Emily Atkinson

The document discusses facts about the Earth and the Moon. It begins by providing basic information about the spherical shape and rotation of the Earth, and states that the Earth's rotation causes the sun and moon to appear to move through the sky. It then provides more details about the Earth, such as that it takes 365 days to orbit the sun and is mostly covered in water. Facts about the Moon are also given, including that its name is the Moon, it has different regions like maria, and its phases are caused by its revolution around the Earth.

Watch  this  video  on  how  the  Earth,  Moon  and  Sun  all  rotate  together!   Make  FULL  SCREEN,  Click  PLAY  and  play  with  the  number  of  hours,  days  and  months   1. Can  you  make  the  Earth  orbit  just  once  around  the  Sun?  How  many  MONTHS  does  it   take?       2.

Click  on  LABELS  and  then  click  on  each  magnifying  glass  to  find  out  more  details  about   the  Earth,  Moon  and  Sun.    
    Answer  Sheet   A. Facts  about  the  Earth   1. Makes  one  complete  orbit  around  the  Sun  every  365.27  days.   2. Is  mostly  covered  by  water  (75%).   3. Has  a  total  of  1  satellite  (the  Moon).   B. Earth’s  Rotation   1. The  Earth  is  rotating  around  an  axis  (called  its  rotational  axis).   2. Some  objects  rotate  about  a  horizontal  axis,  like  a  rolling  log.  Some  objects,  such   as  a  skater,  rotate  about  a  vertical  axis.  The  Earth's  axis  is  tipped  over  about   23.5°  from  vertical   3. The  Earth  rotates  around  once  in  24  hours  -­‐  that's  a  rate  of  1000  miles  per  hour!.   The  time  it  takes  for  the  Earth  to  rotate  completely  around  once  is  what  we  call  a   day.  It's  Earth's  rotation  that  gives  us  night  and  day.   C. The  Moon  –  Facts  and  Information   1. The  Earth's  one  natural  satellite,  the  Moon,  is  more  than  one  quarter  the  size  of   Earth  itself  (3,474  km  diameter).   2. While  there  are  only  two  basic  types  of  regions  on  the  Moon's  surface,  there  are   many  interesting  surface  features  such  as  craters,  mountain  ranges,  rilles,  and   lava  plains.  The  structure  of  the  Moon's  interior  is  more  difficult  to  study.   3. The  Moon's  top  layer  is  a  rocky  solid,  perhaps  800  km  thick.   4. Beneath  this  layer  is  a  partially  molten  zone.  Although  it  is  not  known  for  certain,   many  lunar  geologists  believe  the  Moon  may  have  a  small  iron  core,  even  though   the  Moon  has  no  magnetic  field.   D. The  Phases  of  the  Moon   1. The  revolution  of  the  Moon  around  the  Earth  makes  the  Moon  appear  as  if  it  is   changing  shape  in  the  sky.    This  is  caused  by  the  different  angles  from  which  we   see  the  bright  part  of  the  Moon's  surface.    These  are  called  "phases"  of  the   Moon.     2. The  Moon  passes  through  four  major  shapes  during  a  cycle  that  repeats  itself   every  29.5  days.   3. Below are pictures of the four major shapes and a description of each. New Moon: The lighted side of the Moon faces away from the Earth. This means that the Sun, Earth, and Moon are almost in a straight line, with the Moon in between the Sun and the Earth. The Moon that we see looks very dark.
First Quarter: The right half of the Moon appears lighted and the left side of the Moon appears dark. During the time between the New Moon and the First Quarter Moon, the part of the Moon that appears lighted gets larger and larger every day, and will continue to grow until the Full Moon. Full Moon: The lighted side of the Moon faces the Earth. This means that the Earth, Sun, and Moon are nearly in a straight line, with the Earth in the middle. The Moon that we see is very bright from the sunlight reflecting off it. Last Quarter: Sometimes called Third Quarter. The left half of the Moon appears lighted, and the right side of the Moon appears dark. During the time between the Full Moon and the Last Quarter Moon, the part of the Moon that appears lighted gets smaller and smaller every day. It will continue to shrink until the New Moon, when the cycle starts all over again. 4. There are also four other phases of the Moon sometimes used. They are as follows: This is known as a Waxing Crescent Moon. This Moon can be seen after the New Moon, but before the First Quarter Moon. The crescent will grow larger and larger every day, until the Moon looks like the First Quarter Moon. This Moon is known as a Waxing Gibbous Moon. This Moon can be seen after the First Quarter Moon, but before the Full Moon. The amount of the Moon that we can see will grow larger and larger every day. ("Waxing" means increasing, or growing larger.) This Moon is called a Waning Gibbous Moon. This Moon can be seen after the Full Moon, but before the Last Quarter Moon. The amount of the Moon that we can see will grow smaller and smaller every day. ("Waning" means decreasing, or growing smaller.)
This Moon is called the Waning Crescent Moon. This Moon can be seen after the Last Quarter Moon and before the New Moon. The crescent will grow smaller and smaller every day, until the Moon looks like the New Moon.   E. Causes  of  the  Moon  Phases   1. So  here's  where  the  phases  of  the  moon  come  from:  Unless  it  moves  behind  the   Earth,  half  of  the  moon  (that  faces  the  Sun)  is  always  lit  by  the  Sun.  That's  why   the  moon  always  appears  like  a  bright  round  ball  in  the  left  video.  But  look  at   where  your  green  city  viewpoint  is  in  the  left  video;  sort  of  off  to  the  side  of  the   moon.  You  are  not  looking  at  the  moon  directly-­‐-­‐  from  the  side,  you  see  part  of   the  lit  side,  and  part  of  the  dark  side.  How  much  of  each  depends  on  exactly   where  you  are,  and  where  the  Sun,  Moon,  and  Earth  are.  What  the  moon  would   look  like  from  your  green  city  is  shown  in  the  right  video.   F. Video  on  Earth,  Moon  and  Sun   1. 12  months   2. 28  days   3. 24  hours   4. Earth     i. What  is  it?  The  Earth  is  a  planet  made  of  rock,  air  and  water.     ii. What  shape  is  it?  Roughly  spherical,  like  a  slightly  squashed  ball.   iii. How  big  is  it?  It  has  a  circumference  of  about  40,000  km   iv. How  fast  does  it  move?  The  Earth  travels  around  the  Sun  once  every  year,   at  the  speed  of  about  100,000  km  per  hour.   v. Did  you  know?  The  Earth  also  spins  on  its  axis  (an  imaginary  line  through   its  center)  once  every  24  hours   5. Moon   i. What  is  it?  A  large  ball  of  rock  that  moves  around  the  Earth   ii. What  shape  is  it?  Roughly  spherical   iii. How  big  is  it?  About  a  quarter  of  the  size  of  the  Earth   iv. How  fast  does  it  move?  The  Moon  travels  around  the  Earth  once  every  28   days,  at  a  speed  of  over  3,000  km  per  hour   v. Did  you  know?  Sometimes  we  see  the  whole  Moon,  and  sometimes  we  see   only  part  of  the  Moon,  This  is  because  of  the  way  the  light  from  the  Sun   falls  on  it   6. Sun   i. What  is  it?  The  Sun  is  a  star,  it  is  very  hot  and  it  gives  us  heat  and  light   ii. What  shape  is  it?  Roughly  spherical   iii. How  big  is  it?  The  Sun  is  more  than  100  times  bigger  than  the  Earth   iv. How  hot  is  it?  15  million  degrees  at  the  center   v. Did  you  know?  Our  Sun  is  just  one  of  about  400  thousand  million  stars  in   the  galaxy  we  call  the  Milky  Way
