The Terrestrial planets are the four closest planets to the sun. The inner planets in order are Mercury, Venus, Earth, and Mars.
They are rocky planets that have few moons, no rings, and craters.
I review the characteristics of the terrestrial planets.

Learn how to create a dichotomous key. A dichotomous key is a method to identify objects like animals, rocks, trees, plants, and many other objects. In this video, I use monsters in order to show you how to create a simple dichotomous key. Dichotomous means two parts so the key uses two questions at each step. There are different types of dichotomous keys but in this video I show you how to make a simple key.

Ocean Biome Characteristics
The earth is 70% water. 97% of this water is made up of our oceans and seas.

Most of us only experience the ocean from the beach or on shore. If you go underwater and out into the ocean you discover it is teaming with life.

The ocean can be divided into 5 major oceans
The Pacific which is the largest, the Atlantic, Indian, southern, and the Arctic ocean.

The ocean is teeming with life. It includes animals as large as a 40-foot humpback whale and as small as microscopic plankton.
It includes a huge variety of plants and coral reefs that stretch for miles.
It also includes the largest mountain range called the mid ocean ridge.
The ocean impacts our weather and has been used for thousands of years as trade routes.

We play on the beaches of oceans and wonder what can be found in the Mariana trench which is 32,000 feet deep.

So there you have a very quick overview of our most diverse and largest biome-the ocean

Symmetry in animals
In this video, you will learn about two types of symmetry, radial, and bilateral symmetry.
Animals with radial symmetry are circular in shape and bilateral symmetry results in an animal with two equal sides.

Air masses are large bodies of air with similar temperature and humidity throughout.
In the video, I cover maritime and continental air masses. Maritime air masses form over the water and continental air masses form over land.
In addition, there are maritime tropical, maritime equatorial, maritime polar along with several types of continental air masses.

An introduction to three gas laws. I cover Boyle's law,charles's law, and Gay Lussac's.
For each law I cover the constant, what the law states, the formula, and the density.

00:20 Boyle's Law explanation
01:07 Charles's Law
01:53 Gay Lussac's law or pressure temperature law

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
Cementation

The Earth is 70 % water. However, only 3% of this water is freshwater. Much of this freshwater is frozen in glaciers, you will find some of the water in rivers and streams, and almost 30% of this freshwater is groundwater.
But What is groundwater? Groundwater is water that finds it way between the gaps of rocks and sediments underground.
As the water seeps into the ground it may find it’s way into an aquifer. Aquifers are underground rock layers saturated with groundwater. An aquifer is not an underground river but large porous layers of rock.

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.

Learn about an energy pyramid and how the transfer of energy is demonstrated. A trophic pyramid shows where most of the energy in an ecosystem can be found. Each level is called a trophic level and as you move up trophic levels 90% of the energy is lost.

What is Ecology the study of? Ecology is the study of how organisms interact with one another and their environment. In order to help understand what ecology is I give examples of Ecology.
These interactions can be between biotic and abiotic factors along with different levels of an organization like an organism, a community, a population or an ecosystem.

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
