Asteroids are rocky objects traveling through space or orbiting stars or planets.
Meteorites are asteroids that collide with planets or satellites.

The Solar System

The Sun is medium in size.

The Layers of the Earth

The Earth is a rocky, spherical body, slightly flat at the poles.
It has three main parts: the atmosphere, the hydrosphere, and the geosphere.
The atmosphere is the layer of air surrounding the Earth.
The hydrosphere encompasses all the water on Earth, covering approximately 70% of the surface.
The geosphere is the solid, rocky part of the Earth, composed of three layers:
- The crust forms the continents and seabed.
- The mantle lies between the crust and core, composed of very hot rocks.
- The core is the center of the Earth, made up of metal.

It rotates on its axis while revolving around the Earth, taking 29 and a half days for a full rotation.
The Moon is rocky and spherical, lacking an atmosphere or hydrosphere.
Craters on the Moon are formed by meteorite collisions.
The Moon does not produce light; it reflects light from the Sun.
The phases of the Moon refer to how we see it from Earth, appearing larger or smaller depending on its position.
Tides are the rise and fall of sea level, caused by the Moon's gravitational pull on Earth's water.

Solar Eclipses

A solar eclipse occurs when the Moon moves between the Sun and the Earth, blocking part of the Sun's light and causing the sky to darken.

How the Earth Moves

The Earth revolves around the Sun, taking 365 days and 6 hours for one complete revolution, which is one year.
The Earth rotates on its axis, completing one rotation in 24 hours, which is one day.
The Earth's rotation causes day and night.

The Seasons in the Northern Hemisphere

The Sun's rays strike the Northern Hemisphere at different angles throughout the year due to the Earth's position during its revolution.
The difference in angle causes changes in temperature and daylight hours, resulting in the four seasons:
- Summer: June 21st - September 23rd, longer days and hotter temperatures.
- Autumn: September 23rd - December 21st, same length days and nights, and mild temperatures.
- Winter: December 21st - March 20th, longer nights and colder temperatures.
- Spring: March 20th - June 21st, same length days and nights, and mild temperatures.
