Exploration 1 (A)
Mostly, matter and energy in the Earth-sun system is concentrated in the (Earth/sun).
What is the sun?
The distance between Earth and the sun remains the same throughout the year. (True or False)
What is false.
The main source of energy for living things on Earth.
What is the sun?
The amount of energy emitted by the sun changes over time. (True or False)
What is true?
A gas composed of molecules that absorb and radiate infrared radiation.
What is a greenhouse gas?
The (Earth/sun) has a greater average density.
What is the Earth?
Tides are an example of how Earth interacts with which two celestial bodies?
What are the sun and the moon?
The Earth systems affected by the sun.
What are atmoshpere, hydrosphere, lithosphere (or geosphere), and biosphere?
Changes in the eccentricity of Earth's orbit can affect the differences between seasons. (True or False)
What is true?
A dark area of the photosphere of the sun that is cooler than the surrounding areas.
What is a sunspot?
The two elements that mostly make up the Earth's atmosphere?
What is nitrogen and oxygen?
The changing gravitational interactions between the moon, sun, and Earth cause the difference between these tides.
(Hint: NOT high and low tides)
What are the spring and neap tides?
The total amount of solar energy is greater in the (tropical region/polar region).
As the sun ages, it is becoming (hotter and brighter / cooler and less bright).
What is hotter and brighter?
The otion of the axis of a spinning body such as the wobble of a spinning top.
What is precession?
Earth's axis is (perpendicular/not perpendicular) to its path around the sun.
What is not perpendicular?
The two motions a planet makes in space.
What are straight forward and straight toward the sun?
A model showing the ways that energy moves to and from Earth.
What is the Earth's energy budget?
Daily Double
The amount of energy emitted by the sun changes over approximately this amount of time.
What is a cycle of about 11 years?
The solar radiation (energy from the sun) that reaches earth.
What is insolation?
The Earth's axis is constantly pointed toward this star.
What is Polaris or the North Star?
Due to this uniform motion, a planet doesn't fall into the sun.
What is inertia?
In this month, the South Pole is pointing toward the sun at such an angle that it experiences a full 24 hours of daylight.
What is the month of December?
Changes due to sunspot activity affect Earth's climate by comparing the graphs of sunspot cyles and average _______ change over time.
What is global temperature?
A stream of charged particles continuously flowing outwards from the Sun into space
What is solar wind?
