IMPACT CRATER Bowl-shaped depressions on the surface of the Moon that are formed by meteor and comets crashing into the Moon.
RAY Long trails of debris that radiate outward from a Moon crater.
REGOLITH Dust and small pieces of rock that cover the surface of the Moon.
SUMMER SOLSTICE The longest day of the year which happens when the Sun is as far north of the equator as possible, around June 21.
WINTER SOLSTICE The shortest day of the year which happens when the Sun is as far south of the equator as possible, around December 21.
AUTUMNAL EQUINOX The time in the fall when day and night are equal in length because the Sun is directly over the equator, around September 21.
VERNAL EQUINOX The time in the spring when day and night are equal in length because the Sun is directly over the equator, around March 21.
SYNCHRONOUS ROTATION When the orbit and rotational periods of the Moon (or any other orbiting body) are equal.
SOLAR ECLIPSE When the Moon passes between the Sun and the Earth and blocks out all or part of the Sun.
LUNAR ECLIPSE When the Earth passes between the Sun and the Moon and the Earth’s shadow falls on the Moon. Only happens during a full moon.
Ch 28 Tools of Astronomy. Ecliptic is the plane in which Earth orbits about the Sun. is the plane in which Earth orbits about the Sun.
The Moon By the awesome J.J.. What would happen with no moon? Orpheus crashes into earth. Then a big explosion.
Two reasons the Earth has seasons: degree tilt 2. Revolution around sun.
Earth and Moon Notes Chapter 24. GRAVITY Causes spherical shape of planets Decreases as items move farther apart Increases with size of objects.
Concept Map. This affects the angle of the Sun’s rays and the length of the daylight hours.
HOW DO THE SUN & MOON AFFECT EARTH? Eclipses Day & Night Moon Phases Changing of the seasons.
B ENCHMARK T EST R EVIEW. H OW THE E ARTH M OVES Rotation: The spinning of Earth along its imaginary axis at a 23.5 o angle Revolution: Earth’s yearly.
The Earth and Moon. Review What is an Equinox? What is a Solstice? What is an Equinox? What is a Solstice? When do they occur? What causes the seasons?
24.2 Sun and Seasons hill.com/sites/ x/student_view0/cha pter2/seasons_interactive.html.
The Seasons We experience Seasons because the Earth does not receive the same amount of solar radiation at all times. When the Northern Hemisphere is tilted.
What causes seasons? The tilt of the Earth on its axis The 23.5° tilt is caused by the interaction between the Moon and the Earth.
Seasons and the Angle of Solar Radiation Rotation: the time it takes a planet to rotate (spin) once on its axis. For Earth = 1 day.
Spring “Vernal” Equinox Spring begins March 20 at 9:57 AM PDT Equal Days Equal Nights Sunrise: 709 AM Sunset: 718 PM Data for Sacramento.
The Seasons A Northern Hemisphere Perspective. The Seasons Definitions Axis: An imaginary axle that passes through the North and South Poles Rotation.
Chapter 23 Sun, Earth, Moon System. Position? Center of the universe? No, the Sun is the center of our solar system; Earth travels around the Sun. Shape?
How does the Earth move in space? What causes the cycle of the seasons on Earth?
The Four Seasons. The Earth’s axis is tilted to 23.5 degrees.
Astronomy The study of the moon, stars, and other objects in space Study the movements of the sun, and moon as they appear to travel across the sky Will.
Basics of the Sun Sun is a star that is at the center of our solar system Sun is a star that is at the center of our solar system It is a medium sized,
Time Remaining:Seconds To an observer on Earth, the bright and dark portions of the.
Welcome to Astronomy! Find your place in Space!. Astronomy The study of the Moon, Stars, and other objects in space.
Science Chapter 10 & 11 Study Guide. Chapter 10 In a solar eclipse, the moon passes between Sun and Earth. The imaginary line that Earth rotates around.
Earth Earth is part of our solar system and revolves around our sun. It is the third rocky inner planet away from the sun in a zone called the “Goldilocks.
Earth, moon, and the sun. Key terms: Solstice: day when the sun appears farthest North or South of the equator. Northern hemisphere receives the most.
Earth in Space Section 1-1 P Astronomy The study of space. The study of the Moon stars and other objects in Space.
Today’s Agenda… Bellringer: Identify each as rotation or revolution (this is not multiple choice) –A. Takes 24 hours –B. Spins on Axis –C. Takes 365 ¼.
Earth’s Seasons. Rotation 1.The imaginary line that passes through Earth’s center and the North and South poles is called Earth’s axis. 2.Earth spinning.
1 Ambition – Respect - Excellence Ardrossan Academy Dead Earth Subtopic – SPACE – Earth, Moon & sun.
Astronomy Chapter 1: Earth in Space Astronomy Study of moon, stars, and objects in space Not “astrology”
Unit 9: Earth Cycles Vocabulary. Axis Imaginary line about which an object rotates.
UNIT 09 NAME THIS PHASE. *Full moon Another word for Vernal?
Indirect Direct Light is spread over a larger area (scattered) and it is less intense. Light covers a smaller area and it is more intense (stronger).
OBJECTIVE 1/21/14 TLW, discern the effects of cyclical patterns and movements of the Earth and moon in relation to the Sun, by becoming familiar with terminology.
Earth Moon and Sun Interactions. Lunar and Solar Eclipses A lunar eclipse occurs when the Earth passes between the Moon and the Sun, and the Earth's shadow.
Motions and Their Effects
Definition: The spinning of the Earth on its axis, causing night and day. Extra Fact: One of these equals about 24 hours.
The Earth and its Motions Science 8 Astronomy Notes Page 6.
Earth-Moon Systems By Gina Wike. Earth’s Shape A sphere is a round 3 dimensional object whose surface at all points is the same distance from the center.
Earth, Moon, and Sun Chapter 5 Lesson 1-3. Earth in Space Chapter 5 Lesson 1 Page 182.
Seasons. What is the difference between Earth’s ROTATION & REVOLUTION? Rotation- Earth spinning on its axis (day and night) Revolution- The Earth orbiting.
The Reason for the Seasons Explain the motions of Earth and the Moon and effects of these motions as they orbit the Sun (including day, year, phases.
Earth, Moon, Sun Vocabulary. Astronomy The study of the moon, stars and other objects in space.
SOLAR SYSTEM CHAPTER EARTH MOTION AND SEASONS A. Earth’s Physical Data 1. spherical shape (almost) 2. bulges at equator 3. gravity = 9.8 m/s 4.
The Tilt of Earth Terms Earth’s tilt 23.5°
Review: T I D E S SEASONS MOON PHASES. WHY DO WE HAVE TWO (2) HIGH TIDES AND TWO (2) LOW TIDES EACH DAY?
Long ago, in a galaxy far, far away…
Movements of the Earth The Earth’s Motion in Space.
Seasons. Seasons happen because of Earth’s tilt on its axis AND revolution around the Sun. Axis- imaginary line drawn from the north to the south pole.
