Moon Features/Exploration
The ______________ missions in the 1960’s and 70’s put scientists on the moon to study its geology.
The moon’s dark surfaces are called ___________ which are made of solidified volcanic rock.
The moon does not have its own _______________. The moon is the farthest that any human has
ever _____________. The moon formed when a small planetesimal
_________ the Earth and splashed off a piece.
Eclipses
Label the diagram below with the following. Lunar or Solar Eclipse Umbra Penumbra
Tides
Tides on Earth are caused by the ________________ of the moon and its position.
The moon is the main cause for tides, but the gravity of the ____________ is also a small factor.
There are _______ high tides and _______ low tides in a day.
Each month, there are two ____________ tides and ___________ tides.
The ______________ range is greatest during a spring tide.
It would be in your best interest to understand and diagram the differences between spring and neap tides.
Models of the Solar System
Put the following solar system models in chronological order: Ptolemy's geocentric model Copernicus’ heliocentric model Kepler’s planetary laws of motion
Features of the Sun
Label the parts of the sun •The sun is made up of two main elements:
• __________• __________
•The process of ____________ is how the sun generates energy.
Features of the Sun, 2
_________________ are dark, cooler spots on the sun’s surface.
_________________ create solar winds that can disrupt communication and weather patterns on Earth.
Arc shaped flares are called _____________________.
Seasons
The Earth’s _____________ and ___________ of its axis causes seasons. The tilt is _________ degrees.
Label the seasons based on the Earth’s position. What time of
day is the sun closest
to being directly over
head? _____________
Revolution
One full revolution of the Earth around the sun takes __________ days.
The Earth’s revolution around the sun is _________________ shaped.
The ____________ model is the belief that the sun revolved around the Earth. The true nature of the solar system is that it is ______________, putting the sun in the center.
Planets
Label the picture and write one fact about each planet. Color inner planets red and outer blue.
Comets
Put a 1 in the box that points to the Dust Tail. Put a 2 in the box pointing to the Plasma tail. Put a 3 in the box pointing to the Coma. The _________ tail always points away from the
sun while the __________ tail always trails the comet.
Earth Impacts
Meteoroids are traveling towards Earth but haven’t entered the atmosphere, yet.
Meteors are flashes of light or “shooting stars” from the burning up of meteoroids in the atmosphere.
Meteorites are meteors that actually come in contact with earth. Draw each of these 3 below.
Solar System Formation
All the planets are roughly the same _________.
Be familiar with the diagram below:
Distances
1 light year = distance light __________ in 1 year.
1 AU = distance between _______ and ________.
What unit would you use to measure the distance between Earth and: The moon ___________ The Sun ___________ Polaris ___________ Mars ___________
Stars
Give an example of each of the following: A galaxy: __________________ A star: __________________ A constellation: __________________ A circumpolar star: __________________ A star system: __________________
Galaxies
Look at the shapes of galaxies. Which shape is our galaxy?
____________ is the force that holdsour galaxy together.
HR Diagram
In the box below, draw a simple HR diagram.
Red Shift
______________ is the use of light spectrum emissions to determine the composition of stars.
We can use red shift and blue shift to describe a stars _________________.
If the star is moving towards us, it has a _________ shift. This means the light wavelengths are becoming shortened.
If the star is moving away from us, it has a __________ shift. This means the light wavelengths are becoming ________________.
Most stars show red shift, supporting Hubble’s _______________________ theory.
Magnitude
Magnitude is another name for ______________.
A stars ________________ magnitude refers to it’s actual brightness.
________________ magnitude refers to how bright a star appears to be.
Use these two terms to compare our Sun to Betelgeuse (supergiant): ____________________________________________
____________________________________________
Atmosphere
Circle the layer where the majority of weather takes place.
Put hearts around the layer
that is least dense. Put a rectangle around the
layer that contains ozone. Draw a line that describes
temperature change through the
layers.
Humidity and Precipitation
List the changes of state that water goes through on Earth. ________________ ________________ ________________ ________________
____ _____is the temperature that water condenses on or near Earth’s surface.
Air that cannot hold any more water vapor is called ___________________.
What tool is used to measure humidity? __________________
Air pressure
A __________________ is used to measure air pressure. Which of the following will decrease air pressure?
increased latitude increased elevation increased humidity decreased elevation
Air will always move from and area of ___________ pressure to an area of ___________ pressure.
Wind speeds are greatest when isobars are _____________ together.
High pressure = ____________ / clear weather
Low pressure = ____________/ stormy weather
