If the Earth had no Moon, what changes would be immediately noticeable? Choose ALL the correct answers!
Without Earth's tilted axis from the collision that created the Moon, we would not have seasons on Earth.
Without the Moon's gravity to stabilize Earth's tilt, our axis would shift.
Nights would be absolutely black with darkness.
Tides would be lower overall because the Moon's gravity would not pull on the oceans.
How are eclipses named?
Eclipses are named for what is casting the shadow.
Eclipses are named for whatever is covered in shadow, whatever is blocked.
Eclipses are named for astronomers who discovered them.
Eclipses are named after constellations in which they occur.
The reason that most solar winds do not disrupt electricity on the Earth is due to the Earth’s ______.
poles
magnetic field
stratosphere
auroras
Which layer of the Sun can be seen here?
We can only photograph it on Earth during a total solar eclipse.
Why do we have tides here on Earth?
We have tides because of how the Moon's gravity pulls on different parts of the Earth.
The Sun has more mass than Earth. Why doesn't the Moon orbit the Sun instead of Earth?
The moon is closer to Earth than the Sun so its gravitational pull is more.
It does orbit the Sun because of Earth's orbit around the Sun.
The Earth has a greater mass than the Sun.
Earth's magnetic field is so strong it pulls the Moon close.
In which area of the sun does gas rise as it heats up, then fall back down as it cools?
the core
the radiative zone
the convective zone
the corona
Over 99% of the solar system's total mass is in the Sun.
Critical Thinking Question: How did this contribute to the development of our solar system?
Mark more than one correct answer!
The Sun's gravity caused
As the object with the greatest mass, all of the planets orbit the Sun.
When drawing a "flat Earth" model to show Earth's tilted axis, which tools and steps must you use to be sure that your model is accurate?
You must mark THREE correct answers.
Use a protractor to mark the degrees.
Use a compass to draw a perfect circle.
Mark the the circle at 0 degrees at the top and 23.5 degrees at the bottom.
Draw a line connecting 0 & 23.5 degrees
Draw a straight line through the circle's center, connecting your marks for 23.5 degrees.
Why does Earth have a magnetic field?
Earth is surrounded by magnetic chunks from asteroids.
Earth's crust is ALL metallic ores. As tectonic plates move, they have a magnetic effect.
It is a solid, metallic inner core, surrounded by a liquid, metallic outer core that moves.
Earth pulls in the Sun's energy and uses it to make magnets in space.
