What is the summer and winter solstice?
The two solstices happen in June (20 or 21) and December (21 or 22). These are the days when the Sun's path in the sky is the farthest north or south from the Equator. A hemisphere's winter solstice is the shortest day of the year and its summer solstice the year's longest.
Does the axis go straight up and down or is it tilted?
The axis for the basketball is vertical (straight up and down), but Earth spins on an axis that is tilted —23.5 degrees to be exact. Earth's axis always points in the same direction. Because of this, the part of Earth that receives the most direct rays from the Sun changes as the Earth travels around the Sun.
Is the Northern Hemisphere tilted toward or away from the Sun?
Earth orbits at an angle, so half the year, the Northern Hemisphere is tilted toward the Sun — this is summer in the Northern Hemisphere, and winter in the Southern Hemisphere. The other half of the year, the Northern Hemisphere is tilted away from the Sun, creating winter in the north and summer in the south.
Which hemisphere gets more sunlight at time a 6 months?
The northern hemisphere is more directly exposed to the sun's rays during June and July (summer in the northern hemisphere, SF Fig. 6.11 A). The southern hemisphere receives less direct sunlight during these months, resulting in winter.
What is called equinox?
An equinox is an event in which a planet's subsolar point passes through its Equator. The equinoxes are the only time when both the Northern and Southern Hemisphere experience roughly equal amounts of daytime and nighttime. Illustration by Przemyslaw, courtesy Wikimedia.
What are the Four seasons?
The four seasons—spring, summer, fall, and winter—follow one another regularly. Each has its own light, temperature, and weather patterns that repeat yearly. In the Northern Hemisphere, winter generally begins on December 21 or 22.
Is winter cold or hot?
Winter is cold because the sun is farther away. Summer is hot because the sun is closer. Winter is cold because when it is winter the sun is further away than in the summer. So in the summer the sun is close to the Earth which makes it hot.
What if Earth had no tilt?
The tilt of Earth's axis is the main cause of the seasons. If Earth had no tilt, then the length of daylight and the intensity of solar heating seen by a person standing at a single place on the surface would be the same all year round.
What is on the equator?
The equator passes through 13 countries: Ecuador, Colombia, Brazil, Sao Tome & Principe, Gabon, Republic of the Congo, Democratic Republic of the Congo, Uganda, Kenya, Somalia, Maldives, Indonesia and Kiribati.
Does the equator have seasons?
Equatorial Climates Twice a year, during the spring and autumn equinoxes, the sun passes directly over the Equator. Even during the rest of the year, equatorial regions often experience a hot climate with little seasonal variation. As a result, many equatorial cultures recognize two seasons—wet and dry.
What Causes season?
As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons.
Which is longest day in year?
June 21 Summer officially kicks off in the Northern Hemisphere today (June 21), marking the longest day of the year. During the June solstice (or summer solstice), the sun reaches its highest and northernmost points in the sky.
What are the equator?
An equator is an imaginary line around the middle of a planet or other celestial body. It is halfway between the North Pole and the South Pole, at 0 degrees latitude. An equator divides the planet into a Northern Hemisphere and a Southern Hemisphere. The Earth is widest at its Equator.
How do you explain four seasons to a child?
The Earth has a tilt. The Earth sits on a slight tilt of about 23.5 degrees. Because of this tilt, different areas of the world are hit with more (or less) sunlight and warmth than others throughout the year. These changes in weather are broken up into four seasons: summer, fall, winter and spring.

Why is my body hot?
Your body works best at around 98.6 F. Higher than that and you may have a fever, which can make you hot and sweaty. This often happens as your body tries to fight off germs like viruses or bacteria. Fluids, rest, and over-the-counter meds can help.
Why do I feel cold?
Poor blood circulation Whether it's a decreased circulation or something that's blocking your circulation, poor blood flow is another potential cause of your chilly disposition. “People with a decreased circulation to their extremities are definitely going to feel cold, especially in their hands and feet,” says Dr.
What if Earth had 2 moons?
If Earth had two moons, it would be catastrophic. An extra moon would lead to larger tides and wipe out major cities like New York and Singapore. The extra pull of the moons would also slow down the Earth's rotation, causing the day to get longer.
What would happen if the Sun exploded?
So, if we had enough time to prepare, civilization could continue to live by moving underground into a huge network of fortified bunkers. Within a week after the explosion, the surface temperature on Earth would drop to -18°C (0°F). Within a year, temperatures would plummet to about -73°C (-100°F).
Is Equator hot or cold?
But why is the equator very hot and the poles very cold? There are several factors that influence the amount of sunshine received at various places on the earth. The major factor is that while the sun is overhead at the equator, it is at a rather slant angle at the poles.
Is the latitude?
Latitude is the measurement of distance north or south of the Equator. It is measured with 180 imaginary lines that form circles around the Earth east-west, parallel to the Equator. These lines are known as parallels. A circle of latitude is an imaginary ring linking all points sharing a parallel.
What causes the seasons answer key?
B. Earth's distance from the sun causes the seasons.
What is season short answer?
A season is a period of the year that is distinguished by special climate conditions. The four seasons—spring, summer, fall, and winter—follow one another regularly. Each has its own light, temperature, and weather patterns that repeat yearly. In the Northern Hemisphere, winter generally begins on December 21 or 22.
What is the darkest day?
December 21, 2020 The Winter Solstice is fast approaching. It's the northern hemisphere's shortest day and longest night, set to occur on Monday, December 21, 2020. This solstice occurs when the earth tilts on its axis, pulling the northern hemisphere away from direct sunlight.
Is 21 June the shortest day?
The winter solstice is the shortest day of the year. It usually falls on June 20 or 21 in the southern hemisphere. In the northern hemisphere, today is the summer solstice, the longest day of the year. Last night was the longest night of the year, in that it was darker for longer than any other date.
Is equator hot or cold?
But why is the equator very hot and the poles very cold? There are several factors that influence the amount of sunshine received at various places on the earth. The major factor is that while the sun is overhead at the equator, it is at a rather slant angle at the poles.
What are seasons short answer?
The Short Answer: Earth's tilted axis causes the seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
How do you explain the 4 seasons?
Seasons. Seasons are largely due to factors surrounding the Earth's tilted axis as it revolves around the sun. A season is a period of the year that is distinguished by special climate conditions. The four seasons—spring, summer, fall, and winter—follow one another regularly.
Why do I feel hot around my crush?
You start feeling all flustered whenever they're around. Your heart beats faster and your palms start to sweat. This happens when an adrenaline-like neurotransmitter called norepinephrine is released.
