A continental slope is the boundary between what to types of Earth's crust?
A Basalt and Sandstone
B Convergent and Divergent
C Continental and Oceanic
D Volcanic and Sedimentary
Answer:
c
Explanation:
I took the k12 test and got it right
A continental slope is a boundary between the Continental crust and Oceanic crust. Therefore, option (C) is correct.
What is a continental slope?A continental slope can be described as the slope between the outer edge of the continental shelf and the deep ocean floor. The continental slope is defined as a cut by submarine canyons in many locations and marks the seaward edge of the continental shelf.
Continental slopes follow the boundary between continental and oceanic crust. The Continental slope has a steepness range from 1 to 25 degrees, the average is 4 degrees.
The continental margin lies between the continental shelf and the abyssal plain and comprises a continental slope that is surrounded by the flatter continental rise. It contains thick sediments deposited by currents from the shelf and slope.
The shelf generally ends at a point of increasing slope known as the shelf break and the sea floor under the break is the continental slope.

If 10 milliliters of liquid has a mass of 70 grams, what is its density?
O 7 g/mL
70 g/mL
0.7 g/mL
700 g/mL
Answer:
The answer is 7 g/mLExplanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 70 g
volume = 10 mL
We have
[tex]density = \frac{70}{10} \\ [/tex]
We have the final answer as
7 g/mLHope this helps you
Why is there so much heat released following a combination reaction
Answer: When a combination reaction occurs between a metal and a non-metal the product is an ionic solid.
Explanation: Another hint(s): When magnesium burns in air, the atoms of the metal combine with the gas oxygen to produce magnesium oxide. This specific combination reaction produces the bright flame generated by flares.
When the wedges are removed, predict which way the carts will move. Justify your prediction.
Answer:
I believe the carts will move towards each other, as positive and negative charges attract each other.
Explanation:
It is like a magnet when you put the opposite sides together. (North and South, South and North) or the plus goes to the minus and the minus goes to the plus.
If you take out the far left and right wedges, it may move a little away for a few seconds, but will move back together .
Another hypothesis is that if the sheets are flimsy, the sheets will attract each other, however, the sheets will join together at the top, but the carts will still stay at the same place.

How is a controlled experiment performed?
What strategies are involved in solving a science problem?
Answer:
In a controlled experiment, an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled. State what steps you will take to design an experiment to test your hypothesis. Complete the experiment. Make observations. Record what happened during your experiment.

Who would most likely be required to work with sodium hydroxide?
a plumber
a gardener
a bricklayer
a mechanic
Need answer ASAP
Sodium hydroxide NaOH is proven to be an active agent for improving the mechanical properties of the bricks. Hence, bricklayer most likely need sodium hydroxide.
What is sodium hydroxide?Sodium hydroxide is an ionic compound formed by the metallic sodium and water. Sodium hydroxide has the chemical formula NaOH. It is a strong base and used as a reagent in many chemical synthesis which has to be carried in presence of a base.
Sodium hydroxide has an effect on the drying kinetics of bricks which are made with clay. Studies reported that the drying duration is linearly related with the concentration of NaOH.
Drying duration of bricks layers increases with increase in concentration of NaOH as well as the material porosity decreases. and hence the bricks will not show the visible cracks. Therefore, bricklayer need NaOH.

1. A student measures the height of a small lamp to be 32cm. According to the factory specifications,
the lamp is actually 30cm. What is the percent error of the student's measurement?
Answer:
6.67 %
Explanation:
Given that,
Measured height of a small lamp, l = 32 cm
Actual height, l' = 30 cm
We need to find the percent error of the student's measurement. Percent error is given by :
[tex]\%=\dfrac{|l-l'|}{l'}\times 100[/tex]
Putting all the values, we get :
[tex]\%=\dfrac{|32-30|}{30}\times 100\\\\\%=\dfrac{2}{30}\times 100\\\\\%=6.67\%[/tex]
So, the percent error of the student's measurement is 6.67 %.

How many grams of Sodium will have the same number of atoms as 6 grams of Magnesium?
Atomic mass of Sodium is 23 u and atomic mass of Magnesium is 24 u.
Answer:
92gm
Explanation:
Atomic mass of Mg=24g=1 mole of Mg
∴ 24g =1 mole of Mg contain 6.022×10^23 atom
∴ 6gm contains 246.022×1023×6
=4×6.022×10^23 atoms
Now according to question, there are 6.022×1023 atoms of Na
23gm of Na contains 6.022×10^23 atoms
∴6.022×4×10^23 atoms of Na weighs 23×6.022×10^23×4/6.022×10^23⇒92gm
