Answer: D
Explanation: it seem right to me I really don't know if this right but I hope this helps
Answer:
A. A volcano erupts on a small island.
C. Flooding loosens dirt and rocks along a hillside.
Explanation:
Tectonic activities and mass wasting will greatly lead to a change in land forms on earth's surface.
When a volcano erupts on a small island, a change in landform often results. Also, flooding can lead to changes in land form.
- Volcanic eruptions generally adds new materials to the earth surface.
- Magma that reaches the surface called lava deposits rock materials unto the surface.
- During an extensive period of flooding, materials are carried from one place to another and this greatly sculpts the surface of the earth.
Lol, I remember I helped my sister with this question but anyways, the card flew because of inertia and the quarter fell in the glass because of gravity :).
Answer:
hydrogen
Explanation:
pH is a measure of the ion concentration of hydrogen in a solution.
In chemistry, it literally means power of hydrogen ions and it is a measure of the molar concentration of hydrogen ions in a particular solution, thus specifying the acidity, neutrality or basicity of chemical solutions.
Mathematically, the pH of a solution is given by ![pH = -log 10[H^{+}]](https://tex.z-dn.net/?f=pH%20%3D%20-log%2010%5BH%5E%7B%2B%7D%5D)
Hence, a solution with a pH of 7 is neutral.
Also, a solution with a pH below 7 is acidic but basic if it's pH is above 7.
Answer: A difference in properties between two interacting systems as explained below.
Explanation: Planetary differentiation is the process of separation of different parts of a planetary body as a result of their physical or chemical behavior.
Causes for Physical Differentiation:
1. Melting and crystallization of source rock.
2. Differences in densities
3. Thermal diffusion
4. Collision of large bodies
Chemical Differentiation accounts for differences in chemical compositions of different materials.
The differentiation, or organization, of the Earth into layers led to the formation of a core, a crust, and eventually continents. The light elements were driven from the interior to form an ocean and atmosphere.
