Seasons

• The season is caused because of the tilted axis

• When the North is tilted toward the sun it is summer. More direct rays and longer days

• Summer solstice- Northern Hemisphere-June 21. Southern Hemisphere December 21

• Winter Solstice- Northern Hemisphere December 21. Southern Hemisphere June 21

• Equinox occurs when neither end is tilted toward or away from the sun

Multiple Choice

Seasons are caused by

• rotation on it axis

• distance from the sun

• the tilted axis

Multiple Choice

The longest day of the year is?

• summer solstice

• winter solstice

• fall equinox

Multiple Choice

Multiple Choice

Why is the equator the warmest?

• its closest to the sun

• its far from the sun

• it receives the most direct sunlight

Orbits

• Gravity and Inertia keeps objects in orbit

• Inertia- Tendency of a moving object to continue moving in a straight line

• Gravity - force that attracts all object

• Gravity strength is affect by mass and distance

• Shape of orbit- circular ellipses

Multiple Choice

The shape of the orbits of planets

• long

• elliptical

• circles

Multiple Choice

Factors that keep Earth in orbit

• tilted axis

• mass and gravity

• gravity and inertia

Multiple Choice

The strength of gravity depends on

• a rotation

• mass and distance

• weight and speed

Tides

• Moon -greatest effect on tides

• High tide - Part of earth facing the moon

• Tides changes about every 6 hrs

• Spring Tide- Moon and sun in a straight line. Produce highest high tide

• Neap Tide- Moon and sun at 90 degree angle. Produce low high tide and normal low tide

• spring tide during new and full moon

• neap tide during first and third quarter

Multiple Choice

What is a difference between spring and neap tides?

• Spring tides occur when the earth and sun are IN LINE with the new or full moon.

• Spring tides occur when moon in 3rd or 1st quarter phases

• Spring tides are LOWER than neap tides

• Spring tides occur in Spring and neap tides can occur in any season

  HIDE ANSWER

Multiple Choice

What type of tides would this arrangement of earth-moon-sun create?

• spring tide

• neap tide

• daily tide

Dropdown

When the sun, moon, and Earth are aligned in a straight line, and there are​ higher than normal high tides this is called

Select answer
