What two properties are most important in determining the surface temperature of a planet?

Which two properties are most important in determining the temperature of a planet?

On global scales, three things can affect this energy flow and therefore, the average global surface temperature. As shown in the figure below, they are the planet’s distance from the Sun, the planet’s surface reflectivity (albedo), and the planet’s atmosphere (through a process called the greenhouse effect).

What determines the surface temperature of a planet?

The factors that determine the temperature are a complex balance between the amount of heat received and that lost. The heat received by a planet varies with its distance from the Sun, for it is the Sun’s radiation which is by far the greatest source of planetary warming.

What are two factors that affect the average temperature of the planet?

Factors Controlling Temperature Distribution

• The latitude of the Place.
• The altitude of the Place.
• Distance From The Sea.
• The presence of warm and cold ocean Currents.
• Local Aspects.

What are the two causes of internal heating in terrestrial planets?

What are the sources of internal heat for terrestrial planets? differentiation, collisions from other bodies, radioactive decay, gravitational compression.

How can we determine the temperature of a star or surface of a planet quizlet?

What is the sequence in order of decreasing temperature? The way astronomers determine the surface temperature of a star which is determined by the spectral lines present in a stars spectrum.

Where do secondary atmospheres come from?

A secondary atmosphere is an atmosphere of a planet that did not form by accretion during the formation of the planet’s star. A secondary atmosphere instead forms from internal volcanic activity, or by accumulation of material from comet impacts.

What determines a planet’s atmosphere?

There are two primary factors: size and distance from the Sun. Gravity helps planets and moons to hold on to their atmospheres, so small planets/moons such as Mars and the Moon have thin atmospheres.

Which two factors are most important to the existence of plate tectonics on Earth?

What two factors are most important to the existence of plate tectonics on Earth? mantle convection and a thin lithosphere. Mantle convection helps move the plates, and the plates probably exist because the lithosphere was thin enough to break into these plates.

What planets have primary atmospheres?

Planets such as Jupiter and Saturn have primary atmospheres. Primary atmospheres are very thick compared to secondary atmospheres like the one found on Earth. The primary atmosphere was lost on the terrestrial planets due to a combination of surface temperature, mass of the atoms and escape velocity of the planet.

What is the most important geological process in the solar system?

Collisions are at the core of solar system formation (Birth of Worlds), and continue to be one of the most important processes throughout our solar system.

What planets have secondary atmospheres?

The Solar System has three planets—Earth, Venus, and Mars—that have atmospheres derived from H₂-free solids (secondary atmospheres), and four giant planets whose atmospheres are derived from protoplanetary nebula gas (H₂-dominated primary atmospheres) (1, 2).

What makes planet Earth different from other planets in the solar system?

How is Earth different from other planets? It differs from the other planets because it has liquid water on its surface, maintains life, and has active plate movement. It rotates on its axis every 24 hours (a day) and revolves around the Sun every 365 days (a year). The Earth has one moon.

What features or characteristics does Earth have that makes it different from Venus and Mars?

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. Scientists believe that Mars and Venus may have long ago had oceans, but these are long gone.

What is the 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 are the two main gases that make up most of the Earth’s atmosphere?

Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions.

What is the most important component of the atmosphere in terms of percentage?

Nitrogen and oxygen, which make up more than 99% of Earth’s atmosphere, have a bigger influence on climate than other components of the atmosphere.
Composition of Earth’s atmosphere.

What does the air contain Class 2?

Ans: Air contains Gases, water vapour, dust, snacks and germs. 2.

Which is a variable gas near the earth’s surface?

Variable Gases

These include carbon dioxide, methane, ozone, water vapor, and particulates among others. Even though they represent a tiny portion of the atmosphere as a whole, they exert a great control over our environment.

Why are variable gases important?

Water vapor and carbon dioxide are the most important of the variable gases because (1) they are the most abundant variable gases and (2) they both act as greenhouse gases, due to their ability to absorb infrared (IR) radiation, which causes the Earth’s surface to be warmer than if there was no atmosphere.

Which two gases were in Earth’s atmosphere right after Earth was formed?

Comparison of Earth’s prebiotic and modern atmospheres. Before life began on the planet, Earth’s atmosphere was largely made up of nitrogen and carbon dioxide gases. After photosynthesizing organisms multiplied on Earth’s surface and in the oceans, much of the carbon dioxide was replaced with oxygen.

What variable gas can have the largest concentration in Earth’s atmosphere?

nitrogen

By far, the most abundant gas in the Earth’s atmosphere is nitrogen, which accounts for about 78% of the mass of dry air.

What are the 3 most abundant gases in Earth’s atmosphere?

Nitrogen, oxygen and argon are the three most abundant elements in the atmosphere, but there are other key components that are required for supporting life as we know it on earth. One of those is carbon dioxide gas. Carbon dioxide makes up 0.04 percent of the Earth’s atmosphere.

Which two layers increase in temperature as altitude increases?

Temperature increases as you gain altitude in the stratosphere and the thermosphere. Temperature decreases as you gain altitude in the troposphere and mesosphere.

What are the four main variable gases that are present in the lower atmosphere?

Table 1 lists the eleven most abundant gases found in the Earth’s lower atmosphere by volume. Of the gases listed, nitrogen, oxygen, water vapor, carbon dioxide, methane, nitrous oxide, and ozone are extremely important to the health of the Earth’s biosphere.

What is the importance of atmospheric gases in the atmosphere?

The atmosphere is made of gases that are essential for photosynthesis and other life activities. The atmosphere is a crucial part of the water cycle. It is an important reservoir for water, and the source of precipitation. The atmosphere moderates Earth’s temperature.

Which two gases are the primary components of clean dry air choose two?

What are the two most abundant compounds in the modern atmosphere that are two major components of clean dry air? Nitrogen and Oxygen make up 99% of the volume of clean air. Nitrogen (78%) and oxygen (21%).
