Healthy Screen Time Tips and Plate Tectonics

Healthy Screen Time Tips

• Sit properly with back supported by the chair backrest
• Change positions regularly to avoid strain
• Keep dim lighting in the room to avoid eye damage
• Stretch during commercial breaks to move around and relax
• Avoid watching TV in bed to prevent neck and back ache

Plate Tectonics

• Plate tectonics explains the features and movement of the Earth's surface
• The Earth's surface is broken into numerous segments called plates
• There are 7 large plates: African, Antarctic, North American, South American, Indian, Australian, and Pacific plates
• Plate movements can result in earthquakes, volcanism, and mountain formations

Earth's Structure

• The Earth's mantle is a 100 km thick layer of solid rock
• The lithosphere is the outermost solid layer of the Earth, including the crust
• The asthenosphere is the softer, solid layer beneath the lithosphere
• Convection in the asthenosphere forms the foundation of plate tectonics

Distribution of Earthquakes, Volcanoes, and Mountain Ranges

• Earthquakes are not randomly distributed, but tend to be concentrated in narrow zones
• Volcanoes are not randomly distributed, but are found along the edges of some continents
• Mountain ranges are formed by plate movements, resulting in earthquakes and volcanism
• The Philippines is situated in the Ring of Fire, a geologically active area with frequent earthquakes and volcanic eruptions

The Ring of Fire

• The Ring of Fire is a long chain of volcanoes and tectonically active structures surrounding the Pacific Ocean
• It is also known as the circum-Pacific belt
• About 90% of the world's earthquakes occur in the Ring of Fire
• Notable volcanoes in the Ring of Fire include Mount Pinatubo, Mount Fuji, and Mount St. Helens

Healthy Screen Time Tips

• Maintaining good posture with back support is essential for comfortable screen time
• Regularly changing positions helps prevent physical strain
• Dimly lit rooms reduce eye damage risk
• Taking stretching breaks during commercials promotes movement and relaxation
• Avoiding TV time in bed prevents neck and back aches

Plate Tectonics

• Plate tectonics is a theory explaining Earth's surface features and movements
• Earth's surface is composed of numerous segments called plates
• There are 7 large plates: African, Antarctic, North American, South American, Indian, Australian, and Pacific
• Plate movements cause earthquakes, volcanic activity, and mountain formations

• Convection in the asthenosphere drives plate tectonics

Distribution of Earthquakes, Volcanoes, and Mountain Ranges

• Earthquakes occur in concentrated zones, not randomly distributed
• Volcanoes are not randomly distributed, but are found along some continents' edges
• Mountain ranges form due to plate movements, resulting in earthquakes and volcanic activity
• The Philippines is situated in the Ring of Fire, a geologically active area with frequent earthquakes and volcanic eruptions

The Ring of Fire

• The Ring of Fire is a long chain of volcanoes and tectonically active structures surrounding the Pacific Ocean
• It is also known as the circum-Pacific belt
• Approximately 90% of the world's earthquakes occur in the Ring of Fire
• Notable Ring of Fire volcanoes include Mount Pinatubo, Mount Fuji, and Mount St. Helens
