Geological Processes & Landforms

Geological Processes

Geological Processes is Part 3 of The Earth - a Junior Science Title. With this title, you'll survey the geologic timescale, examine the theory of plate tectonics, and understand the processes by which rocks are formed.

Exploring Landforms 

Landforms are natural features of the earth's surface. Landforms are all around us! Mountains, valleys, oceans, rivers, cliffs, beaches, caves, volcanoes - they are all landforms

The Rock Cycle 

There are many types rock on the earth like igneous, sedimentary etc. but do you think why are they are named so or how they are made?

In this video, you will learn about complete rock cycle as how they changed with time and how they converted from one form to another.

MOUNTAIN RANGES & CONTINENTAL DRIFT

How plate tectonics shapes our planet

Mr. Andersen describes how plate tectonics shapes our planet. Continental and oceanic platers are contrasted and major plate boundaries are discussed.

Continental Drift

A brief overview of the theory of continental drift and the evidence supporting it. This video explores how the apparent fit of the continents, fossil and rock correlation, and paleoclimate data support Alfred Wegener's ground-breaking theory.

HEAT & TEMPERATURE

1.-Difference between Heat and Temperature

2.-Thermal Energy vs Temperature

Which has more energy – an ice berg or a cup of coffee?

3.-Heat Transfer

Heat is the transfer of energy from objects of different temperatures. As objects warm-up or cool down their kinetic energy changes. Kinetic energy is the energy of motion

Interactions between species

Interspecific and intraspecific relationships

From this video you should know the difference between interspecific and intraspecific, and that interactions can be positive, negative or neutral.

Community Ecology

Interactions between species are what define ecological communities, and community ecology studies these interactions anywhere they take place. Although interspecies interactions are mostly competitive, competition is pretty dangerous, so a lot of interactions are actually about side-stepping direct competition and instead finding ways to divvy up resources to let species get along

WHAT IS ENERGY?

We need and use energy in all activities. Energy is the capacity to do work. This educational video is designed to explain what is energy, sources of energy, and uses of energy. We see the various applications of energy through an example of a family picnic, and see various types of energy in action. This video teaches all aspects of energy in an engaging and clear manner.

This video provides you a greater understanding about what energy is.

CHARACTERISTICS OF BIRDS

CHARACTERISTICS OF BIRDS

1.-Did you now that the fastest bird is the peregrine hawk? This bird of prey can reach up to 400 kilometers per hour whist free falling. Wow it’s so fast, poor dove if it were to cross its path…

2.-Twelve characteristics that most birds share but that most other animals do not.

HABITAT & NICHE

Difference between habitat and niche - ecology

Learn how the habitat and niche are different but also very important for a healthy environment.

A habitat is an ecological area where a plant or animal lives. It may be an island, a tree, or maybe under a rock. The habitat is where an individual can find food, shelter, protection and mates.

A niche is a role or position that an individual has in its environment. A niche may also involve what the individual eats, how it interacts with other living things, and also how it interacts with the nonliving factors. Without ecological niches, there would be less biodiversity, and the ecosystem would not be in balance.

SMELL & TASTE

Smell and Taste

Hank resists the urge to devour a slice of pizza so that he can walk you through the way we experience our major special senses.

SIMPLE MACHINES

This is an interesting compilation of simple machines. These simple machines use the fundamental law of forces and mechanics to carry out very simple movements. These in turn can be used to create machines that we see around us in our everyday lives. Pulley is a simple machine and comprises of a wheel on a fixed axle, with a groove along the edges to guide a rope or cable. The lever is one of the most basic forms of a machine. They help us lift loads with lesser effort. Even though this looks simple there are many things going on in order to lift the object easily. An inclined plane is a ramp that assists moving heavy objects up and down heights. It is a plane surface set at an angle, other than a right angle, against a horizontal surface. A screw is one of the most commonly used mechanical devices in the world. It is machine that converts rotational motion into linear motion. The wedge is the active twin of the inclined plane and one of the six classical simple machines. Unlike an inclined plane, which is stationary, a wedge does useful work by moving.

INVASIVE SPECIES

The basics
What are Invasive Species? An invasive species is one that is not native and whose introduction causes harm, or is likely to cause harm to Michigan's economy, environment, or human health.

The threat of invasive species.
An invasive species can be anything from plant, animal or fungus that is introduced to a non-native habitat and has a tendency to spread to a degree that causes damage throughout the environment, human health or economy.

Today we’re going to look at vertebrate animals. As you know, we can classify animals in various ways, depending on the characteristics we look at.

What is an ecosytem?

In this video you'll learn all about ecosystems and how energy is transferred between organisms living together it the same environment.
