Light that is not spread out forms a narrow more intense pattern. Spread out light forms a wider less intense pattern

What happens when light is not spread out? What happens when the light is more spread out? Relate this idea to the sun's energy and Earth.

March

n the Northern Hemisphere, spring begins in

northern seas at night

Because it does not shift position, the North Star became a guide by which sailors could navigate the

year

Because the sun is not up in the sky very long, there is less daylight time during this time of

nearly parallel

Because the sun is so far away, the rays that strike Earth are very nearly/exactly parallel

Year

But as you move north or south away from the equator, the sun's path in the sky changes during the month/year.

Latitude on Earth

By taking a measure of the angle of elevation of the North Star, you can determine your what

No,because Earth's North Axis turns toward the north star.

Could a person at the South Pole see the North Star? Explain.

longer

In the summer, the sun has a longer path across the sky, which means the sun is in the sky for a longer/shorter period of time.

lesser

In winter, when the sun is lower in the sky, the sun's energy reaches Earth at a greater/lesser angle.

Warmest

After Spring comes summer. It is the_______ season.

The four seasons of Uranus would be different from Earth's because the tilt of Uranus is different. Uranus would experience seasons, because its tilt remains constant as it orbits the sun. But because Uranus's tilt with respect to the sun is different from Earth's, the seasons on Uranus would be different than the seasons on Earth.

An image shows the orbit of Uranus around the sun. How would the seasons on Uranus compare to the seasons of Earth?

Yes. Yes. They are different in the Winter,Spring,Summer, and, Fall

Are constellations visible in the early evening? If they are then are they different? When are they different?

Spring

As temperatures warm, snow melts and what begins?

directly overhead

At the North Pole, the North Star is seen directly overhead/in a straight path.

Earth. As shown in the activity, when the sun is overhead, the energy on each square meter is more intense—the light is more/less spread out

The photo shows the December solstice. The Northern Hemisphere is in winter and the Southern Hemisphere is experiencing summer. The Southern Hemisphere is in summer and the Northern Hemisphere is in winter.

Explain what is shown in a photo where the Earth's left side is covered?

Winter is generally cold and may bring snow and ice. Summer is hot and may bring tornadoes. Fall is where the leaves fall and it has a little breeze. Spring is where everything starts to bloom and feels warm.

Explain winter,summer,fall,and spring.

Winter

Fall (also called autumn) follows, temperatures get cooler, and then what begins again?

September

Fall in the northern hemisphere begins when?

It is warmer in summer than in winter. Why?

stars in the night sky also appear to move.

Just as the sun appears to move in a path across the sky,........................................

The sun

One of the easiest questions ever: What does light come from?

Sun

So, people who live on or near the equator feel the intense energy of the sun/moon.

less

Solar energy passes through more atmosphere when it strikes Earth at a lesser angle, making the sun's rays striking Earth more/less intense.

South Pole

The sky seen from the North Pole is completely different than the sky seen from the

When viewed from the same location at the same time of night, stars visible in December may or may not be seen in March. Stars visible in December may or may not be visible in the sky in March. Some stars may have moved out of the visible sky. Some stars may have moved across the sky but can still be seen. Some stars can be seen from a location all year long. Some stars can be seen from both the Northern Hemisphere and the Southern Hemisphere, depending on how far away from the equator the two locations are.

What is true about the stars?

The weather is going to head into spring and the snow is starting to melt.

What seasonal changes do you see where you live?

The stars,moon,constellations,and sometimes planets.

When you look at the night sky, what do you see?

When it is summer in the Northern Hemisphere of Uranus, the Southern Hemisphere has no daylight hours. The picture shows that when the Northern Hemisphere of Uranus is tilted toward the sun, its Southern Hemisphere is always in darkness.

Which of these describes the seasons on Uranus?

Because Earth rotates once every 24 hours

Why do the stars appear to move across the sky every night?

It is Because of Earth's rotation. Because Earth changes it's position , the stars we see change as well.

Why do you see different stars in spring's night sky than in fall's night sky? Explain.

Earth's Rotations

If you are on the North or South Pole, the stars will appear to rotate around a point directly above your head because of

NOT always in the same position in the night sky.

If you look for the big dipper, you will see that it is.........

When people talk about shorter days they actually mean the number of daylight hours.

One day is defined as an amount of time equal to 24 hours. Why do you think people say winter days are shorter than summer days?

North

People who live at the north/south pole would see the sun on this same day as very low in the sky.

seasons

These changes in the sun's path across the sky and the angle at which sunlight strikes Earth affect the changes in temperature that occur across the seasons/years.

Equator is straight up towards the Sun. Poles are straight toward the Horizon. Someone between is pointing at an angle, but not overhead directly

Think about a person at the equator, a person at the North Pole, and a person somewhere in between. Each person points toward the sun. Describe where in the sky they are pointing.

the year

Weather conditions and daily temperatures at any location on Earth follow a predictable cycle throughout the year/the day.

As you move from the equator to the poles, the rays strike at

spherical and parallel

Because of Earth's flat/spherical shape, these straight/parallel rays strike Earth most directly at the equator.

sky

Because of Earth's rotation, we see the sun appear to move across the

During the course of its path or revolution around the Sun, it is either tilted toward or away from the Sun. During the summer months, in the Northern hemisphere, although Earth is further away from the sun than in winter, it is actually tilted more directly toward the sun.

How do the length of days and the path of the sun across the sky help to explain why winter is cold with shorter days?

The longer the sun is in the sky, the more time Earth has to absorb energy provided by the sunlight. The higher the sun is in the sky, the more intense the energy received because the light travels through less atmosphere and the light is not as spread out.

How does the path of the sun affect the energy received by Earth at any particular location on Earth

We would have the same light rays. It would all start at the same time. There would be no seasons.

If Earth were flat instead of curved, how would that affect temperatures from pole to pole? Explain how the range of temperatures at noon at different latitudes on a cube-shaped planet would compare to temperatures on our spherical Earth.

Higher

In summer, the sun goes higher/lower in the sky.

more

In summer, when the sun is higher in the sky, the solar energy is less/more intense.

Earth's north axis points to it

In the Northern Hemisphere, the North Star's position remains fixed in place throughout the year because of what?

Summer sunsets in the Northern Hemisphere are north of west, while winter sunsets are south of

change and seasons The moving Earth gives the impression that the Big Dipper is moving in a circular pattern across the seasons.

The Big Dipper appears to keep/change its position from season to season. The Big Dipper seems to move in a circular pattern as the seasons/years change

nighttime hours

There is less time for the sunlight to heat up Earth during the daytime and more time for Earth to cool during the longer daytime hours/nighttime hours.

A spread out area

The amount of energy striking a smaller area will result in warmer temperatures than the same amount of energy striking a spread out area/a small area.

Winter

The angle at which sunlight strikes Earth influences Earth's temperatures, making it hot in summer and cold in Summer/Winter

changes in the length of the sun's path across the sky and changes in the height of the sun in the middle of the day.

There are two reasons why we receive different amounts of the sun's energy in summer and winter. What are they?

Because of the snow and because The sun is in a low place.

There is a photo with trees snow and the sun in a low place. How do you know that this photo was taken in winter?

Sunlight striking the equator is less spread out, so the intensity of the energy received at the equator is greater than at polar regions. Sunlight striking the equator passes through less atmosphere to reach the equator than it does to reach the poles, so more sunlight gets through. This makes locations around the equator hotter.

What describes the differences in sunlight striking Earth at different latitudes?

The number of daylight hours in June and changes in yearly temperatures across the seasons. The number of daylight hours and the changes in temperature across the seasons are affected by both Earth's tilt and Earth's revolution. The length of each season is determined by Earth's revolution.

What is affected by Earth's tilt?

The stars visible at night gradually shift as Earth travels in its yearly orbit around the sun and the sun blocks different stars from being seen from Earth at different times of the year. Also, Earth faces different parts of the night sky while it orbits the sun. The longer the sun is in the sky, the more time Earth has to absorb energy provided by the sunlight. The higher the sun is in the sky, the more intense the energy received because the light travels through less atmosphere and the light is not as spread out.

Why are different stars seen in the sky in different seasons?

Earth's tilt affects the temperature differences experienced at different locations on Earth across the seasons.

Why is Earth's tilt responsible for the seasons?

December

Winter in the northern hemisphere begins when?

which stars stay visible all year

Your location on Earth determines

season

a division of the year that is characterized by recurring weather conditions, and determined by both Earth's tilt relative to the sun and Earth's position in its orbit around the sun
