Most air masses form over cold areas called polar regions or warm tropical areas.
In addition, they will form over oceans and be moist. Air masses that form over the ocean are called maritime and they form over continents. Air masses that form over continents are dry and are called continental air masses.
Remember air masses take on the conditions of where they are formed.
Let’s take a look at all of the air masses the Earth has
Maritime tropical are warm and moist
Maritime equatorial are hot and moist
Maritime polar cold and moist
Continental tropical warm and dry
Continental polar cold and dry
Continental arctic and Antarctica very cold and dry

This video is about the Law of Superposition and includes a demo to help with understanding.
The law of superposition is that the youngest rock is always on top and the oldest rock is always on the bottom. so the relative ages came to be arranged by the depth of the rocks.

The tropical rainforest is located around the equator and is hot, humid, and receives much rainfall.

Types of Animal Movement
In this video I show some of the different ways animal move. Some animals move on 4 legs, others on 2. Some animals move by oozing along, while others swim.
Enjoy this video on animal movement.

Learn why we have sea and land breezes. Almost anytime you go to the beach you will encounter some wind. This is because of the land and water heating up and cooling off at different rates.
Land warms up and cools off more quickly than water. Warm air creates a low-pressure area and cold air creates a high-pressure area. Air will always flow from high pressure to low pressure and this will generate wind.

Rocks are all around us. They make up the crust of the Earth and are found on the surface of the Earth.
Rocks can be classified according to how they are formed.
Igneous rocks are formed from rock that has melted
Sedimentary rocks form from deposits
Metamorphic rocks form from other rocks when exposed to heat and pressure

Skip ahead to the specific rock type

3:16 Sedimentary Rocks
5:39 Metamorphic Rocks

Learn about the four Spheres of the earth.
The earth can be divided into four major spheres.
The biosphere which means life.
The hydrosphere which makes up all the water of the earth
The atmosphere which is the air of the earth
The geosphere which is all of the rocks, soil, and layers of the earth.

These four spheres of the earth allow life to exist on planet earth

Selective breeding (also called artificial selection) is when humans use animal breeding and plant breeding to develop offspring with traits they desire.
Selected breeding has been practiced for years with plants and animals.
Selective breeding has been used with horses, dogs, rice, wheat and corn

Let’s look at some examples,
Look at these two dogs
This Chihuahua mix and Great Dane shows the wide range of dog breed sizes created using selective breeding

Transverse waves are waves in which the oscillation is at a right angle to the direction of the wave.
A transverse wave has a crest, trough, wavelength, resting point, wavelength, and frequency.

The Law of Conversation of Mass states that the mass of the reactants must equal the mass of the products in all chemical reactions.
I use a simple demonstration to show this point. I use baking soda and vinegar which is a simple chemical reaction, to demonstrate the law of conservation.
Correction:
0:41 I accidentally said grams instead of ounces while weighing the materials. My mistake.

Matter is most often found as either a solid,liquid or a gas. Matter can also move from one phase to another when heat or energy is added or subtracted. In this video, I illustrate this with a triangle that show how matter moves from one state to another.

Igneous Rocks are created from molten rock that is either on the surface (lava) or inside the Earth ( magma)

Excretory system
The excretory system removes waste and toxins from the human body.
Your skin eliminates waste by sweating.
Your lungs eliminate carbon dioxide.
Your kidneys filter over 180 liters of blood in order to produce urine.
The kidneys filter waste like urea. This liquid that is collected is called urine.
Your kidneys are made up of millions of filtering units called nephrons.

10 Mutualism Examples

Mutualism is a symbiotic relationship in which both organisms involved in the relationship benefits from the relationship.

Many times mass and weight are used to describe the same thing. However, these two measurements are different. In this video, I explain the difference between mass and weight.
Mass is a measure of how much matter something contains, which equals the number of atoms in it
Weight is a measure of how strongly gravity pulls on something

The SI unit for mass is kilograms
The SI unit for weight is the newton N

Sedimentary Rocks are rocks formed from rock fragments and organic matter.

Sedimentary rocks are formed from pre-existing rocks or pieces of once-living organisms. They form from deposits that accumulate on the Earth's surface or under the ocean. The particles that form a sedimentary rock are called sediment and may be composed of minerals or organic matter.
The following rocks are sedimentary Rocks
Shale, Conglomerate, Limestone, Sandstone
