Summary. The four inner planets have shorter orbits, slower spin, no rings, and they are made of rock and metal. The four outer planets have longer orbits and spins, a composition of gases and liquids, numerous moons, and rings. The outer planets are made of hydrogen and helium, so they are called gas giants.
What are the dominant features on the surface of Mercury?
There are three major types of surface features on Mercury: Smooth plains that resemble Lunar maria. Intercrater plains, which are pocked with small craters and occupy about 70% of the surface that we have examined. Rugged highlands that bear some resemblance to the corresponding regions on the Moon.

The four outer planets have longer orbits and spins, a composition of gases and liquids, numerous moons, and rings. The outer planets are made of hydrogen and helium, so they are called gas giants.
Which planet is an inner planet and which one is an outer planet explain your answer?
Mercury, Venus, Earth, and Mars are the planets closest to the Sun. They are called the inner planets. The inner planets are made up mostly of rock. The outer planets are Jupiter, Saturn, Uranus, and Neptune.
What is Mercury’s surface made of?
The surface is rich in sulfur, about 20 times richer than the surfaces of Earth, the Moon, and Mars. Messenger also found low surface abundances of titanium and iron. Mercury seems to have formed in conditions much more reducing—i.e., those in which oxygen was scarce—than other terrestrial planets.
Is Mercury a rocky planet?
Mercury is a rocky planet, also known as a terrestrial planet. Mercury has a solid, cratered surface, much like the Earth's moon.
What is Pluto made of?
Pluto's surface is composed of a mixture of frozen nitrogen, methane, and carbon monoxide ices. The dwarf planet also has polar caps and regions of frozen methane and nitrogen. Pluto has three known moons, Hydra, Nix, and Charon.
What is Jupiter made of?
The composition of Jupiter is similar to that of the Sun – mostly hydrogen and helium. Deep in the atmosphere, pressure and temperature increase, compressing the hydrogen gas into a liquid. This gives Jupiter the largest ocean in the solar system – an ocean made of hydrogen instead of water.
How might dams built on the Tigris and Euphrates rivers in Turkey affect agriculture in Syria and Iraq?
Turkey's dam and hydropower constructions on the Tigris and Euphrates are estimated to have cut water to Iraq by 80 percent since 1975, jeopardizing agriculture and natural habitats. Iraq has also been adversely affected by dam projects and agricultural developments in Iran.
How many dams are in the Euphrates river?
Atatürk Dam lies in the midst of the five dams currently operational on the Euphrates river. The Karakaya Dam and Keban Dam are located upstream of Atatürk, while the Karkamış and Birecik dams are situated downstream.
What sorts of things has space exploration taught us as a society what do we now know about Earth and our solar system that we did not know before exploring space?
Space exploration allows us to prove or disprove scientific theories developed on Earth. Studying the solar system, for example, has brought us insights into such phenomena as gravity, the magnetosphere, the atmosphere, fluid dynamics and the geological evolution of other planets.
Who made Earth?
When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun.
How do the inner planets differ from the outer planets in terms of composition size and formation?
Summary. The four inner planets have shorter orbits, slower spin, no rings, and they are made of rock and metal. The four outer planets have longer orbits and spins, a composition of gases and liquids, numerous moons, and rings. The outer planets are made of hydrogen and helium, so they are called gas giants.
What are the inner planets and the outer planets of the solar system How are they different from each other?
While the inner planets are the ones before the asteroid belt in our solar system and near to the sun; they are Mercury, Venus, Earth, and Mars; the outer planets are Jupiter, Saturn, Uranus, Neptune and the dwarf planet Pluto.
Why are the inner planets rocky while others are mostly in gaseous form Class 11?
The temperature of the early solar system explains why the inner planets are rocky and the outer ones are gaseous. As the gases coalesced to form a protosun, the temperature in the solar system rose. In the inner solar system temperatures were as high as 2000 K, while in the outer solar system it was as cool as 50 K.
What is Uranus made of?
Kid-Friendly Uranus Uranus is made of water, methane, and ammonia fluids above a small rocky center. Its atmosphere is made of hydrogen and helium like Jupiter and Saturn, but it also has methane. The methane makes Uranus blue. Uranus also has faint rings.
What is the Venus made of?
Venus has the most massive atmosphere of all the terrestrial planets. Its gaseous envelope is composed of more than 96 percent carbon dioxide and 3.5 percent molecular nitrogen. Trace amounts of other gases are present, including carbon monoxide, sulfur dioxide, water vapor, argon, and helium.
What color Is Uranus?
blue-green color Uranus gets its blue-green color from methane gas in the atmosphere. Sunlight passes through the atmosphere and is reflected back out by Uranus' cloud tops. Methane gas absorbs the red portion of the light, resulting in a blue-green color.
What is Venus made of?
Venus has the most massive atmosphere of all the terrestrial planets. Its gaseous envelope is composed of more than 96 percent carbon dioxide and 3.5 percent molecular nitrogen. Trace amounts of other gases are present, including carbon monoxide, sulfur dioxide, water vapor, argon, and helium.
Where did the water that was used to irrigate southern Mesopotamia come from explain who made use of the water and how the water made the land fertile?
Two rivers, the Tigris and the Euphrates, regularly flooded the region, and the Nile River also runs through part of it. Irrigation and agriculture developed here because of the fertile soil found near these rivers. Access to water helped with farming and trade routes.
How did the Tigris and Euphrates rivers affect the growth of civilizations in Mesopotamia?
The presence of those rivers had a lot to do with why Mesopotamia developed complex societies and innovations such as writing, elaborate architecture and government bureaucracies. The regular flooding along the Tigris and the Euphrates made the land around them especially fertile and ideal for growing crops for food.
How many dams are in Pakistan?
150 dams Pakistan is an agricultural country, depending heavily on water resources for irrigation. Interestingly, Pakistan has around 150 dams spread across all the provinces.
What tools do we have for exploring our solar system and how have they been useful?
Telescopes use lenses and mirrors to see beyond Earth's borders. Scientists learned quite a bit with telescopes. This paved the way for more space exploration. Humans have taken trips to the Moon and dozens of space shuttle flights.
Why do we explore space reading answers?
Human space exploration helps to address fundamental questions about our place in the Universe and the history of our solar system. Through addressing the challenges related to human space exploration we expand technology, create new industries, and help to foster a peaceful connection with other nations.
