Which of the following is Earth’s densest atmospheric layer?
The troposphere is the densest atmospheric layer, compressed by the weight of the rest of the atmosphere above it.
Which of the following includes all of the water on or near Earth’s surface?
The hydrosphere includes water that is on the surface of the planet, underground, and in the air. A planet's hydrosphere can be liquid, vapor, or ice. On Earth, liquid water exists on the surface in the form of oceans, lakes and rivers.

What is in the thermosphere?
In the upper thermosphere, atomic oxygen (O), atomic nitrogen (N), and helium (He) are the main components of air. Much of the X-ray and UV radiation from the Sun is absorbed in the thermosphere. When the Sun is very active and emits more high-energy radiation, the thermosphere gets hotter and expands or "puffs up".
What are the major regions of atmosphere?
The atmosphere can be divided into layers based on its temperature, as shown in the figure below. These layers are the troposphere, the stratosphere, the mesosphere and the thermosphere. A further region, beginning about 500 km above the Earth's surface, is called the exosphere.
Where is the majority of water on Earth’s surface located?
The oceans The oceans are, by far, the largest reservoir of water on earth — over 96% of all of Earth's water exists in the oceans.
Is the geosphere?
The geosphere is the earth itself: the rocks, minerals, and landforms of the surface and interior. Below the crust – which varies in depth from about 5 km beneath the ocean floor to up to 70 km below the land surface, temperatures are high enough for deformation and a paste-like flow of elements.
What is the thermocline layer?
A thermocline is the transition layer between warmer mixed water at the ocean's surface and cooler deep water below.
Where is thermocline located?
thermocline, oceanic water layer in which water temperature decreases rapidly with increasing depth. A widespread permanent thermocline exists beneath the relatively warm, well-mixed surface layer, from depths of about 200 m (660 feet) to about 1,000 m (3,000 feet), in which interval temperatures diminish steadily.
What kind of heat transfer occurs mostly on the earth’s surface?
Most of the heat transfer that is taking place on the earth is by radiation.
Which among the following is used to describe the type of heat transfer from a surface that has moisture?
Condensation. Condensation occurs when a vapor is cooled and changes its phase to a liquid. During condensation, the latent heat of vaporization must be released. The amount of the heat is the same as that absorbed during vaporization at the same fluid pressure.
What is in mesosphere?
Most meteors vaporize in the mesosphere. Some material from meteors lingers in the mesosphere, causing this layer to have a relatively high concentration of iron and other metal atoms.
What is in the exosphere?
The region above about 500 km is called the exosphere. It contains mainly oxygen and hydrogen atoms, but there are so few of them that they rarely collide – they follow "ballistic" trajectories under the influence of gravity, and some of them escape right out into space.
What is the most abundant element in the earth’s atmosphere?
nitrogen Gases. The most abundant naturally occurring gas is nitrogen (N2), which makes up about 78% of air. Oxygen (O2) is the second most abundant gas at about 21%.
What is the earth’s stratosphere?
The stratosphere is a layer of Earth's atmosphere. It is the second layer of the atmosphere as you go upward. The troposphere, the lowest layer, is right below the stratosphere. The next higher layer above the stratosphere is the mesosphere.
Which layer of the earth contains most of the water?
The hydrosphere is the layer of the earth where water is found. The oceans are where most of the earth's water is found, but water can also be found in lakes, rivers and below the ground. Water is also an essential habitat resource.
Where did the majority of water on Earth come from?
Currently, the most favored explanation for where the Earth got its water is that it acquired it from water-rich objects (planetesimals) that made up a few percent of its building blocks. These water-rich planetesimals would have been either comets or asteroids.
What is lithosphere and geosphere?
Summary. The lithosphere or geosphere is a shell of rocky planet, most rigid outer layer and solid part of the earth which constitutes crust and brittle mantle. The two major types of lithosphere are continental lithosphere and oceanic lithosphere.
What is in the lithosphere?
The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth's structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.
Which region is the thermocline most developed?
tropical regions In low latitude tropical regions the sea surface is much warmer, leading to a highly pronounced thermocline (Figure 6.2. 4).
What is the halocline layer?
halocline, vertical zone in the oceanic water column in which salinity changes rapidly with depth, located below the well-mixed, uniformly saline surface water layer.
What is the thermocline quizlet?
A thermocline (sometimes metalimnion in lakes) is a thin but distinct layer in a large body of fluid (e.g. water, such as an ocean or lake, or air, such as an atmosphere) in which temperature changes more rapidly with depth than it does in the layers above or below.
What is called the surface layer of the Earth?
The surface of the planet, where we live, is called the crust—it's actually a very thin layer, just 70 kilometres deep at its thickest point. The crust and the lithosphere below (the crust plus the upper mantle) is made of several 'tectonic plates'.
How is the Earth’s surface heated?
The heat source for our planet is the sun. Energy from the sun is transferred through space and through the earth's atmosphere to the earth's surface. Since this energy warms the earth's surface and atmosphere, some of it is or becomes heat energy.
Which of the following is described as the process of heat exchange between the Sun and the earth that controls the temperatures of the letter?
The Sun's rays take about 8 minutes to reach Earth's atmosphere. Which process describes the thermal energy transfer between the Sun and the Earth? Conduction.
What is known as stratosphere?
The stratosphere is a layer of Earth's atmosphere. It is the second layer of the atmosphere as you go upward. The troposphere, the lowest layer, is right below the stratosphere. The next higher layer above the stratosphere is the mesosphere.
What is the stratosphere made of?
What Is the Stratosphere Made of? The stratosphere is composed primarily of nitrogen and oxygen. It also consists of a layer known as the ozone layer, a blanket of ozone that absorbs harmful ultraviolet (UV) rays from the sun. Ozone is a chemical compound consisting of three oxygen atoms.
Where is thermosphere located?
The thermosphere is a layer of Earth's atmosphere. The thermosphere is located above the mesosphere and below the exosphere.
Where is the majority of water on Earth surface located?
the oceans The vast majority of water on the Earth's surface, over 96 percent, is saline water in the oceans. The freshwater resources, such as water falling from the skies and moving into streams, rivers, lakes, and groundwater, provide people with the water they need every day to live.
