Why is lithosphere important for the progress of human Class 7?
Lithosphere plays an important role in our life. It provides us forests, grassland for grazing , land for agriculture and human settlements. It is also a treasure of various minerals. Question 2.
Why is the lithosphere important?
Lithosphere is important because it is the outermost crust of the Earth.It comprises the crust and upper part of upper mantle. Lithosphere serves as a source of minerals, source of fuels and provides nutrients for plants. It also serves as a natural habitat for many organisms including humans.
What do humans use the lithosphere for?
We use the lithosphere for different types of purposes from food for us to fuel for cars. Our lithosphere contains lots of valuable items which we can use in everyday life. We use these land use methods to make the stuff we need: Agriculture, Livestock/Grazing, Forestry, Mining, Urbanization, and Recreation.
What is the importance of atmosphere Class 7?
The atmosphere contains the air that we breathe; protects us from the harmful radiation of the Sun; helps to keep the planet’s heat on the surface, and plays a very important role in the water cycle.
How does the atmosphere protect the Earth Class 7?
Hint: The atmosphere protects us from ultraviolet rays from a layer which is present in the stratosphere which begins about 10-16 km above earth’s surface. -The ozone lawyer acts as a protective shield which protects life on earth. Without the ozone layer life would not have existed.
What is importance of lithosphere very short answer?
It is an irregular surface with various landforms such as mountains, plateaus, desert, plains, valleys, etc. Lithosphere plays an important role in our life. It provides us forests, grassland for grazing, land for agriculture and human settlements. It is also a treasure of various minerals.
What is the effect of lithosphere?
The lithosphere also interacts with the atmosphere, hydrosphere, and cryosphere to influence temperature differences on Earth. Tall mountains, for example, often have dramatically lower temperatures than valleys or hills.
What is the main importance of 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.
What are 3 ways the atmosphere is important to life on Earth?
Three Ways That the Atmosphere Helps Living Things Survive on…
- Protection. The atmosphere blocks out harmful rays from the sun.
- Water. The Earth’s atmosphere contains water.
- Oxygen and Carbon Dioxide. Life on Earth needs the atmosphere to breath.
- Other Benefits. The atmosphere contains a large amount of nitrogen.
What is the short note of 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.
How do humans affect the lithosphere positively?
Humans can affect the lithosphere by farming, building structures (urbanization), mining and all manner of activities that change the original structure of the crust and upper mantle. The results of such activities can permanently change the lithosphere and may ultimately lead to erosion (broken rocks) and flooding.
What is the reason why lithosphere thickens?
Oceanic lithosphere thickens as it ages and moves away from the mid-ocean ridge. This thickening occurs by conductive cooling, which converts hot asthenosphere into lithospheric mantle, and causes the oceanic lithosphere to become increasingly dense with age.
What are the two main components of lithosphere?
The lithosphere is the rocky outer part of the Earth. It is made up of the brittle crust and the top part of the upper mantle.
What are 3 functions of the atmosphere?
The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth’s surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation …
