AMSTI 6th Grade Formative Set-Researching the Sun-Earth-Moon

Front

What is Earth's magnetic field?

Back

Earth's magnetic field is a protective shield generated by the movement of molten iron in its outer core, which helps protect the planet from solar wind and space weather.

Front

How does Earth's magnetic field affect satellites?

Back

Earth's magnetic field can sometimes cause problems with satellites and other communication systems due to interference.

Front

What is the significance of the poles of Earth's magnetic field?

Back

The poles of Earth's magnetic field can reverse at predicted intervals, which is known as geomagnetic reversal.

Front

What does the model with iron filings and a magnet represent about Earth's interior?

Back

The model shows that Earth has a liquid outer core and a solid inner core, with the magnetic field being stronger at the poles than at the equator.

Front

Why is an extra day added to the calendar every four years?

Back

An extra day is added every four years because the orbit of Earth around the Sun is not exactly 365 days.

Front

What causes the Big Dipper to appear to change positions in the sky?

Back

The Big Dipper appears to change positions in the sky due to Earth's rotation on its axis.

Front

What phase of the Moon is when it is not visible from Earth?

Back

The phase of the Moon when it is not visible from Earth is called the New Moon.

Front

What is the relationship between Earth's tilt and seasons?

Back

Earth's tilt on its axis causes the changing seasons as different parts of the planet receive varying amounts of sunlight throughout the year.

Front

What is solar wind?

Back

Solar wind is a stream of charged particles released from the upper atmosphere of the Sun, which can affect planets and their magnetic fields.

Front

How does the gravitational pull of the Sun affect Earth?

Back

The gravitational pull of the Sun keeps Earth in orbit around it, influencing its movement and position in space.
