All answers are correct except the option "avoiding soil compaction"

Soil compaction makes the soil cohesively bound and make them less available for erosion.

Crop rotation holds the soil by increasing soil productivity and increasing the plantation that holds the soil

Mulching is the strategy adopted at farmland where straw blend is spread-ed over the soil mass to avoid its erosion.

Wind breaks are used at farmland to avoid or reduce soil erosion

Increasing the vegetation mean increasing the plants which through their roots hold the soil and prevent it form being carried away.

What are the two important processes involved in lithification of sedimentary rocks?.

marin [14]

The two important processes involved in lithification of sedimentary rocks are compaction and cementation.

Fresh sediment is usually loose material filled with open spaces or pores filled with air or water. Lithification serves to reduce this pore space and replace it with solid mineral material. The main processes involved in lithification are compaction and cementation.

Compaction compresses the sediment to a smaller volume by packing the sediment particles more tightly, removing water from the pore spaces, or by reducing the pressure at the sediment particle contact points. Cementation involves filling the pore spaces with solid minerals that are either deposited from solution or allow particles of existing sediment to grow into the pores.

For much of South and Southeast Asia, winter is a period characterized by relatively dry conditions. True False

stepan [7]

For much of South and Southeast Asia, winter is a period characterised by relatively dry conditions is "true" statement.

<h3>Reason for Dry condition in South and Southeast Asia:</h3>

The South and Southeast Asian winters is characterised by relatively dry conditions. This is because of the trade winds blowing from the Northeast to Southwest over the Pacific Ocean from the subtropical high-pressure belt towards the equatorial lows.

Some characteristics of South and Southeast Asia are-

In general, Asia is demarcated by a continental climate in the interior parts of the continent.
This means there is a strong heating up of the landmass during summer months and a strong chilling of the continent during winters.
The relatively dry conditions as compared to summer is due to the dry wind which loses most of its moisture at the coasts while passing through the continental landmass.

Most of the time in the atmosphere, the upward-directed pressure gradient force is exceeded by the downward pull of gravity.

Lisa [10]

Answer:

Ture

Explanation:

The pressure gradient is the force that is produced due to the rotation of earth pressure cells that creates lighter air to move upwards and heavier to move downwards due to the difference in densities of air.

As the air above consists of lighter elements the oceanic air mostly consist of diatomic molecules of oxygen and nitrogen thus containing a large amount of water vapor, all these molecules have a mass that are pulled down by the gravity and this pull of gravity on columns of gas applies a force what we see an atmospheric pressure.

The gas particles and molecules of heavy and denser matter get stuck at the ground, similarly, as the air cools is descends and warm air rises. Thus upwards and downward motion of air causes convergence and divergence of molecules.

What is the shape of the planetary orbit around the sun

Anna [14]

Answer:

The answer is that the actual shape of the planetary orbit around the sun is elliptical.

Explanation:

The actual shape of the orbit of a planet around the sun is elliptical.

The assumption made by the Newton regarding the shape of an orbit of a planet around the sun was that the orbit of a planet around the sun is 'circular'.

Hope this helps!! ;)
