraphic measurement and strontium-rubidium dating
c. potassium-argon dating and half-life isotopes
d. relative dating and carbon-prototyping

3.why is open pit mining so devastating to the environment?
( cant be 'c' already tried it)
a. it completely removes any available topsoil.
b. it causes massive erosion of sand.
c. it releases a lot of carbon dioxide into the air.
d. it exposes dangerous chemicals buried in the earth's crust.

1. A.

2.D.

3.B.

Explanation:

Notepad:  

A. The present is key to the past. The geological processes ocurring today have always  ocurred in the past. So if we want to predict what is going to happen in the future,  we need to understand the Earth's past.  

B. The tests that are used to determine when continental crust was formed are the relative dating and carbon prototyping

C. Open pit mining, this type of mining is very damaging to the environment because strategic minerals are often only available in small concentrations,  which increases the amount of ore needed to be mined.

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.
