Describe the changes on the Earth’s surface as a result of earthquakes and volcanic eruptions


NOTES ON EARTH'S SURFACE, VOLCANIC ERUPTIONS, EARTHQUAKE

MECL CODE: S6ESIVa-1
QUARTER 4, WEEK 1

Changes on Earth's surface caused by earthquakes:


Earthquakes are caused by the movement of tectonic plates beneath the Earth's surface.
When tectonic plates move, they can create seismic waves that can cause the ground to shake and buildings to collapse.
Earthquakes can cause landslides, tsunamis, and the formation of new cracks or fissures in the ground.
Earthquakes can also cause the ground to sink or rise, which can change the landscape of an area.

Changes on Earth's surface caused by volcanic eruptions:


Volcanic eruptions are caused by the movement of magma or molten rock beneath the Earth's surface.
When magma rises to the surface, it can cause a volcanic eruption, which can release ash, gases, and molten lava.
Volcanic eruptions can cause landslides, mudflows, and the destruction of buildings and homes.
Volcanic eruptions can also create new landforms, such as mountains and islands, as well as change the topography of an area.
Overall, earthquakes and volcanic eruptions can cause significant changes to the Earth's surface, and it's important to understand these natural phenomena in order to prepare for and respond to their effects.

[Q3] ENERGY TRANSFER

Image
  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 Ener...

A) Static friction B) Rolling friction C) Sliding friction D) Fluid friction   4) When an object is on a flat surface and at rest, what is the direction of the force of friction acting on it? A) Upwards B) Downwards C) Towards the surface D) Perpendicular to the surface   5) What is the relationship between friction and the motion of an object? A) Friction always causes an object to slow down B) F...

  Staying Safe: What to Do Before, During, and After Earthquake and Volcanic Eruptions By Pj Miana MELC: Enumerate what to do before, during and after earthquake and volcanic eruptions   Hello Grade 6 learners! Today, we're going to talk about something very important: staying safe during earthquakes and volcanic eruptions. These are natural events that can be scary, but with the right knowledge, we can be prepared and know what to do!   Before an Earthquake or Volcanic Eruption :   1. Prepare an Emergency Kit: Have a bag ready with essentials like water, non-perishable food, a flashlight, batteries, a first-aid kit, and important documents. Keep this kit in an easily accessible place.   2. Make a Family Plan: Talk with your family about where to meet if you get separated during an earthquake or eruption. Choose a safe spot away from buildings and trees.   3. Learn about Safe Places: Know which places in your home or school are safes...
