Crust-In geology, the crust is the outermost solid shell of a rocky planet.
Mantle-A mantle is a layer inside a planetary body bounded below by a core and above by a crust.
Core-is the innermost part of the earth, comprised of the inner core, at the center of the earth, made of iron; and b) the outer core, which surrounds the inner core, made of iron and magma.
Lithosphere-rigid, rocky outer layer of the Earth, consisting of the crust and the solid outermost layer of the upper mantle.
Athenosphere-the upper layer of the earth's mantle, below the lithosphere, in which there is relatively low resistance to plastic flow and convection is thought to occur.
Mesosphere-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.
Sea floor spreading-the formation of new areas of oceanic crust, which occurs through the upwelling of magma at midocean ridges and its subsequent outward movement on either side.
Plate Tectonics- a theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle.
Tectonic plates- A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. ... By contrast, oceanic crust is composed of basaltic rocks, which are much denser and heavier.
Convergent boundary- A convergent boundary is an area on Earth where two or more lithospheric plates collide. One plate eventually slides beneath the other causing a process known as subduction.
Divergent boundary- In plate tectonics, a divergent boundary or divergent plate boundary is a linear feature that exists between two tectonic plates that are moving away from each other.
Transform boundary- A transform fault or transform boundary is a fault along a plate boundary where the motion is predominantly horizontal.
Radioactive decay- a radioactive process in which a nucleus undergoes spontaneous transformation into one or more different nuclei and simultaneously emits radiation, loses electrons, or undergoes fission.
Subduction zone- Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle.
Continental drift- Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed.
Deformation- the action or process of changing in shape or distorting, especially through the application of pressure.
Folding- A fold is a bend in the rock strata. Folding: Is a type of earth movement resulting from the horizontal compression of rock layers by internal forces of the earth along plate boundaries.
Fault- A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. ... Earth scientists use the angle of the fault with respect to the surface (known as the dip) and the direction of slip along the fault to classify faults.
Shear stress- Shear stress is the stress component parallel to a given surface, such as a fault plane, that results from forces applied parallel to the surface or from remote forces transmitted through the surrounding rock.
Tension- in physics, tension is described as the pulling force transmitted axially by the means of a string, a cable, chain, or similar one-dimensional continuous object, or by each end of a rod, truss member
Compression- Compression, decrease in volume of any object or substance resulting from applied stress. Compression may be undergone by solids, liquids, and gases and by living systems.
Syncline- a trough or fold of stratified rock in which the strata slope upward from the axis.
Anticlines- an arch of stratified rock in which the layers bend downward in opposite directions from the crest.
Law of Universal Gravitation- Newton's law of universal gravitation is usually stated as that every particle attracts every other particle in the universe with a force that is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
Law of superposition- Law of superposition, a major principle of stratigraphy stating that within a sequence of layers of sedimentary rock, the oldest layer is at the base and that the layers are progressively younger with ascending order in the sequence.
law of conservation of mass- The law of conservation of mass or principle of mass conservation states that for any system closed to all transfers of matter and energy, the mass of the system must remain constant over time, as the system's mass cannot change, so quantity can neither be added nor be removed.

What is an ionic compound? Describe and give an example.
Answer:
Ionic compounds are compounds made up of ions. These ions are atoms that gain or lose electrons, giving them a net positive or negative charge. Metals tend to lose electrons, so they become cations and have a net positive charge. Ions of opposite charge are held together by very strong ionic bonds within the compound.

How many number of oxygen molecules are required to produce 0.22 g of CO2 according to the reaction?
c+o2=co2
In the following reaction, how many grams of H2O are produced if 2.00 g of N2H4 react? N2H4 + 3 O2 ---> 2NO2 + 2H2O
Answer:
2
Explanation:
From this equation, 2 grams are produced.
The mass of H₂O produced from the reaction is 2.25 g
We'll begin by calculating the mass of N₂H₄ that reacted and the mass of H₂O produced from the balanced equation.
N₂H₄ + 3O₂ —> 2NO₂ + 2H₂O
Molar mass of N₂H₄ = (2×14) +(4×1) = 32 g/mol
Mass of N₂H₄ from the balanced equation = 1 × 32 = 32 g
Molar mass of H₂O = (2×1) + 16 = 18 g/mol
Mass of H₂O from the balanced equation = 2 × 18 = 36 g
SUMMARY
From the balanced equation above,
32 g of N₂H₄ reacted to produce 36 g of H₂O.
Finally, we shall determine the mass of H₂O produced by the reaction of 2 g of N₂H₄From the balanced equation above,
, 32 g of N₂H₄ reacted to produce 36 g of H₂O.
Therefore,
2 g of N₂H₄ will react to produce = (2 × 36) / 32 = 2.25 g of H₂O
Thus, the mass of H₂O produced from the reaction is 2.25 g

are juices.
3 marks)
A) Represent the types of fruit in bar graph.
B) Represent the sales in pie graph.
Answer:
A) Please see the required bar graph attached
B) Please see the required pie graph attached
Explanation:
The given data are;
The number of each fruit in each box are;
First box contains 10 mangoes
Second box contains 7 avocados
Third box contains 5 lemons
The percentage of the things they sell are;
Organic food = 20%
Inorganic food = 50%
Juices = 30%
A) The bar graph is plotted with Microsoft Excel
The height of each column is equivalent to the number of fruit in the box
Each column represents a box of fruit
B) The pie graph (chart) is generated with Microsoft Excel
The steps to draw the pie chare are;
1) Draw a circle
2) Partition the circle into segments proportional to each percentage from the center of the circle as follows;
The sum of angles at the center of the circle = 360°
The angle of the segment that will represent the 20% organic food in the pie chart = 20/100 × 360° = 72°
Therefore, the segment representing organic food will have an angle of 72° at the center of the circle
Similarly, the segment representing inorganic food will have an angle of 50/100 × 360° = 180° at the center of the circle
The segment representing juices will have an angle of 30/100 × 360° = 108° at the center of the circle.

Answer if you know, if you don't move on please! If you don't know comment not answer. Thank you!!
Answer:
The speed of light becomes slower in denser medium which is water in this case.
Explanation:
We know the lens law of Refraction which states
[tex]\frac{Sin(i)}{Sin(r)} =[/tex] Refractive index of second medium /Refractive index of the first medium
= Velocity of light in medium 1 (V1)/ velocity of light in medium 2 (V2)
When light rays fall from air medium into water which is a denser medium bending of light or change in the direction of light occurs which is knows as Refraction.
When refraction occurs speed of the light rays are also varied as we can see it from the Lenz's Law. suppose two light rays parallel to each other falling on the air-water interface at an angle , the first ray will reach the interface and bend about the normal and then the second ray. We also observe when light enters denser medium the speed of light becomes slower, also the bending of light when going from rarer to denser it bends towards normal of the surface and when it move from denser to rarer medium it moves away from the normal to the surface.

The compound whose molecules have the highest average kinetic energy is?
Answer:
C)
Explanation:
The warmer the molecules, the higher the average kinetic energy.
"As stated in the kinetic-molecular theory, the temperature of a substance is related to the average kinetic energy of the particles of that substance. When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles. This is registered as an increase in the temperature of the substance." -lumen learning
