GEOLOGY: COORDINATE SYSTEM


 GEOLOGY: COORDINATE SYSTEM

S7ESIVa-1 | Demonstrate how places on Earth may be located using a coordinate system

A coordinate system is a system of lines or grids used to determine the position of a point on a map or a globe.

The Earth is divided into imaginary lines called latitude and longitude. Latitude lines run horizontally, while longitude lines run vertically.

Latitude lines are measured in degrees north or south of the equator, which is the imaginary line that circles the Earth at 0 degrees latitude.

Longitude lines are measured in degrees east or west of the Prime Meridian, which is the imaginary line that runs from the North Pole to the South Pole at 0 degrees longitude.

The intersection of a latitude line and a longitude line is called a coordinate or a grid reference.

Coordinates are written in pairs, with latitude first, followed by longitude. For example, the coordinates for New York City are 40.7128° N, 74.0060° W.

GPS (Global Positioning System) uses satellites to determine the coordinates of a location on Earth. This technology is widely used in navigation systems and mapping applications.

Understanding coordinates and the coordinate system is important for reading maps, navigation, and understanding the geography of different regions on Earth.

Remember, practice makes perfect. So, make sure to practice locating different places on maps and understanding their coordinates.

  Exploring the Transformation of Energy: Sound, Heat, Light, and Electricity By: Pj Miana   Introduction: Energy is all around us, and it can take many forms. In this lesson, we'll delve into how different types of energy—sound, heat, light, and electricity—can be transformed from one form to another. Understanding these transformations helps us comprehend the world and the technology we use every day.   1. Sound Energy: Sound energy is produced by vibrations traveling through a medium, such as air, water, or solids. It can be transformed in various ways:   - Mechanical to Sound : When an object vibrates, it creates sound waves. For example, when you pluck a guitar string, the mechanical energy of your hand's motion is transformed into sound energy.   - Sound to Electrical : Microphones transform sound waves into electrical signals. These signals can then be amplified and converted back into sound through speakers.   2. Heat Energy: Heat energy is

SEPARATING MIXTURES BY: PJ MIANA Introduction Understanding and mastering techniques for separating mixtures is not only a fascinating aspect of science but also an essential life skill. In our daily lives, we encounter a multitude of mixtures, from the ingredients in our kitchen to environmental challenges such as pollution and water purification. Learning how to effectively separate mixtures is crucial for solving real-world problems, making informed decisions, and gaining a deeper understanding of the world around us. In this lesson, we will explore various techniques such as picking, winnowing, decantation, the use of magnets, sieving, filtering, and evaporation. These techniques are not only fundamental to scientific inquiry but also find practical applications in industries like agriculture, food processing, environmental science, and more. By grasping these methods, we empower ourselves to tackle complex challenges, conserve resources, and contribute to a cleaner and more sustai
