How does energy from Earth’s interior affect surface changes?
Answer:
Energy produced deep inside Earth heats rock in the mantle. ... As it becomes less dense, the heated rock rises toward Earth's surface. The cooler, denser rock surrounding the heated rock sinks, as Figure 5 shows. In this way, heat inside Earth moves toward the cooler crust.
Explanation:

Energy from Earth’s interior affect surface changes due to:
Earth heat transport occurs by conduction, mantle convection, hydrothermal convection, and volcanic advection. Thus, about 99% of Earth's internal heat loss at the surface is by conduction through the crust, and mantle convection is the dominant control on heat transport from deep within the Earth.Tectonic processes and flow in Earth's interior drive deformation of Earth's surface that can lead to destructive earthquakes, tsunamis, and volcanic eruptions.Learn more:

Suppose that you take a sample of 500 g of ocean water and let the water evaporate. The mass of the remaining salts is 17 g. What was the salinity of the ocean water
Answer: The salinity of ocean water is 34 ppt.
Explanation:
Salinity is defined as the number of grams of salts present per kilogram of seawater. It is expressed in parts per thousand.
The formula used to calculate the salinity of ocean water or sea water is:
[tex]\text{ Parts per thousand}=\frac{\text{Mass of salts}}{\text{Mass of sea water}}\times 1000[/tex]
We are given:
Mass of salts = 17 g
Mass of sea water = 500 g
Putting values in above equation, we get:
[tex]\text{ Parts per thousand}=\frac{17g}{500g}\times 1000\\\\\text{ Parts per thousand}=34[/tex]
Hence, the salinity of ocean water is 34 ppt.
Adding oil to a table would ___________ the friction when sliding a book across it.
Increase or decrease
Answer:
Increase
Explanation:
Hope it helps you
Answer:
Decrease
Explanation:
If the oil you're referring to is just some normal oil, it'll lessen the friction and cause it to side more smoothly
The United States National Weather Service reports pressure in mm of Hg. What's the pressure of 725 mmHg in Pa, millibars, and Torr?
A. 101.325 Pa, 966 millibar, 725 Torr
B. 100,000 Pa, 1000 millibar, 760 Torr
C. 96,657 Pa, 966 millibar, 725 Torr
D.100.000 Pa, 760 millibar. 725 Torr
Answer:
C. 96,657 Pa, 966 millibar, 725 Torr
Explanation:
The pressure of 725 mmHg in Pa, millibars, and Torr is 96,657 Pa, 966 millibar, 725 Torr. Hence option C is correct.
What is pressure?Pressure is defined as the force that is applied perpendicularly to an object's surface in relation to the area that it is dispersed over. Pressure can actually be a very good thing. Stress only occurs and has a fully negative impact when it continues to grow and that sensation of serenity and order is replaced with one of being out of control.
Given pressure = 725 mmHg
1 mmHg = 133.32 Pa
725 mmHg = 133.32 x 725 Pa
= 96,657 Pa
1 mmHg = 1.333 millibar
725 mmHg = 725 x 1.333 millibar
= 966 millibar
1 mmHg = 1 torr
725 mmHg = 725 Torr
Thus, the pressure of 725 mmHg in Pa, millibars, and Torr is 96,657 Pa, 966 millibar, 725 Torr. Hence option C is correct.

Investigate: Press Reset. Start with 2.000 moles of sulfur, then press Start. How many atoms do you think this amount represents
Answer:
1.204428 * 10^24 atoms
Explanation:
Number of moles = 2 mol
Number of atoms = ?
The relationship between moles and atoms is given by the avogadro's umber. This is the number of units in one mole of a substance. The units can be atoms, ions etc In this case it is atoms. The number is equal to 6.02214076 * 10^23
This means;
1 mol = 6.02214076 * 10^23
2 mol = x
Upon solving for x,
x = 2 * 6.02214076 * 10^23
x = 12.04428 * 10^23
x = 1.204428 * 10^24 atoms
