__**Think About It:**__ //page E14:// __**Digging Deeper:**__ **Explain why spring tides are higher than neap tides?** Spring tides are higher than neap tides because the sun and moon are in an alignment during spring tides. the sun and moon form a 180 degree (straight line) to form spring tides. the moon was likely formed from a large object collided with Earth and shattered it. The remnants from this came together to form the moon. -**Amani A.**
 * //What happened to make the moon look the way it does?//
 * The moon looks the way it does because the moon was hit by several asteroids and comets but due to the moon being geologically interactive, the craters are preserved and still remain.**
 * //What is the origin of the moon?//
 * It is believed that millions of years ago, the earth was struck by a large object which caused several pieces of the Earth to break off and drift into space. These pieces slowly evolved into a giant satellite, forming the moon.** - Andrew Morris
 * //How does the Moon affect the Earth//
 * The moon affects the Earth in many ways. The moon causes tides on the Earth. Some of the tides are neap and spring tides. Spring tides are tides of increasing range, while neap tides are of decreased range Also tidal bulges have slowed down the Earth’s orbit?-Shayam Patel**
 * Explain how the sun and moon work together to create spring tides.**
 * Explain how the moon was most likely formed.**

1. //How did the Moon likely form?//
 * __Check Your Understanding__**: E 23
 * The Moon likely formed by an object the size of mars colliding with the Earth, making a piece fall off, that is the Moon.**

2. //Describe the relative positions of the Earth, the Moon, and the Sun for a spring tide and neap tide.// - David Meneses
 * For the spring tides the Earth, Sun, and Moon are aligned so the gravity and the tidal effects of them all come together and make bigger and taller tides. For the neap tides it’s the complete opposite. The Earth, the Moon, and the Sun align in a right angle so their tidal effects counteract one another causing the tides to be smaller and lower.**

3. What effect have tides had on the length of a day? Explan. -Allyson Fancher
 * __Check Your Understanding (continued):__** E 23
 * Because there are two high tides each day, each high tide is about 25 minutes later than the previous one. By the time the Earth has completed one roation, the moon is in a slightly different place because it has traveled 1/30 way in its orbit in that 24 hour period. That is why the moon rises and sets about 50 minutes later each day.**

__**Digging Deeper**__ The moon's energy is more focused on the Earth during spring tides, and less focused on the Earth during neap tides.- Kira Turner
 * 1. Explain why 'spring' tides are higher than 'neap' tides?**

5.Explain how the moon was most likely formed.
 * Scientist theorized that an object the size of Mars collided with and probably shattered the early earth. The remnants of this titanic collision formed a ring of debris around what was left of our planet. Eventually this material accreted into a giant satellite which became the moon.** - Kori S

__Formation of the Earth__: Small fragments of rocky material stuck together in a process called accretion(the process whereby dust and gas accumulated into larger bodies like starts and planets). Larger and larger pieces then came together to form the terrestrial planets. The leftovers became the raw materials for asteroids and comets. Collisions between the planets and the leftover planetesimals were common. -Carter Gentry

__Creation of the Moon:__ Scientists theorize that an object the size of Mars collided with and probably shattered the early Earth. The remnants of this titanic collision formed a ring of debris around what was left of our planet. Eventually this material accreted into a giant satellite, which became.... the.... bum bum bum... MOON! -Sean #swag

The Earth is geologically an active place therefore few craters remain on the surface, computer simulations help us to accurately predict the orbit and composition of both the Earth and moon. Earth's surface is evolving, the moon is geologically inactive. The earth's rockmarked face has preserved its early history of collisions. The Effects of Earth Rotation- When the earth first formed its day probably lasted only about six hours. Days on earth have gotten longer because the earth takes longer to make one full rotation on its axis. -Kayleah Beltran

__**TIDES**__

There are two types of tides. There are neap tides, and there are spring tides. Tides are caused by the gravitational pull of the Sun, and the moon. Neap tides are caused by the Sun, Earth, and moon forming a right angel in which both gravitational forces cancel each other out. and produce a low tide. When the Earth, Sun, and moon are in a straight line. The gravitational forces help each other and produce a spring tide (high tide). - Josh Branker

2a. Every 10 million years us 1.2 and every million is .12. 2b. Every year, it decreases by .00012. 2c. I think the earth's rotation on its axis is slowing down. The days are getting shorter and to test it, you can use a stop watch from when the sun rises to when it sets. - Carlos Davila

__**pg E 16 Part C: Tides and Lunar phases #3**__ a) High tides and phases of the moon are related because the moon’s gravity pulls on the water on earth causing high tides. b) Low tides and phases of the moon are related because the moon’s gravity pulls on the earth’s water when it is on the other side of the earth pulling it in. c) The moon affects tides because of its gravity. – **Angelo Nuni**

During a spring tide, the earth, moon and sun are in general allignment.During the neap tides the earth, moon and sun form right angles.-Arisa Higa Spring tides happen when the sun and moon are in general alignment and by the tidal pull of the sun and the moon. -Alianna Lewis

 * 2. The time that it takes for the earth to __revolve__ around the sun has not changes.**
 * 3. Earth's rotation is slowing down due to the gravitational forces between the Earth, Moon and Sun.**
