small fields, often land they don't own where do subsistence farmers grow their food?
Subsistence farmers often grow their food in small fields or plots of land that they do not own, typically on a local or communal basis.
Small pieces of land or fields that are not their own are frequently farmed by subsistence farmers, who depend on agriculture for their livelihood rather than for financial gain. These lands may be communal, rented, or even ones to which they have unofficial access.
These areas may be farmed by subsistence farmers utilising conventional or low-input agricultural techniques, such as manual labour, basic equipment, and conventional seed types. With little to no excess for trade or sale, they frequently raise staple crops like grains, vegetables, and legumes to support themselves and their families.

larger groups would quickly use up all of the food within walking distance Why did hunter gatherers live in small groups? (usually less than 50)
Hunter-gatherers lived in small groups due to limitations of food availability within walking distance, necessitating mobility for foraging and avoiding overexploitation of local resources.
Because bigger populations would soon deplete the nearby food supplies, hunter-gatherers lived in compact communities. Foraging and avoiding over-exploitation of the ecosystem required mobility. Smaller groupings enhanced social cohesiveness and collaboration decreased rivalry for scarce resources and allowed for flexibility in the search for new food sources.
Smaller groups were also easier to manage in terms of social coordination, decision-making, and mobility—all of which were essential for surviving in a nomadic lifestyle dependent on hunting, gathering, and resource sharing among group members.

which description is evidence for the theory of plate tectonics but does not suggest that the continents were once connected?
One piece of evidence for the theory of plate tectonics that does not necessarily suggest that the continents were once connected is the observation of seafloor spreading.
This process occurs at mid-ocean ridges, where new oceanic crust is formed through volcanic activity and gradually moves away from the ridge in opposite directions.
As the oceanic plates move apart, they carry with them the continents that are located on top of them, causing them to gradually shift their positions. However, while this movement can result in the continents moving closer together or farther apart, it does not necessarily mean that they were once joined together as a single landmass.
Therefore, the observation of seafloor spreading provides evidence for plate tectonics, but does not necessarily imply the existence of a supercontinent like Pangea in the past.

from the perspective of plate tectonics, how were the himalayas and other neighboring mountain chains formed?
The Himalayas and neighboring mountain chains were formed as a result of the collision between the Indian subcontinent and the Eurasian plate. This process is known as continental collision and is a key concept in plate tectonics.
Around 50 million years ago, the Indian subcontinent was located far to the south of its current position, moving northwards towards Eurasia at a rate of around 15 centimeters per year. As it approached the Eurasian plate, the denser oceanic crust of the Tethys Sea (which separated the two continents) began to subduct (sink) beneath the lighter continental crust of both plates.
The collision between the two plates caused the Indian subcontinent to crumple and fold, creating the Himalayan mountain range and other mountain chains such as the Karakoram and the Hindu Kush. This process is known as mountain building or orogeny.
The collision is ongoing, and the Himalayas are still rising at a rate of around 5 millimeters per year due to the continued convergence of the Indian and Eurasian plates. This has resulted in the creation of some of the highest peaks in the world, including Mount Everest, which stands at 8,848 meters above sea level.

Recent sea level increases are largely associated with __________.A. thermal expansion of the oceansB. land subsidenceC. melting of ice caps
Recent sea level increases are largely associated with A. thermal expansion of the oceans and C. melting of ice caps. The oceans are absorbing more than 90% of the excess heat trapped by human-emitted greenhouse gases, causing the seawater to expand and take up more space, thus leading to thermal expansion of the oceans.
On the other hand, melting of ice caps contributes to rising sea levels by introducing more water to the oceans. Climate change has led to increasing temperatures globally, causing more ice to melt and contribute to sea level rise.
Land subsidence, which is the sinking of land due to natural or human-caused factors such as groundwater pumping, can also play a role in sea level rise in certain areas, but it is not a major contributor to the global sea level rise trend.

A u-shaped body of water that is formed when a river bend is cut off is called an oxbow lake. Oxbow lakes are formed due to erosion and deposition processes in a river system. The correct option is e.
As a river flows, it erodes the outer banks of a bend, while deposition occurs on the inner banks. Over time, the erosion causes the bend to become more pronounced, and the river channel to become narrower.
Eventually, the river may cut through the narrow neck of the bend, and the water will flow along the straighter channel. This leaves behind an abandoned meander loop, which becomes an oxbow lake.
