What is a kite in Geometry?
A kite has four sides, therefore it is a Quadrilateral
One of the first things you may notice is that there are two pairs of different-length sides.
The perimeter of a kite is found by adding the length of all four sides.
You can find the area by using the diagonals of the kite. A kite has one diagonal that is longer than the other diagonal.

Weathering breaks down the rock, and erosion carries the rock away. In this video, I explain the difference between weathering and erosion.
Weathering weakens rocks and breaks the rock down using chemical or physical changes.
The physical changes may be abrasion, wind, water, or ice.
Chemical changes include oxidation, hydrolysis, and carbonation.
Erosion moves the broken down rock away. This may include wind, water, or ice.

How clastic rocks form. Sedimentary rocks are derived from igneous, sedimentary and metamorphic rocks.
Sedimentary rocks make up around 75 percent of the rocks at the earth's surface
Let’s take a look at how clastic sedimentary rocks form. Clastic sedimentary rocks are the group of rocks most people think of when they think of sedimentary rocks. Clastic sedimentary rocks are made up of pieces of pre-existing rocks called clasts.
These sedimentary rocks follow wedcc in order to form
Weathering:
Erosion
Deposition
Compaction

Desert Biome is found on every continent. A desert is an area that receives rainfall of 10 inches or less a year.
Deserts can be very hot or very cold.
For example, the Sahara desert is the largest hot desert, and the Gobi desert in China is very large and cold most of the year.
Animals and plants in the desert must have adaptations that allow them to survive on little water.

Newton's third law of motion is all around us. In this video, I show real-world examples of the 3rd law of motion.
Why is Newton's third law of motion important?
For every action, there is an equal and opposite reaction.
For example, when you skateboard and push backward, the opposite reaction is to drive the skateboard forward.
A jet moves forward when the exhaust moves backward. Another example of an opposite reaction to a force.
Other examples include paddling a boat, jellyfish, basketball, and a trampoline.
By watching these examples it will give you a better understanding of how motion works.

Steps of cellular respiration
All organisms use respiration in order to produce energy.
In this video I review the basics of cellular respiration.
Welcome to MooMooMath
All living organisms practice cellular respiration.
This includes bacteria,fungi,plants, and animals
Why is cellular respiration important?
Because living organisms generate energy with cellular respiration
In plants and animals cellular respiration takes place at the mitochondria.

Think of the mitochondria as the power plant of the cell because the energy of the cell is generated at the mitochondria
Just like these powerplants and turbines generate power for their city.

Cells that need more energy have more mitochondria like muscles

At the mitochondria sugar combines with oxygen to produce carbon dioxide plus water and energy in the energy in the form of atp

Learn how to find the area of a square using the diagonal which creates a 45 45 90 triangle. The special rules of a 45 45 90 triangle can be used to find the side length.

Why do animals like insects, fish, zebras, and even Zooplankton migrate?
Animal migration is the periodic journey of an animal from one place to another and then back again. There are many examples of animals that migrate. Geese are one example. Geese migrate in search of favorable weather, a place to breed, and a food supply. In just 24 hours, these birds can travel 2,214 kilometers from Canada to the southern U.S. or vice versa.

In this video, I explain electric power in simple terms including watts, voltage, ampere, and coulombs.
Electric power is expressed with the letter P and equals voltage times Current and is written as
P = V x I
Voltage is measured in volts
Current is measured in amperes
A Coulomb is a measure of charge and it takes 6.24 x 10 18 electrons to equal a Coulomb

Learn how to calculate force and distance using the work formula.
You can use the work triangle in order to help you calculate either force in Newtons or distance in various units.

0:00 Introduction to the calculate work triangle
0:24 During a race a runner puts out 6000 Joules of work. If he runs a distance of 30 m, how much force did the runner put out?

01:17 John’s output of work was 16 Joules. He pushed the sled with a force of 8 Newtons. How far did he push the sled?

02:05 If it takes 500 Joules of work to move a chair 20 m, what force was needed?

03:01 What distance was your bike moved by a force of 20 N if the work was 1600 Joules?

The atmosphere can be divided into four individuals layers separated by changes in air temperature. These layers are the troposphere, stratosphere, mesosphere, and thermosphere.

Each layer is classified according to the temperature. As you gain elevation in the troposphere the temperature drops. The temperature range is from around 15 degrees celsius to negative 45 to 50 celsius at the top
The temperature of the stratosphere actually gets warmer with elevation and ranges from minus 45 to 50 degrees celsius at the bottom to 0 degrees celsius at the top.
The mesosphere is similar to the troposphere and the temperature decreases with elevation.
The temperature ranges from 0 degrees celsius to negative 90 degrees celsius at the top.
Finally, the thermosphere gets warmer with elevation. The temperature ranges from negative 90 degrees at the bottom to over 1500 degrees celsius at the very top

As you move from the troposphere to the thermosphere the atmospheric pressure decreases.
As you go up in elevation the atmospheric pressure decreases and as you down in elevation the atmospheric pressure increases.
In 2012 Felix Baumgartner completed a freefall parachute jump from the stratosphere. During this jump, he reached speeds of over 800 miles per hour and broke the sound barrier. He was able to reach speed because the atmospheric is so thin there was very little friction to slow him down.

Use this simple technique to find the lowest common denominator of any fractions. If you can create a factor tree you can easily find the common denominator

Learn the difference between a autotroph and a heterotroph. All plants and other organisms that produce their own food in an ecosystem are called autotrophs. Or self feeders
An Autotrophs is an organism that collects energy from sunlight or inorganic substances to produce food.
A Heterotroph is an organism that gets its energy requirement by consuming other organisms.
They are also called consumers
A heterotroph that eats only planed is called a herbivore
Heterotrophs that eat other heterotrophs are called carnivores. Lions,wolves
An organism that eats plants and animals are omnivores.

Properties of the igneous rock rhyolite
Light in color there it is classified as felsic

Rhyolite contains over 70% silica which gives this rock it a light color
Because the crystals are so small it is an extrusive igneous rock and cooled quickly
in rhyolite the crystals are often too small to see. This is due to the rapid cooling of the rhyolite lava
Rhyolite is produced by violent volcanic eruptions.
Density 2.4 -2.6 g/cm3
The texture of Rhyolite is fined grain and is classified as aphanitic
In summary
Igneous
Felsic
Extrusive
Fine-grained Aphanitic

Learn how to solve problems involving Boyle's law. Boyle's law states that as pressure increases then volume decreases and pressure decreases volume increases.
I use the Boyle's law formula Pressure x Volume = K
Example problem:
3.00 L of a gas is at 740.0 mmHg pressure. What is its volume at standard pressure?

A gas occupies 12.3 liters at a pressure of 40.0 mm Hg. What is the volume when the pressure is increased to 60.0 mm Hg?

I use a factor tree in order to find the cube root of 216.
This video is part of a playlist of finding the cube root of numbers 1 through 50

The key to understanding the difference between hypertonic, hypotonic, and isotonic solutions is understanding the relationship between the solute and solvent in a solution.
The solute is what is being dissolved and the solvent is what is doing the dissolving
The universal solvent is water.
As the concentration of solute increases the concentration of solvent decreases and as the solute decreases the concentration of solvent increases.
As a result, water will flow from high to low based on the concentration of the solvent.
