Meteoroids and Meteorites Overview

Meteoroids, Meteors, and Meteorites

• Meteoroids are small, rocky or metallic bodies orbiting the Sun.
• When a meteoroid enters Earth's atmosphere, it burns up, producing a streak of light called a meteor.
• Meteorites are meteoroids that survive atmospheric entry and impact the Earth's surface.

Asteroid Impact Events

• Asteroids are large, rocky bodies orbiting the Sun.
• Asteroid impacts can cause significant damage and even mass extinctions.
• The frequency and potential impact of asteroid collisions are a concern for scientists.

Meteor Formation

• Meteor formation occurs when a meteoroid enters Earth's atmosphere.
• Friction with the air causes the meteoroid to heat up and vaporize.
• The resulting bright streak of light is a meteor.

Meteorite Classification

• Meteorites are classified based on their composition (iron, stony, stony-iron).
• Iron meteorites are primarily composed of iron and nickel.
• Stony meteorites are composed of silicate minerals.
• Stony-iron meteorites contain a mixture of both iron and silicate minerals.

Earthquake Mechanics

• Earthquakes are sudden releases of energy in the Earth's lithosphere.
• These releases cause seismic waves that travel through the Earth.
• Faults are fractures in the Earth's crust where rocks slip past each other.
• Plate tectonics is the theory explaining the movement of Earth's lithospheric plates.

Tsunami Generation

• Tsunamis are large waves generated by disturbances in the ocean, such as earthquakes, volcanic eruptions, or landslides.
• Earthquakes along the ocean floor can displace large volumes of water, creating tsunamis.
• Tsunami wave height can vary significantly, depending on the distance from the source and the depth of the ocean.

Typhoon

• Typhoons are intense tropical cyclones.
• They form over warm ocean water and are characterized by strong winds and heavy rainfall.
• Typhoons can cause significant damage to coastal areas.
