Moonquakes also tend to occur at great depths, about midway between the lunar surface and its center. Earthquakes rumble as these plates snag and slip past each other. Venus is a similar size to Earth, but is closer to a perfect sphere than our planet. Roughly 100 miles 160 km above Earth, the air is so thin that can zip through the atmosphere with little resistance. At the bottom of the continental crust, temperatures reach about 1,800 degrees Fahrenheit 1,000 degrees Celsius , increasing about 3 degrees F per mile 1 degree C per km below the crust.
What Are the Physical Characteristics of the Earth?
The moon also helpfully pulls the ocean's tides, which scientists suggest might have been the perfect place for early life to begin evolving to survive on land. Over long periods of time, the remnants of this life, rich in carbon, are carried back into the interior of the Earth and recycled. The most obvious source of energy is a planet or moon's host star, as is the case on Earth, where sunlight drives photosynthesis in plants. Without the action of plate tectonics, there would be no way to recycle this carbon, and the Earth would become an overheated, hellish place. Archived from on 10 March 2013.
This simply means that the rounded shape has a slight bulge towards the equator. Like Venus and Mars, Earth has mountains, valleys, and volcanoes. There is more to learn about the planets than just their position and name. It is made up of three layers: the core, the mantle, and the crust. Mars has a number of interesting features that make it one of the most studied planets in the solar system. The atmosphere of Mars includes a thin layer of clouds, but the atmosphere is gradually disintegrating due to solar winds.
Along these plate boundaries, , , , and formation can occur. Magnetic field Earth's magnetic field is generated by currents flowing in Earth's outer core. Earth was generally believed to be until the 16th century, when scientists first conclusively demonstrated that it was , comparable to the other planets in the Solar System. Choi, Live Science Contributor on. Unlike the other ringed planets, the rings go vertically rather than horizontally, and the poles are on the sides rather than at the top and bottom! A study from 2016 suggested that tilted all planets, including Earth's, by about six degrees.
Violent bursts of radiation could have scoured life from Earth in its early, fragile stages. It revolves around the Sun slowly, taking 84 years to complete one orbit. One of the special features that are attributed to the planet Venusis that it is the second planet from the Sun. Earth is one special planet. Archived from on 3 April 2013.
Archived from on 17 January 2010. Our ozone layer is being destroyed because we are not protecting the Earth. As these plates collide, tear apart, or slide past each other, they give rise to our very active geology. In addition to being our home and the place where life as we know it originated, it remains the only planet we know of where life thrives. Mars is a little more than half the size of the Earth, having a diameter of 6,790 kilometers. The four major water bodies on Earth are the Arctic, Atlantic, Pacific, and Indian oceans.
Important changes in crystal structure within the mantle occur at 410 and 660 km 250 and 410 mi below the surface, spanning a that separates the upper and lower mantle. Red shows where gravity is stronger than the smooth, standard value, and blue shows where it is weaker. Precipitation patterns vary widely, ranging from several meters of water per year to less than a millimeter. At the planet's heart lies the inner core, a solid sphere of iron and nickel that's 759 miles wide and as hot as 9,800 degrees Fahrenheit. As with and , Earth was a in : the were listed by as among the of , and later included , a giantess often given as the mother of.
D Differentiate among earth layers according to their physical properties. The oceans are also a reservoir of dissolved atmospheric gases, which are essential for the survival of many aquatic life forms. Imagine a basketball spinning on your finger. Earth, our home, is the third planet from the sun. As a result, the mean annual air temperature at sea level decreases by about 0. It is the second smallest planet in the Solar system after Pluto, and is about a third of the size of Earth. The average temperature on Earth is about 59° F 15° C.
