Because since P waves always come first surface and S waves come after.
Convection currents in Earth's mantle are caused by the rise of hot material rising towards the crust, becoming cooler and sinking back down. This process occurs repeatedly, causing the currents to constantly flow. The movement of the currents plays a factor in the movement of the mantle.
Answer:
True or False
Answer - True
Explanation:
The mantle convection clearly describes how the mantle moves, transferring heat from the white-hot core to the lithosphere. The mantle is usually being heated below and the cooling happens above and the general temperature of the area gets dropped over a long period of time.
Hot buoyant Magma is being transferred through convection currents, to the lithosphere at the plate boundaries and hot spots. Also, convection current moves cooler materials from the crust to the interior of the earth through a process that is widely known as subduction.
1. What three characteristics determine the type of sedimentary rock?
Answer:
Characteristics of Sedimentary Rocks. ● The color of the sedimentary rock is determined by the content of the strata that were pressed together to form it. If the layers have a high organic content, the rock is usually gray to black in color. On the other hand, high amount of minerals give the rock the color of the mineral.

uses of indicators in points?
Answer:
The common application of indicators is the detection of end points of titrations. The colour of an indicator alters when the acidity or the oxidizing strength of the solution, or the concentration of a certain chemical species, reaches a critical range of values.
25cm3 of a 0.4M sodium hydroxide solution was diluted into 250cm3 of water. What is the molarityof the resultant solution.
Answer:
0.04 M
Explanation:
From the question given above, the following data were obtained:
Initial volume of solution (V1) = 25 cm³
Initial Molarity of solution (M1) = 0.4 M
Final volume of solution (V2) = 250 cm³
Final Molarity of solution (M2) =?
We can obtain the final Molarity of the solution by using the dilution formula as illustrated below:
M1V1 = M2V2
0.4 × 25 = M2 × 250
10 = M2 × 250
Divide both side by 250
M2 = 10/250
M2 = 0.04 M
Therefore, the resulting molarity of the diluted solution is 0.04 M

A clear, pure liquid sample is brought into the lab and exposed to an electrical current. Different gases are
produced on each of the electrodes. The sample is -
a. an element
b. an alloy
c. a compound
d. a polymer
The sample here is a compound. The correct option is c.
What is a compound?A chemical compound is a substance made up of many identical molecules that contain atoms from more than one chemical element and are held together by chemical bonds.
A molecule made up of only one element's atoms is thus not a compound.
The anode undergoes oxidation, while the cathode undergoes reduction. The species being oxidized provides the electrons.
An electrode in an electrochemical cell is referred to as an anode or a cathode depending on the direction of electron flow.
The electrode reacts with the electrolyte at the anode, producing electrons.
These electrons build up at the anode. Meanwhile, another chemical reaction occurs at the cathode, allowing that electrode to accept electrons.
Thus, the correct option is c.

HELPP ILL GIVE BRAINLIEST
Answer: its b
Explanation:
What is the molecule that formed between B and F?
Answer:
BF3
Explanation:
For this question, you need to use the number of valence electrons present in each element. Boron is in group 3/13 on the periodic table so you know it has 3 valence electrons while Fluorine is in group 7/17 so it has 7 valence electrons. These elements are both covalent so they will share electrons. All elements in the first three rows want to reach either have 8 valence electrons or zero valence electrons depending on whichever is easier. When B and F interact each Fluorine will only want to take one electron, but Boron wants to get rid of all 3 electrons, so it will bond with 3 Fluorine to get rid of all its valence electrons.

How many moles of oxygen are required to produce 37.15 g CO2? 37.15 g CO2 = mol O2
Answer:
0.84 moles of oxygen are required.
Explanation:
Given data:
Mass of CO₂ produced = 37.15 g
Number of moles of oxygen = ?
Solution:
Chemical equation:
C + O₂ → CO₂
Number of moles of CO₂:
Number of moles = mass/molar mass
Number of moles = 37.15 g/ 44 g/mol
Number of moles = 0.84 mol
Now we will compare the moles of oxygen and carbon dioxide.
CO₂ : O₂
1 : 1
0.84 : 0.84
0.84 moles of oxygen are required.

What element is represented by the ground state electron configuration shown above?
Answer:
Pd (palladium).
Explanation:
46 electrons total, this is representative of the Pd (palladium) element.
Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Palladium (Pd) element is represented by the ground state electronic configuration.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.
The ground state electronic configuration of 1s² 2s² 2p⁶3s² 3p⁶4s² 3d¹⁰ 4p⁶ 5s² 4d⁸ shows total 46 electrons. The element with atomic number 46 is palladium, Pd. Palladium is a d block element. Palladium is found in group 8 and period four of periodic table.

List all the layers of the atmosphere and give one SENTENCE description or characteristic for each layers.
Answer:
Troposphere, stratosphere, mesosphere, and thermosphere.
Explanation:
Troposphere - It is the lowest region of the atmosphere, extending from the earth's surface to a height of about 3.7–6.2 miles (6–10 km), which is the lower boundary of the stratosphere.
Stratosphere - It is the layer of the earth's atmosphere above the troposphere, extending to about 32 miles (50 km) above the earth's surface (the lower boundary of the mesosphere).
Mesosphere - It is the region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles (50 and 80 km) in altitude.
Thermosphere - It is the region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium. The thermosphere is characterized throughout by an increase in temperature with height.
Answer:
The First layer is the troposphere. The troposphere is what we live in. It creates weather for us. Second layer is the Stratosphere. You will find the ozone layer in it. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. Life as we know it wouldn't be possible without this layer of protection. Third layer is Mesosphere. The Mesosphere is very important for earth's protection. The mesosphere burns up most meteors and asteroids before they are able to reach the earth's surface. Fourth layer is Thermosphere. The Thermosphere absorbs the sun radiation making it very hot.
Explanation:: I don't know if you include this one but the fifth layer is the Exosphere. Although the exosphere is the most distance layer of earth's atmosphere it is the layer that is the planet's first line of defense against the sun's rays. It is also the first layer to come into contact and protect the earth from meteors, asteroids, and cosmic rays.
