why does grass grow well in places where there are long dry periods followed by brief rainfall?

Answers

Answer 1

Grass is well adapted to survive in areas with long dry periods followed by brief rainfall due to its ability to tolerate drought stress. During long periods of drought, grasses become dormant and reduce their growth rate, conserving energy and water resources.

They also lose their leaves to reduce water loss through transpiration. When rainfall occurs, grasses respond by rapidly growing new leaves and stems. This is possible due to their ability to absorb water and nutrients quickly and efficiently.

In addition, grasses have extensive root systems that enable them to access water from deeper soil layers where moisture may be available even during dry periods. This helps them to survive longer without rainfall.

Furthermore, grasses have a C4 photosynthetic pathway that is more efficient than the C3 pathway used by most other plants. This allows grasses to continue photosynthesis during times of water stress, which is critical for their survival.

The ability of grasses to tolerate drought stress and respond quickly to rainfall is key to their success in areas with long dry periods followed by brief rainfall. This adaptation allows them to maintain their productivity and provide important ecosystem services such as erosion control, nutrient cycling, and forage for livestock.

describe what eventually happens to widening crust along a boundary.

Answers

Along a boundary where crust is widening, a process called divergence occurs. As the crust moves apart, several geological phenomena take place.

Firstly, a rift forms, creating a gap or rift valley between the separating crustal plates. This rift is often accompanied by volcanic activity, as magma rises to the surface through the fractures in the crust. This leads to the formation of new volcanic features such as shield volcanoes or lava flows.

As the crust continues to separate, the rift valley widens, and the gap between the plates becomes filled with molten rock or magma. Over time, this magma cools and solidifies, forming new oceanic crust. This process is known as sea-floor spreading and results in the creation of new oceanic basins.

The widening of the crust along the boundary is a gradual process that can occur over millions of years. It leads to the formation of new oceanic crust and contributes to the continuous movement of the Earth's tectonic plates.

No, the above statement is false. A star system may undergo two or more supernova outbursts, but not nova outbursts.

A nova occurs in a binary star system where one star is a white dwarf and the other is a main sequence or giant star. The white dwarf accretes material from its companion, and when enough material accumulates on its surface, a thermonuclear explosion occurs, resulting in a nova outburst. However, this event does not cause the destruction of the white dwarf.

On the other hand, a supernova is a much more powerful and catastrophic event that occurs at the end of a massive star's life. When a massive star exhausts its nuclear fuel, it undergoes a core collapse, resulting in a supernova explosion. This event leads to the complete destruction of the star, leaving behind either a neutron star or a black hole.

the chief difference between fog and a cloud is

Answers

The chief difference between fog and a cloud is their location and formation. Both fog and clouds are formed by the condensation of water vapor in the air, but fog occurs near the ground while clouds are typically found in the atmosphere.

Fog is formed when the air near the surface of the earth cools, causing water vapor to condense into tiny water droplets. This process is often aided by the presence of moisture and temperature inversions, where cool air is trapped beneath warmer air.

Clouds, on the other hand, are formed at higher altitudes in the atmosphere, typically above the boundary layer of air that forms fog. Clouds are created when moist air rises, cools, and condenses into tiny water droplets or ice crystals.

While fog and clouds share a similar formation process, they have different impacts on visibility and weather conditions.

The rain shadow effect occurs when moist air from the ocean is forced to rise over a mountain range, causing the air to cool and release precipitation on the windward side of the mountain.

As the air moves over the mountain and descends on the leeward side, it becomes drier and warmer, resulting in a rain shadow where little precipitation falls. Therefore, the side of the mountain that tends to receive more rain is the windward side, while the leeward side experiences the rain shadow effect and receives less rainfall.

When the rain shadow effect is occurring, the windward side of the mountain tends to receive more rain. The rain shadow effect can have a large impact on local climate as it influences precipitation distribution. In summary, the windward side of the mountain receives more rain during the rain shadow effect.

all earthquake waves propagate through liquids and solids true
false

Answers

The statement "all earthquake waves propagate through liquids and solids" is false.

Earthquake waves, also known as seismic waves, come in three types: P-waves, S-waves, and surface waves. P-waves and S-waves are body waves that propagate through the Earth's interior, while surface waves propagate along the Earth's surface.

P-waves, or primary waves, are longitudinal waves that can travel through both solids and liquids. They are the fastest seismic waves and are the first to arrive at seismometers.

P-waves can pass through the Earth's core, which is made of molten iron, indicating that they can travel through liquids.

S-waves, or secondary waves, are transverse waves that can only travel through solids. They are slower than P-waves and arrive at seismometers after P-waves. S-waves cannot pass through the Earth's core, indicating that they cannot travel through liquids.

Surface waves, as the name suggests, propagate along the Earth's surface. They are the slowest of the three types of seismic waves and are responsible for the most significant damage during an earthquake.

Surface waves are a combination of P-waves and S-waves that have interacted with the Earth's surface.

In conclusion, P-waves can propagate through both solids and liquids, while S-waves can only travel through solids. Surface waves propagate along the Earth's surface and are a combination of P-waves and S-waves that have interacted with the Earth's surface.

what is the definition of export processing zones

Answers

Export Processing Zones (EPZ) are defined as enclaves within the borders of a country that are exclusively established to offer attractive investment opportunities to foreign investors.

They are also referred to as Free Trade Zones (FTZs), Special Economic Zones (SEZs), and Industrial Parks. These zones are commonly established in developing countries as a strategy to increase foreign investment, create employment opportunities and promote export activities.

Export processing zones offer foreign investors a wide range of incentives to stimulate their investments. They are established in areas with favorable access to ports, international airports, highways and railways, making it easier to transport goods. Some of the incentives that foreign investors enjoy in the EPZs include; 100% tax exemption on all profits earned, low land costs, low rents, and duty-free imports of machinery, raw materials, and other supplies. In addition, the EPZs have flexible labor laws that allow the investor to hire and fire workers easily, pay low wages, and offer limited benefits.

Another significant benefit of EPZs is their capacity to increase employment opportunities. The zones create thousands of jobs directly and indirectly by attracting foreign investors who establish new factories and set up new manufacturing processes. These jobs are created in sectors such as manufacturing, service provision, distribution, and transport, among others. Additionally, EPZs promote export activities, which in turn increases the country's foreign exchange earnings.

This is because the goods produced within these zones are intended for export and are exempted from taxes and tariffs that would otherwise increase production costs. EPZs, therefore, offer a win-win situation for both the investor and the host country.
