Answer:
Change in plate tectonic leads to change in earth surfaces.
Plate tectonics have changed Earth’s surface over time because the earth surface is placed on these plate tectonics. Earth's outer surface is divided into various plates that slowly move over the mantle which changes Earth's surface over time by merging and separating of landmasses that turn into continents.
The movement of tectonic plates is responsible for the creation of landforms such as volcanoes and ridges. Some volcanoes are formed when the tectonic plates pull apart from one another whereas some volcanoes are produced when a tectonic plate slides over one another so we can conclude that change in plate tectonic leads to change in earth land forms.
Explanation:
1 Cal ---------- 4.184 J
? Cal ---------- 130.0 J
130.0 x 1 / 4.184 => 31.07 Cal

Answer:
1. Alpha particles consist of two protons and two neutrons.
Explanation:
Alpha particles are generally produced in the process of alpha decay, a radio active decay in which an atom loses an helium atom.
AN alpha particle is identical to the helium particle. The helium particle has mass number of 4 and atomic number of 2. This means;
Number of protons = 2
Number of neutrons = Mass Number - Atomic Number = 2
The correct option is option 1.
Since the pH of the substance is 5, the substance contains more of hydrogen ions.
<h3>What is pH of a solution?</h3>
The pH of a a solution is the negative logarithm to base ten of the hydrogen ions concentration of the solution.
![pH = -log[H^{+}]](https://tex.z-dn.net/?f=pH%20%3D%20-log%5BH%5E%7B%2B%7D%5D)
A neural solution has pH 7.
A solution with pH below 7 has more hydrogen ions while a solution with pH above 7 has more hydroxide ions.
The pH of a substance contains a hydrogen ion concentration of 1.0 x 10-5 M is 5.
Therefore, the substance contains more of hydrogen ions.
