Therefore, in terms of water movement, chalk allows easy water flow, while clay resists it.<\/li>\n\n\n\n<li>Chalk is not only permeable but als<strong>o highly porous,\u00a0<\/strong>meaning it has many tiny holes or voids within its structure. These pores can<strong>\u00a0hold water, allowing chalk to absorb and retain moisture.\u00a0<\/strong>This is one of the reasons why chalk feels damp in humid conditions and can crumble easily when wet. Its porous nature is directly responsible for its ability to<strong>\u00a0absorb water,\u00a0<\/strong>which also contributes to its use in agriculture and construction, where water interaction is important.<\/li>\n\n\n\n<li><strong>Clay is highly porous, as it contains many tiny pores between its fine particles. However, these\u00a0<\/strong>pores are so small that water moves through them very slowly, making\u00a0<strong>clay poorly permeable.\u00a0<\/strong>This is why clay retains water and drains slowly, despite having high porosity.<\/li>\n<\/ul>\n\n\n","protected":false},"excerpt":{"rendered":"<p>Statement I:&nbsp;In the context of effect of water on rocks, chalk is known as a very permeable rock whereas clay is known as quite an impermeable or least permeable rock.&nbsp;&nbsp;&nbsp; Statement II:&nbsp;Chalk is porous and hence can absorb water.&nbsp; Statement III:&nbsp;&nbsp;Clay is not at all porous.&nbsp; Which one of the following is correct in respect&#8230;<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_kad_blocks_custom_css":"","_kad_blocks_head_custom_js":"","_kad_blocks_body_custom_js":"","_kad_blocks_footer_custom_js":"","_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":"","footnotes":""},"categories":[3,1],"tags":[37],"years":[63],"class_list":["post-2842","post","type-post","status-publish","format-standard","hentry","category-prelims","category-upsc","tag-geography","years-63"],"acf":[],"taxonomy_info":{"category":[{"value":3,"label":"Prelims"},{"value":1,"label":"UPSC"}],"post_tag":[{"value":37,"label":"Geography"}],"years":[{"value":63,"label":"2025"}]},"featured_image_src_large":false,"author_info":{"display_name":"LotusArise","author_link":"https:\/\/lotusarise.com\/qna\/author\/team-lotusarise"},"comment_info":0,"category_info":[{"term_id":3,"name":"Prelims","slug":"prelims","term_group":0,"term_taxonomy_id":3,"taxonomy":"category","description":"","parent":1,"count":1251,"filter":"raw","cat_ID":3,"category_count":1251,"category_description":"","cat_name":"Prelims","category_nicename":"prelims","category_parent":1},{"term_id":1,"name":"UPSC","slug":"upsc","term_group":0,"term_taxonomy_id":1,"taxonomy":"category","description":"","parent":0,"count":1269,"filter":"raw","cat_ID":1,"category_count":1269,"category_description":"","cat_name":"UPSC","category_nicename":"upsc","category_parent":0}],"tag_info":[{"term_id":37,"name":"Geography","slug":"geography","term_group":0,"term_taxonomy_id":37,"taxonomy":"post_tag","description":"","parent":0,"count":167,"filter":"raw"}],"_links":{"self":[{"href":"https:\/\/lotusarise.com\/qna\/wp-json\/wp\/v2\/posts\/2842","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/lotusarise.com\/qna\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/lotusarise.com\/qna\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/lotusarise.com\/qna\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/lotusarise.com\/qna\/wp-json\/wp\/v2\/comments?post=2842"}],"version-history":[{"count":0,"href":"https:\/\/lotusarise.com\/qna\/wp-json\/wp\/v2\/posts\/2842\/revisions"}],"wp:attachment":[{"href":"https:\/\/lotusarise.com\/qna\/wp-json\/wp\/v2\/media?parent=2842"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/lotusarise.com\/qna\/wp-json\/wp\/v2\/categories?post=2842"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/lotusarise.com\/qna\/wp-json\/wp\/v2\/tags?post=2842"},{"taxonomy":"years","embeddable":true,"href":"https:\/\/lotusarise.com\/qna\/wp-json\/wp\/v2\/years?post=2842"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
