which process explains how rock that formed underground is now aboveground in sierra nevada
Answer:
formation process
Explanation:
farllon plate was fully subducted along pacific coast line
The cascade mountains formed from the igneous rocks by plate movement are younger and they are formed by the uplift of plates makes them appears aboveground in sierra Nevada.
What are cascade mountains in Sierra Nevada ?Since they were formed by melting above a subduction zone, the Cascades and Sierra Nevada's rocks are largely igneous. The Cascades, which initially arose 36 million years ago and are still forming now, are younger mountains.
In contrast, the Nevadan Orogeny, which occurred over 200 million years ago, is when the plutonic core of the Sierra Nevada started to form. When subducting at a sharp angle, oceanic lithosphere at the edge of the North American continent melted, and the magma surged back through the continental crust to form a volcanic arc.
The once-deep granite batholith that makes up today's Sierra Nevada was exposed by erosion after being raised by the North American plate. Although one small spur is located in Nevada, the elevated granitic intrusion is 640 kilometers long and largely located in California.

- All the metals of group 1 react with water, liberating hydrogen gas and forming metal
hydroxides. Suppose you are provided with a piece of metal stored in a bottle labelled as
‘Rubidium’. Based on your knowledge of the periodic table explain why it is not safe to
dispose it in sink with water?
Answer:
since it is in grp 1, it will react with water like all other metals.
Answer:
Rubidium, as a Group 1 metal, will have a strong reaction with the water and form hydrogen. The reaction is so strong it might even be explosive, hence the danger of putting it in water.

What transition energy corresponds to an absorption line at 527 nm?
Answer:
E = 3.77×10⁻¹⁹ J
Explanation:
Given data:
Wavelength of absorption line = 527 nm (527×10⁻⁹m)
Energy of absorption line = ?
Solution:
Formula:
E = hc/λ
h = planck's constant = 6.63×10⁻³⁴ Js
c = speed of wave = 3×10⁸ m/s
by putting values,
E = 6.63×10⁻³⁴ Js × 3×10⁸ m/s / 527×10⁻⁹m
E = 19.89×10⁻²⁶ Jm /527×10⁻⁹m
E = 0.0377×10⁻¹⁷ J

what is inert pair effect
Answer:
The inert pair effect is the tendency of the two electrons in the outermost atomic s-orbital to remain unshared in compounds of post-transition metals. The term inert pair effect is often used in relation to the increasing stability of oxidation states that are two less than the group valency for the heavier elements of groups 13, 14, 15 and 16. .[1] The name suggests that the outermost s electrons are more tightly bound to the nucleus in these atoms, and therefore more difficult to ionize or share

How many protons does a nitrogen atom have?
07
0 14
8
05
Answer:
07.
Explanation:
Answer:
7
Explanation:
We call these different isotopes of nitrogen. There are always 7 protons because the nucleus is always a nitrogen nucleus (Z=7). Since different isotopes of an element have different numbers of neutrons (but always the same number of protons) they have different mass numbers.

As a car slows down, its kinetic energy increases.
True
False
Answer:
False.
Explanation:
Kinetic energy represents the energy the car has and is using right now. So, if the car was fast, then it would have a lot of kinetic energy. A slow car has a low amount of kinetic energy.
When propane is reacted in the presence of oxygen gas, the products of this combustion reaction are: A. CO + H2O B. CO2 + H2O C. C2H4 + H2O D. CH4 + H2O
Answer:
B. CO2 + H2O
Explanation:
Propane is an hydrocarbon as it contains only v=carbon and hydrogen atoms.
Whenever an hydrocarbon reacts with oxygen or undergoes a combustion reaction, two products are always formed only,
These two products are;
Carbon dioxide (CO2) and water (H2O)
This means the correct option is option B.

What are the advantages of an electromagnet? PLEASE ANSWER!!
Answer:
The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field

What a higher or lower temperature make particles in a substance move faster
Answer/Explanation:
A higher temperature causes the molecules in a substance to move faster in a chemical change. This increased speed allows the particles to have enough force for a chemical change and it also increases the amount of times a particle hits another this makes it faster for it to combine.

The mass of an object is 32g and its density is 17g /mL. what is its volume
Explanation:
here,
Mass (m)= 32 g =0.32 kg
Density(d)= 17 g/ml
volume (v)=?
we know that,
d=m/v
17=0.32/v
v= 0.32/17
v=0.018
Answer:
[tex]\boxed {\boxed {\sf v \approx 1.88 \ mL}}[/tex]
Explanation:
The density formula is:
[tex]d=\frac{m}{v}[/tex]
If we rearrange the formula for volume, the result is:
[tex]v=\frac{m}{d}[/tex]
The mass of the object is 32 grams. The density is 17 grams per milliliter.
[tex]m= 32 \ g\\d= 17 \ g/mL[/tex]
Substitute the values into the formula.
[tex]v=\frac{32 \ g}{17 \ g/mL}[/tex]
Divide. Note that the grams, or g, will cancel each other out.
[tex]v=\frac{32 }{17 \ mL}[/tex]
[tex]v=1.88235294 \ mL[/tex]
Let's round to the nearest hundredth to make the answer more concise.
The 2 in the thousandth place tells us to leave the hundredth place as is.
[tex]v \approx 1.88 \ mL[/tex]
The volume of the object is about 1.88 milliliters.
