What is precipitation short answer Class 7?
Answer: The sun’s heat vaporises water into vapour. This vapour cools down and condenses to become clouds. This may then fall on the surface of Earth in the form of rain, snow or sleet. This phenomenon of water falling back onto the surface of the earth in the form of rain, snow or sleet is called precipitation.
What are tides and how are they caused Class 7 very short answer?
Tides are caused by the strong gravitational pull exerted by the Sun and the Moon on the Earth’s surface. Formation of high and low tides: The water of the Earth closer to the Moon gets pulled under the influence of Moon’s gravitational force, thereby causing a rise of ocean water towards the Moon.
What is precipitation Chapter 7 chapter5?
Ans. (a) Falling of moisture in the form of rainfall, snow, fog, sleet, and hailstone is termed as precipitation.
How are clouds formed 7 geography?
1. Clouds: They are formed when water vapour condenses over dust particles and forms water droplets. 2. Dew: It is formed when the water vapour comes in contact with cool surfaces like grass and leaf and forms tiny water droplets.
What is water cycle short answer?
The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes. Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.
Why was Bengal temple built?
Answer: Temples were built in Bengal to house the local deities who had gained the recognition of the Brahmanas.
How tide are formed?
The moon’s gravitational pull on the Earth and the Earth’s rotational force are the two main factors that cause high and low tides. The side of the Earth closest to the Moon experiences the Moon’s pull the strongest, and this causes the seas to rise, creating high tides.
What is precipitation answer?
Precipitation is any liquid or frozen water that forms in the atmosphere and falls back to the Earth. It comes in many forms, like rain, sleet, and snow. Along with evaporation and condensation, precipitation is one of the three major parts of the global water cycle.
What is dew and fog?
Fog is an atmospheric condition characterized by the cloud appearing close to or at the earth’s surface. Dew is the condensation that occurs due to temperature drops to the dew point. Calm winds lead to the formation of dew. When the air above the ground cools under light wind speeds, fog also forms.
How is rainfall caused?
Rain is liquid precipitation: water falling from the sky. Raindrops fall to Earth when clouds become saturated, or filled, with water droplets. Millions of water droplets bump into each other as they gather in a cloud. When a small water droplet bumps into a bigger one, it condenses, or combines, with the larger one.
What is convective rain?
Convection Precipitation. Convective precipitation results from the lifting or upward movement of air that is warmer and lighter than its colder denser surroundings (figure 3). Typically, on a hot day the ground surface becomes heated, as does the air in contact with it.
How is rain formed in steps?
What causes rain? Clouds are made of water droplets. Within a cloud, water droplets condense onto one another, causing the droplets to grow. When these water droplets get too heavy to stay suspended in the cloud, they fall to Earth as rain.
How did the regional cultures evolve?
Regional cultures today are often the product of complex processes of intermixing of local traditions with ideas from other parts of the sub-continent.
How did regional cultures grow around religious traditions?
In several regions, regional cultures developed around religious traditions. The local people made a wooden image of the deity which, originally a local God, came to be identified with Vishnu. Temple became the centre of pilgrimage.
What is a bore in a river?
A tidal bore, often simply given as bore in context, is a tidal phenomenon in which the leading edge of the incoming tide forms a wave (or waves) of water that travels up a river or narrow bay reversing the direction of the river or bay’s current. It is a strong tide that pushes up the river, against the current.
What are waves in geography?
Waves are essentially the movement of water molecules within the ocean, and are restricted to the surface layers of our oceans and seas. They involve the circular orbit of water molecules and are the agents of coastal change. Waves vary enormously in size and character, from ocean to ocean.

What is the water cycle class 7 Geography?
NCERT Book Solutions Class 7 Geography Chapter 5 Our Earth’s surface is covered with 71 percent of water. Water cycle is the process by which water continually changes its form and circulates between oceans, atmosphere and land. The major sources of freshwater are the rivers, ponds, springs and glaciers.
