__Check your understanding #3__. What effect have tides had on the length of a day? tides have a somewhat small effect on the length of the day.The tides bulge towards and away from the moon as it passes by. Due to this tides form a cycle in which the rotate. Each cycle is not exactly 24 hours long. after the earth has completed one rotation, the moon is in a different place because it has traveled about 1/30 of its way around earth. thus causing the moon to rise and set 50 min later each day.

How was the Moon formed?

Scientists say that an object(about the size of mars), collided and shattered the early Earth. The leftover pieces of this collision formed a ring of debris around the remainder of our planet. This material then formed into a giant satellite, which became the moon. The Moon is geologically inactive.

 * This picture shows the phases of the moon.**
 * A waxing moon refers to the moon growing from new to full.**
 * A waning moon refers to the moon shrinking from full to new.**
 * A gibbous moon is where you can see most of the moon but not all of it.**
 * A crescent moon is where you can see very little of the moon, but it's still visible to you.**

Spring tides are higher than neap tides because of the 180 __degree__ alignment with the moon and the sun. Spring Tide: the tides of increased range occurring semimonthly near the times of full moon and new moon. Neap Tide: the tides of decreased range occurring semimonthly near the times of the first and last quarter of the moon.
 * Explain why 'spring' tides are higher than 'neap' tides? **

Check Your Understanding. Describe the relative positions of the Earth, the Moon and the Sun for a spring tide and a neap tide.

A Neap tide occurs when the Sun and the Moon create a 90º angle with each other and the Earth is at the center. A spring tide occurs when the Sun, the Moon and the Earth create a 180º, or straight line, from each other.

**Activity 2- Digging Deeper- Formation of Earth **
====Large peices of rocky material in space came together to form the terestrial planets, and the leftovers from that became asteroids and comets. Collisions between the planets and leftover planet peices were common, and thats how the Earth was born. __Accretion__ is the small fragments of rocky materials called //planetesimals// that stuck together. ====

 * 1) 1. Scientists theorize that an object the size of Mars collided and shattered the early earth.
 * 2) 2. The remnants of the __collision__ formed a ring of debris around what was left of our planet.
 * 3) 3. This material accelerated into a giant satellite and became the moon.

Digging Deeper- Moons effects on tides
==== Bulges in oceans tides create high and low tides. Gravitational pull of the Sun also affects the tides. Spring tides increased range during a New moon and a Full moon. Neap tides occur during the First quarter and Third quarter moons. Spring tides are aligned at 180 degrees and Neap tides form a 90 degrees. ====

Why does the moon have more craters? The moon is geologically an inactive place. While earth on the other hand is geologically active earth's surface has evolved since it was created therefore leading to few remaining craters. The opposite applies for the moon the moons craters are preserved from early __collisions__ and remain due to inactiveness. By: Lea Kincaid .

The moon has eight different phases that depend on the alignment of the Earth, Moon, and the sun. The moon has a major effect on the tides of the oceans also. Scientist believe that an object the size of mars collided with the early Earth and broke off pieces and one piece got caught in the gravitational pull of the earth and that’s how the moon got there – Kory Sanders

Other than the overall look of Neap tides and Spring tides, another way to look at them is that the tidal bulges are always located on the sides of the Earth that point toward and away from the moon, while the Earth with its landmasses is rotating below the bulges. Each time it has landed on the spinning Earth encounters a tidal bulge there is a high tide at the location.

** Digging Deeper Activity 2 ** The moon and sun __work__ together to create neap tides because when the line between the earth and sun make a right angle, (90 degrees,) with the line from the earth and the moon, their tidal effects tend to counteract one another. By: Brittany Stocker
 * 3.) Explain how the sun and the moon work against each other to create neap tides.**

DD Act 2. Describe how tidal friction created by the moon acts like a brake on the earth. This friction is just a more intense gravitational pull between the earth and the moon. As the earth rotates it is slowed down by the gravity causing its rotation to slow down just like the friction of brakes and tires stop or slow down a car. Nick Mehler

Digging Deeper-Tides -Luke Bickerstaff The gravitational pull between the Earth and the moon is strong. This force actually streches the solid Earth about 20 cm along the Earth-Moon line. This stretching is called the Earth tide. The water in the oceans is streched the same way. It is a greater effect in the ocean because water flows more easily than the rock in Earths interior. These bulges in the oceans create high and low tide.

Although the sun is very far from the Earth is still has an effect on it. The sun is around 150,000,000 km away and yet the Earth is still affected by the Suns gravitational pull. This pull affects the tides but not at to such an extent as the moon. The moon creates 2.4 more time the gravitational force effecting tides than the sun does. -Tommy Rutt
 * Sun and the Moon**

Sun Affecting Gravitational Pull The gravitational pull of the Sun also affects tides. Even though it has much greater mass than the Moon, its tidal effect is not as great, because it is so much farther away from the Earth. The Moon is only 386,400 km away from the Earth, whereas the Sun is nearly 150,000,000 km away. -Gage Chumney

Special super-accurate clocks have also established that the day is gradually becoming slightly longer as well, because of this same phenomenon, called "tidal friction." The day has gradually become longer over geologic time. As the Earth system evolves, cycles change as well. -Joshua Kirtley

I thought this picture was such an inventive way to show the phases of the moon. It would make an interesting in-class project. She even drew the Sun on one edge and made a cupcake for the moon! You would probably make the cupcake frosting a different color, but that's my weird opinion. I like it though she's probably in thirs grade or something. - Elise Cortie
