What number of what subatomic particle determines the identify of an element: proton, electron, or neutron?
The number of protons determines the identify of an element.
True or False: The Moon causes night time to occur on the Earth.
False
What causes the different seasons on the Earth?
The TILT OF THE EARTH ON ITS AXIS and the revolution of the Earth around the Sun causes the Seasons.
What causes the different phases of the Moon?
The REVOLUTION OF THE MOON AROUND THE EARTH causes the different moon phases.
Where would the Sun be located in the image shown? (Top, Bottom, Left, or Right)
To the RIGHT
What is the net force acting on the box?
40N to the left.
What would happen if the Earth's rotation on its axis was faster?
If the rotation of the Earth was faster, the length of a day would be shorter.
What season is best described as having short days and long nights? Spring, Summer, Fall, or Winter
Winter has short days and long nights.
What is this moon phase?
Waxing Crescent
What hemisphere does this Daylight hour graph best represent: Northern or Southern, and why?
The Southern Hemisphere because winter in the Southern Hemisphere is in June, July, and August and winter has short days and long nights.
Describe the reactivity of this atom: highly reactive, reactive, or non-reactive.
The element has 7 valence electrons (Group 17) so it is HIGHLY REACTIVE.
What would happen if the rotation of the Earth on its axis was slower?
If the rotation of the Earth was slower, the length of a day would be longer.
What season is shown in the Northern Hemisphere?
Summer is shown in the Northern Hemisphere.
What moon phase comes next?
Waning Gibbous comes next.
A student drew the following model of the Earth to show what they learned in Science class. How could the student draw the model more accurately?
The student should draw the Earth with a tilted axis.
How many atoms are in the chemical formula?
3Na2H2(SO4)3
There are 57 atoms.
What would happen if the Earth did not rotate on its axis?
One side of the planet would be constant day and the other side of the planet would be constant night.
What season comes next in the Southern Hemisphere?
Spring comes next in the Southern Hemisphere.
What moon phase comes before the one shown?
Third Quarter Moon comes before a waning crescent moon.
What moon phase occurred at Day 24?
Third/Last Quarter
What is the FORCE acting on the object?
F=MxA
F=10kg x 3m/s2
F=30N
What causes the Day/Night cycle on the Earth?
The rotation of the Earth on its axis causes the Day/Night cycle.
What season came before the one shown in the Northern Hemisphere?
Fall comes before the season shown in the Northern Hemisphere.
If there is a New Moon on December 7, approximately what date can we expect a Full Moon?
Approximately December 21 (or about 14 days later)
The diagram shows what an astronaut would see from space as they were over the planet Earth. What moon phase would people on the planet Earth be seeing?
They would see the New Moon. (New Moon is always when the Moon is between the Sun and the Earth.)
