Consider the following statements:
1. Ocean currents are slow-surface movement of water in the ocean. 2. Ocean currents assist in maintaining the Earth's heat balance 3. Ocean currents are set in motion primarily by prevailing winds 4. Ocean currents are affected by the configuration of the ocean
Which of these statements are correct?
Ocean currents are not slow most of the time and can be subsurface current also. So, statement '1' is wrong. But '2', '3' and '4' statements are correct.

Sun's halo is produced by the refraction of light in:
Sun halo also known as 22 degree halo, the ring is caused by sunlight passing through ice crystals in cirrus clouds with in the Earth's atmosphere.

Consider the statements:
Assertion (A) : During the neap tides. The high tide is lower and the low tide is higher than usual. Reason (R) : The neap tide, unlike the spring tide, occurs on the new moon instead of on the full moon.
The sun, the earth and the moon come in the position of quadrature (form-a right angle) on seventh and eighth day of every fortnight of a month and thus the tide producing forces of the sun and the moon works in opposite direction, causing low tide. This is lower in height than the normal tide and is called neap tide. But the spring tide occurs during full moon and are called high tides.

Identify the correct order of the process of soil-erosion from the following:
The correct order of soil erosion process is splash erosion, sheet erosion, rill erosion and gully erosion. Splash occurs when the raindrop hits the surface; explosive impact soil into individual particles. Sheet erosion is the detachment of soil particles by rain drop and their removal down slope by water flowing overland as a sheet in definite channels. Rill erosion refers to the development of small ephemeral concentrated flow paths which function as both sedimentary source and sediment delivery systems for erosion on hill slopes. Sheet erosion removes the this top layer by raindrop kill or orion occurs in lines which are less than 30 cm deep when these rills are deeper than 30 forming channels are called as gully erosion. Gully erosion occurs when water flows in narrow channels after heavy rain and melting snow.

Consider the following statements made about sedimentary rocks:
1. Sedimentary rocks are formed at earth's surface by the hydrological system 2. Formation of sedimentary rocks involves the weathering of preexisting rocks 3. Sedimentary rocks contain fossils 4. Sedimentary rocks typically occur in layers

If the stars are seen to rise perpendicular to the horizon by an observer, he is located on the:
If the stars are seen to rise perpendicular to the horizon by an observer then the observer is at the equator because celestical equator is an imaginary circle around the sky directly above the earth's equator. It is always 90º from the pole. All the stars rotate in a path that is parallel to the celestical equator.
