How earth movement around the sun affect the seasons?

The Earth is tilted on its axis of rotation. However the angle of tilt remains the same regardless of where the Earth is in the annual cycle around the sun. This means that, for a period of half of the year, each hemisphere is angled towards the sun more than the other. It therefore gets warmed more, which causes the seasons. So, when the northern hemisphere is tilted towards the sun, for half of the year it receives more sunlight than the southern hemisphere and is therefore warmer. = Spring and Summer.

What planet is considered Earth's sister planet and why?

Venus is considered Earth's sister planet because of its similar size, mass, and composition. It is also located relatively close to Earth in the solar system. Additionally, Venus and Earth are often referred to as sister planets because of their comparable gravity and proximity to the Sun.

When was Earth dicorverd?

Earth was not "discovered" since it has always existed. The scientific understanding of the Earth and its place in the universe has evolved over time through observations and research by scientists.

How long is one year on mars in comparison to earth years revolution one day on your planet?

One year on Mars is approximately 687 Earth days long. A day on Mars, known as a sol, is about 24 hours and 39 minutes. This means a year on Mars is almost twice as long as an Earth year in terms of days.

What layer of the earth can be 5000 Celsius?

Venus has a surface temperature close to this.

Venus has a surface temperature close to this.

Venus has a surface temperature close to this.

Venus has a surface temperature close to this.

Earth completes one rotation every?

day. Geosynchronous means it follows the Earth as it spins. It is therefore always above the same point on the earth's surface. Since the Earth spins once in a day the satellite must orbit once in a day.

Is water the lightest liquid on earth?

No, water is not the lightest liquid on Earth. Liquid hydrogen and liquid helium are lighter than water because they have lower densities.

Why is it important for humans to explore other planets besides the earth?

i think that humans will need to colonize to other planets in the future because if green house affects continue and people continue to pollute the world as they are, the earth could become a nasty and dangerous place to live and it will not be very suitable to sustain life anymore.

Do you live on a finite planet?

Yes, Earth is a finite planet with limited resources and capacity to support life. It is important to be mindful of our impact on the environment in order to ensure a sustainable future for generations to come.

Can earth survive without convection?

No, Earth relies on convection to transfer heat from its core to the surface, driving geological processes like plate tectonics and volcanic activity. Without convection, Earth's surface would become too cold and life as we know it would not be sustainable.

Why cant we bring earth life to mars?

Bringing Earth life to Mars could contaminate the planet and complicate our ability to search for native life. Introducing Earth organisms to Mars could also disrupt the Martian ecosystem, which we are still striving to understand. Therefore, strict protocols are in place to prevent forward contamination.

Why planet earth is called as the most favored planet?

Because it took a lot of favorable conditions for Earth to have any life on it-- it would be almost impossible to have life here if not for being just this distance from the sun and having a large magnetic field to deflect the nastier parts of solar radiation.

And, for reasons still unclear, Earth has a lot of water compared to other planets, and it's mostly usefully liquid.

Compare to Mars: no decent magnetic field, so it's blasted by solar radiation, and what water there is, is frozen, which is hard for any life form to do anything with. Not a favorable planet. (But it's a second-best, next to Mercury and Venus!)

However, life in forms that we're not familiar with could well exist in parts of the atmospheres of Jupiter, Saturn etc, and some of their (many many) moons. Maybe those environments are actually better for life than here on our big wet rock.

Why is earth a rock?

Earth is known as a rocky planet because it is primarily composed of silicate minerals and metals. Its solid surface is made up of a combination of rocks and minerals, which give it its characteristic features. Several geological processes over millions of years have shaped Earth into the rocky planet we see today.

Why only in Hinduism we believe in astrology whereas the rest of the population in this earth are living their lives according to their own pattern.?

Belief in astrology is not exclusive to Hinduism; it is practiced in various cultures and religions around the world. People may follow astrology for guidance, insight, or entertainment, regardless of their religious beliefs. Many factors, such as cultural traditions and personal experiences, influence an individual's beliefs and practices regarding astrology.

What would happen on earth that would not happen on mars because there are no plate movements there?

Without plate movements on Mars, earthquakes and volcanic activity would not occur like they do on Earth. The lack of plate tectonics also means that Mars does not have the same kind of geological processes shaping its surface, such as mountain building or the creation of deep ocean basins. Additionally, without plate movements, Mars does not experience the recycling of materials through subduction zones like on Earth.

How large is Earth compared to Saturn?

Its about 120,000 km in diameter, compared with Earths 12,700km diameter. So its diameter is about 9.5 times as big as the earths. But when you look at the volume (a three dimensional measurement of size) it has a volume of around 763 times that of earth.

Why is there so many countries in the world?

Countries exist as a way to define and govern a specific group of people within a certain territory. Historically, countries have formed through a combination of factors such as cultural, historical, political, and economic differences. Over time, these factors have led to the creation of numerous countries around the world.

Why does it get bright in the daytime OR why does it get dark at night?

Everything is moving at random at different speeds, directions, and distances! The moon orbits the earth about every 28 days, and, at the same time, the Earth is rotating about every 24 hours. It takes the Earth about a year to orbit the sun. The rotation of the Earth gives us day and night in a 24 hour period. If the moon did not orbit, the moon would seem to act more like the sun, and be more predictable as it seems to pass overhead, every 24 hours. The moon could care less if we are seeing it in the day or night! Your question really is asking why isn't the sun and moon paying attention to what the other one is doing? Other planets and moving objects will also seem to pass overhead, all on their own schedules, both day and night. It all depends on the distance and speed of their orbits, complicated by the rotation of the Earth. They are all doing their own things. It takes Jupiter over 11 years to orbit the sun!

Why are the temperatures on each of the other terrestrial planets more extreme than the temperatures on earth?

The temperatures on other terrestrial planets are more extreme due to differences in atmospheres, distances from the sun, and compositions. For example, Venus has a thick atmosphere that traps heat, resulting in extremely high temperatures. Mars, on the other hand, has a thin atmosphere that cannot retain heat well, leading to very cold temperatures. Mercury experiences extreme temperature fluctuations due to its lack of atmosphere and close proximity to the sun.

How many grams of francium exist in the earth's crust at any one time?

It is estimated that there are around 340 grams of francium in the Earth's crust at any given time. Francium is a highly unstable and rare element, with a half-life of only about 22 minutes, making it very hard to find in nature.

What in Earth's interior is like a boiling pot?

The outer core of the Earth, composed of molten iron and nickel, is often likened to a boiling pot due to its intense heat and churning motion. The movement of this liquid outer core generates the Earth's magnetic field through a process known as geodynamo.

Where is England in south Asia?

England is not a part of South Asia I'm afraid.

It happens to be an island off the western coast of Europe.

How long is the world in yards?

The world's equatorial circumference is approximately 24,901 miles, which converts to about 43.5 million yards.

What is further from Earth - Jupiter or Mars?

Jupiter is further from Earth than Mars. Jupiter is the fifth planet from the sun, while Mars is the fourth planet.

How do the parts of yours model compare to the actual parts of the earth?

The parts of my model are simplified representations of the Earth's structure. While my model may include the Earth's layers such as the crust, mantle, outer core, and inner core, it does not capture the complexity and intricacies of the actual Earth's components, which include varied compositions, densities, and physical properties. Keep in mind that models are used to represent real-world phenomena in a simplified manner for better understanding.
