Answer:

See Explanations for answer

Explanation:

The social studies practice tests provide teachers and students with items that mirror the kinds of questions that

appear on the LEAP 2025 Social Studies assessments. To illustrate how the assessment reflects the Department’s

vision for social studies and to support teachers in their use of the practice tests, this document contains a sample of

annotated items from the LEAP 2025 Social Studies Practice Tests for grades 3-8. The annotations describe the

purpose and reasoning represented in the selected items. For additional information about the practice tests, please

see the LEAP 2025 Social Studies Practice Test Guidance.

 Grade 3

 Grade 4

 Grade 5

 Grade 6

 Grade 7

 Grade 8

SOCIAL STUDIES VISION

To be productive members of society, students must be critical consumers of the information they read, hear, and

observe. To develop and express informed opinions, they need to examine and evaluate information from an array of

sources and connect that information with their background knowledge. To understand how events happen and why

people act in certain ways, students must also make connections between what happened in the past and what is

occurring in the present. To accomplish this, students must

 use sources regularly to learn content;

 make claims that demonstrate connections among people, events, and ideas across time and place; and;

 express informed opinions using evidence from sources and outside knowledge.

Simply stated, students must delve deeply into content so that they are able to develop and support claims about

social studies concepts.

How did fossil<br> fuels form, and how<br> are they obtained<br> and used?
Usimov [2.4K]

Explanation:

Fossil fuels are important energy sources for our every day activities.

  Formation of fossil fuels

Fossil fuels forms from the accumulation and burial of organisms in a basin of deposition. Instead of the organisms decaying, they preserve their carbon content. To be worthy of becoming fossil fuels, organisms must be buried in an environment where there is little to no oxygen to fast-track decomposition of the buried organic matter. Increase in temperature and pressure causes the organic matter to transform into fossil fuels.

How are they obtained

First, different fossil fuels have their extraction techniques because they occur in different physical state of matter.

For the solids e.g coal: exploration is carried out first and if a prospect is delineated, mining engineers design the best way to extract the coal from nature. Coal is usually found laid in sedimentary beds in nature. Top layers of sediments can be removed to extract the coal.

For fluids such as crude oil and natural gas, after a prospect is identified, a rig is usually constructed to extract the fluid and gas. The natural pressure allows for the fluids the rise within the drill used in extraction.

How are they used

Coal and gas are used to power electrical generating plants. They are used to heat steams which drives turbines and produce electricity.

Natural gas is used as a domestic fuel for cooking and so also coal.

When crude is processed a lot of product is obtained. Gasoline is used to power most internal combustion engines. Some chemicals useful for manufacturing plastics, drugs e.t.c are also derived from the processed crude.
