What best describes the surface of the planet Earth?

Earth is a rocky planet with a solid and dynamic surface of mountains, canyons, plains and more. Most of our planet is covered in water.

What is Earth’s surface of the planet?

Surface: Total Surface Area: about 509 600 000 square km (197 000 000 square miles). Area of land: 148 326 000 km2 (57 268 900 square miles), this are 29% of the total surface of Planet Earth.

Which of the following best describes a planet?

A planet is a celestial body that (a) is in orbit around the Sun, (b) has sufficient mass for its self-gravity to overcome rigid body forces so that it assumes a hydrostatic equilibrium (nearly round) shape, and (c) has cleared the neighbourhood around its orbit.

Which of the following best describes the surface of planet Earth also known as the blue planet?

Planet Earth has been called the “Blue Planet” due to the abundant water on its surface. Here on Earth, we take liquid water for granted; after all, our bodies are mostly made of water. However, liquid water is a rare commodity in our solar system.

What is the surface of the earth made up of Class 9?

​​The earth is made up of three different layers: the crust, the mantle and the core. This is the outside layer of the earth and is made of solid rock, mostly basalt and granite. There are two types of crust; oceanic and continental. Oceanic crust is denser and thinner and mainly com​posed of basalt.

What are 3 important surface features of a planet?

Common rigid surface features include: Impact craters (though rarer on bodies with thick atmospheres, the largest being Hellas Planitia on Mars) Dunes as found on Venus, Earth, Mars and Titan. volcanoes and cryovolcanoes.

What are the 4 surfaces of the Earth?

The structure of the earth is divided into four major components: the crust, the mantle, the outer core, and the inner core.

Which of the following best describes Earth’s atmosphere?

Which answer best describes Earth’s atmosphere? Mostly Nitrogen with about 21% oxygen.

Which of the following best describes what makes planet Earth habitable?

What makes the Earth habitable? It is the right distance from the Sun, it is protected from harmful solar radiation by its magnetic field, it is kept warm by an insulating atmosphere, and it has the right chemical ingredients for life, including water and carbon.

Which of the following best describes why we have seasons on Earth?

The seasons are caused by the tilt of the Earth’s rotational axis away or toward the sun as it travels through its year-long path around the sun. The Earth has a tilt of 23.5 degrees relative to the “ecliptic plane” (the imaginary surface formed by it’s almost-circular path around the sun).

Why is the earth also called The Blue Planet describe the composition of the hydrosphere?

Over 71 percent of the Earth is covered with water. Therefore from outer space it appears blue and so Earth is called the ‘Blue Planet’.

Which best describes how Earth differs from the other planets in our solar system?

Perhaps the most strikingly unique feature of Earth is its vast oceans, which cover 70% of the planet’s surface. Earth is the only world in our solar system with liquid water at its surface today.

Why is the earth called The Blue Planet Class 6 short answer?

The planet looks blue from outer space since two-thirds of the surface is covered with water, so it is called a blue planet. That is 71% of the earth is covered by water.

What are examples of Earth’s surface?

Earth’s surface is the arena for most life and all human activity, yet what lies beneath our feet is as mysterious as it is familiar. Earth scientists or not, we recognize hills, mountains, glaciers, deserts, rivers, wetlands, and shorelines.

Which of the following is a planet?

[1] The eight planets are: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Which of the following best describes the motion of the planets?

The answer is “elliptical.” Stars, planets, moons, and other objects in space orbit around each other due to gravity. This type of motion is called revolution.

Which of the following best describes the outer planets?

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 of the following best describes a planet’s orbit around the sun?

Kepler’s First Law: each planet’s orbit about the Sun is an ellipse. The Sun’s center is always located at one focus of the orbital ellipse.
