Just as cells are basic to biologists, and periods/eras are essential to historians, regions are basic to geographers. It gives them a way of differentiating different areas of the world to aid their analysis. Geographers also need to choose how to define those regions. A Formal Region is just one way of doing it. It …
DEFINITION: Compound machines are complex systems made of multiple simple machines working together to perform tasks. They leverage the combined mechanical advantages of various components to accomplish specific functions or actions. EXPLANATION: Machines can be either simple or compound. Simple Machines Simple machines are machines in their simplest forms. They work through the application of …
We come across intersecting lines every day. However, if you take a closer look at two intersecting straight lines, you will notice something interesting: four angles are formed when two straight lines intersect. You will also notice that the two opposite angles are equal. The two intersecting lines form two pairs of vertical angles. Vertical …
Angles are those spaces formed between two intersecting lines. They are measured in degrees. Angles make up part of many structures and shapes in the world around us. Supplementary angles in geometry are angles whose sum is 180 degrees. These angles, therefore, form a straight line when joined together. However, they do not have to …
DEFINITION: Contact forces are interactions between objects in direct physical contact, generating forces through direct touch or contact. EXPLANATION: When it comes to forces, you can pick from two flavors: contact forces or non-contact forces. All forces either belong to one or the other. By their names, we already have a clue of what they …
DEFINITION: A suspension mixture is a heterogeneous combination where particles of a substance are dispersed but not dissolved in another medium, remaining suspended due to gravity and requiring agitation for stability. EXPLANATION: There’s nothing better than a hot cup of chocolate on a cold day to warm the body up. If you want to make …
We come across pentagons every day. Take a close look at a house. The outline of the house when viewed from the side has five sides and five angles. This makes it a pentagon. Pentagons are shapes with five angles and five straight sides. Penta is a prefix that means five. Gon is a suffix …
Whenever you enjoy that coveted cup of tea, you should thank the process of sedimentation for the pleasure. The swirling of tea leaves which finally settle down to the bottom of the cup gives you that special flavor. While this may be a minor event like a storm in a teacup, the same process also …
DEFINITION: A colloid mixture consists of small particles dispersed in another substance, creating a homogeneous yet not fully dissolved solution. It exhibits intermediate particle size between solutions and suspensions. EXPLANATION: You’re probably familiar with a variety of mixtures such as suspensions and solutions. Colloid mixtures are one of the primary types of mixtures. They are …
Angles are everywhere around us. They form part of the basic structure of many of the shapes that we encounter in our daily lives. Adjacent angles are angles that share a common vertex and arm or side and do not overlap. They instead lie on opposite sides of the arm they share. When two non-common …
